The sheet metal tanks that held the cooling oil leaked.  "We all wore paper hats," Livingston recalls, "to keep the oil out of our hair."  Experimentation with shimming gradually brought the beam to larger radii and energies; two symmetric dees were installed; and in December the new 27-inch cyclotron produced 4.8 MeV hydrogen ions.

With the onset of World War II, the project  became a wartime priority. TheRockefeller  Foundation pledged the principal amount,  $1.4 million, in April 1940. It was to buy a  cyclotron with a magnet face 184 inches in  diameter. The machine would open the frontier  beyond 100 MeV, where there lurked 'discoveries  of a totally unexpected character and of  tremendous importance.' But wartime uses  intervened. The magnet was adapted for use in a  'Calutron,' a huge mass spectrograph to test the  feasibility of Lawrence's plan to separate the  fissile, or explosive, part of natural uranium,  U-235, from its much more plentiful companion  isotope, U-238.  This work led to the  establishment of large-scale calutron facilities  at Oak Ridge.  After the war, the 184-inch  cyclotron was completed as a synchrocyclotron,  or synchrotron, incorporating the principle of  phase stability developed by Edwin McMillan and  Vladimir Veksler.  It became a valuable instrument for physics and, later, for biological and medical research. Its most important achievements include: the first production and identification of a  subnuclear particle (the charged pi meson, or  pion) at an accelerator; studies of the  interaction and properties of  pions; studies of  proton-proton and neutron-proton interactions;  and use of heavy particles for medical therapy. It ended operation in the 1980s, and the domed  structure that housed the cyclotron was adapted to house the Berkeley National Advanced Light  Source.  -- JG

Since Rutherford thought that tritium is stable, he required a reason why he could not obtain it from the plentiful interactions of deuterons. His answer: tritium disappears quickly by combining with the bombarding deuterons. As for helium-3 the consensus, as represented by H. A. Bethe, held it to be unstable, decaying into the elusive tritium by electron capture. It was precisely with this preconception- that tritium is elusive but stable and helium-3 is radioactive-that Luis Alvarez went to look for them in the summer of 1939. (The preceding information was excerpted from the text of the Fall 1981 issue of LBL Newsmagazine.)

The stability of helium-3 implied the radioactivity of tritium.  Alvarez tested this inference with the help of Robert Cornog, a graduate student who worked on the oil vapor vacuum pumps for the 60-inch machine.   They routed the issue of heavy water irradiated with deuterons into an ionization chamber attached to an amplifier and found a long-term activity whose carrier behaved like hydrogen The number of active atoms agreed roughly with the number of neutrons produced in the bombardment, confirming the formation of tritium and a proton from two deuterons.

Soon after he began his search for useful radioisotopes, Lawrence had the good luck to make sodium-24 efficiently by bombarding rock salt with deuterons. The new substance runs through the body like ordinary sodium; its convenient half-life, fifteen hours, made it useful in diagnosis and therapy. "My medical friends tell me that the properties of radiosodium are almost ideal for many medical applications, such as the treatment of cancer." Lawrence predicted that sodium-24 would supersede radium, and to make sure he promoted it on a national lecture tour. A volunteer-the first two were Alvarez and Joseph Hamilton of the University's hospital in San Francisco-would down a solution of the isotope, and Lawrence would track its course through his body.  Lawrence received fresh supplies of sodium-24 by air mail just in time for these lectures, which increased the drama, and the value, of radioisotopes.

The reorganized laboratory was dedicated to nuclear science rather than, as in its first incarnation, to accelerator physics. This transformation, as we know, resulted from opportunities opened by the discoveries of artificial radioactivity and the biological action of neutron rays, and also, perhaps, from concern about the effects of the increasingly intensive neutron background on the men who worked around the accelerator.

In August the first racetrack began to operate, successfully it was thought; but it soon collapsed, its vacuum leaky, its coils shorted, its tanks warped by its mighty magnet. Meanwhile Oppenheimer reported that a bomb would require three times as much U 235 as forecast. Lawrence and others flew in from Berkeley to diagnose the ailing racetrack, which was dismantled and returned to its manufacturers. The pressure overwhelmed even Lawrence. He spent the end of 1943 in a hospital in Chicago. (The preceding information was excerpted from the text of the Fall 1981 issue of LBL Newsmagazine.)

The new element, called plutonium on McMillan's principle of nomenclature, proved elusive.  In May 1941 Kennedy, Seaborg, Segre, and Wahl established the isotope's fissionibility. It appeared that in sufficient quantities plutonium-239 might sustain an explosive chain reaction. After Pearl Harbor, the OSRD authorized Lawrence to continue plutonium studies at Berkeley and Arthur Compton to supervise the work toward a controlled, self- sustaining, plutonium-producing chain reaction that had been started by Fermi at Columbia and moved to Chicago. In March 1942 Seaborg was asked to join Compton and Fermi to develop chemical processes to separate plutonium after production. On April 17 he boarded the train for Chicago with the world's supply of plutonium in his briefcase.

In a conventional cyclotron the relativistic mass increase ultimately shuts off acceleration: the particles fall progressively out of phase with the radio frequency field until they reach the gap between the dees as the field there drops to zero. Thereafter they will be decelerated. As McMillan (and, independently, the Soviet physicist V. I. Veksler) showed, a net acceleration might be achieved by decreasing the oscillator frequency without changing the magnetic field (the principle of the  accelerated particles describe a path of constant radius (the protonsynchroton). In the case of relativistic electrons, only the magnetic field need be altered (the electron synchrotron).

In investigating the emission of positrons from aluminum struck by alpha particles, they observed that the target stayed active after the bombardment stopped. It was a great surprise. Everyone had tacitly assumed that the explosion of a nucleus followed immediately on its swallowing an energetic particle, and had arranged his experimental practice to suit. At the Rad Lab belief that residual activity does not exist affected operations. (The preceding information was excerpted from the text of the Fall 1981 issue of LBL Newsmagazine.)

After Cockcroft, Lawrence faced Ernest Rutherford, who declared that no neutrons come from lithium under deuteron bombardment, and Chadwick, who insisted that the mass of the neutron is exactly what he had said. Then came the theorists. Heisenberg observed that if disintegration occurred in the electric field of the nucleus, the yield should decline for heavy targets since the deuteron's penetration, and hence the rate of change of force on it, must decrease with increasing atomic number.  The debate continued when Lawrence stuck his head in the Cavendish lion's den on the way back to Berkeley.

From March of 1934 until the Laboratory went to war, the investigation and production of artificial isotopes by neutron, proton, deuteron, and alpha-particle beams dominated its research program.

Other isotopes generated by his cyclotron, however, found important applications in medicine. Phosphorus-32 has been used successfully in the treatment of leukemia, polycythemia vera, other bone-marrow disorders, and Hodgkins disease; iodine-131 in the treatment of thyroid disease; and cobalt-60 in cancer chemotherapy. Perhaps the most interesting of these substances to the physicist and chemist is technetium-99, used in cancer diagnosis.  Lawrence presented this object to Emilio Segr, who visited the Laboratory in the summer of 1936 and took the "invaluable gift" to Italy, to stimulate nuclear science at the University of Palermo.  In June 1937 Segr's group announced the first element made by man. Medical application of the new element began in 1947. Half of the seventy artificial radionuclides in common use in medicine today first made their appearances in cyclotrons, and half of these were discovered, or first synthesized, at the Radiation Laboratory.

Bottom:  Rutherford's proposal that two colliding deuterons decay either to hydrogen-3 or helium-3, yeilding protons and neutrons.  Cockcroft, Marcus Oliphant, and Rutherford all dismissed the deuteron hypothesis and advised Lawrence to look for contamination of his targets or his tank. Back in the friendly West, Lawrence hastily reviewed the possibility of systematic contamination with the help of chemical colleague Lewis. The resulting paper, sent to the Physical Review  in December 1933, should have convinced "the most skeptical [according to Lawrence] that the deuteron is energetically unstable and disintegrates into a proton and a neutron." Some friends, for example Jesse Beams, thought Lawrence's answer decisive. Others, including Charles Lauritsen and Merle Tuve, repeated the experiments with immaculate apparatus and did not find Lawrence's protons. Then Rutherford found the fast protons, but only after deliberately contaminating his targets with deuterium. Lawrence's conviction waned. By April 1934, with artificial radioactivity claiming his attention, he had discarded the deuteron disintegration hypothesis.

/home/www/imglib/http/htdocs/ImgLib/COLLECTIONS/BERKELEY-LAB/ACCELERATORS/CALUTRONS/tags/pg36_diagram:	Schematic diagram of uranium isotope separation in the calutron. The world did not lack methods for separating when it discovered the possible utility of a kilogram of uranium-235 (U-235). Known techniques, pursued simultaneously in Germany and the United States, included ultra-centrifugation, diffusion across thermal or osmotic pressure barriers, and deflection in electric and magnetic fields. The last method appealed to Lawrence, who had made his reputation on the precise control of beams of charged particles. In principle the technique is simple. When passing between the poles of a magnet, a monoenergetic beam of ions of naturally occurring uranium splits into several streams according to their momentum, one per isotope, each characterized by a particular radius of curvature. Collecting cups at the ends of the semicircular trajectories catch the homogenous streams. (The preceding information was excerpted from the text of the Fall 1981 issue of LBL Newsmagazine.)

The modification  program described here was one of many that  would keep the machine working at the forefront  of physics for the next forty years. The Bevatron played the leading role in three of the most  important discoveries of particle physics:  experimental studies of "strange" particles  leading to the discovery of parity  nonconservation (the first known example of a  lack of symmetry in nature); the discovery of  nuclear antimatter (the antiprotons and the  antineutron);  and the discovery of the  "resonances" -- the particle explosion of the  1960's that led to the development of the quark  model and the current understanding of the basic  nature of matter.

It became a valuable instrument for physics and, later, for biological and medical research. Its most important achievements include: the first production and identification of a subnuclear particle (the charged pi meson, or pion) at an accelerator; studies of the interaction and properties of  pions; studies of proton-proton and neutron-proton interactions; and use of heavy particles for medical therapy.

The beam enters through pipe on right and strikes target (center). Particles coming from nuclear reaction are analyzed by the spectrometer magnet and then detected and identified by the focal plane counter system. The spectrometer is one of several new devices recently added to the 88-inch cyclotron to make it possible to do research on heavy ions.  The complete system includes an internal heavy ion source, energy- analyzing magnets, the spectrometer with a novel  detection system that identifies particle by  atomic number, atomic mass, and energy. The focus of the new heavy-ion research program will be to examine the remains of the bomarding particle to learn more about nuclear structure.  Principal investigators will include Bernard Harvey, Joe Cerny, Cornelius Tobias, and Buford Price, among others.  The 88- inch cyclotron is a variable energy, spiral- ridge machine of the sector-focused type.  Such machines maintain very high beam intensities and fairly high beam energies.  The machine first became operational in 1961. The design and  construction of the 88-inch cyclotron was led by physicist Elmer Kelly and engineer Richard  Burleigh. The experimental program at the 88-inch includes studies of nuclear reaction mechanisms, scattering and absorption of beam particles, and production of many radioactive and stable  isotopes.

The machine may be pictured as a cylindrical wave guide or resonant cavity containing a time-varying accelerating field everywhere the same. The field automatically bunches particles that enter the gaps between the drift tubes as the field is increasing there. Particles arriving slightly early (or late) receive a smaller (or larger) push than the mean, and come in better time to the next gap.

Construction is continuing, but it will soon be completed and a definite experimental and maintenance schedule established. Tjorborn Sikkeland, Al Ghiorso, and Robert Main at the Hilac.The idea for a heavy ion machine was originated by Dr. Glen T. Seaborg and Albert Ghiorso, who conferred with Drs. E. O. Lawrence and Luis W. Alvarez. They discussed building a machine to accelerate a pure beam of heavy ions (originally, nuclei of atoms up to argon-40, element 18).  In part, the machine was designed jointly by UCRL (UC Radiation Lab, now LBNL)  and Yale University.  Mechanical engineer in  charge was Hayden Gordon. Heavy ions had  previously been accelerated at the 60-inch  cyclotron, but could not be freed of low-energy  contamination.  In the Hilac, heavy ions are  accelerated without interference.  Experimenters  at the Hilac seek to synthesize new elements and  isotopes of known elements.  Another experiment  is scattering studies: in these the behavior  of the struck particles gives clues to nuclear  make-up.  The Hilac was later modified into the  SuperHILAC, and eventually became the basis for  the Bevalac, which combined the SuperHILAC and  the Bevatron. The SuperHilac was finally shut down on December 23, 1992.

Nuclei began their journey in the SuperHILAC and then were passed  through a transfer line to the Bevatron, where  they were accelerated almost to the speed of  light. With the later addition of an improved  vacuum system and other modifications, the  Bevalac became the only machine the world capable of accelerating all of the elements of the  periodic table to relativistic energies. The  Bevalac finally ceased operations on February  21, 1993.  - JG

Stanley Livingston, accelerated a few hydrogen molecule ions to an energy of 80,000 electron volts.  Since each ion received an accelerating kick twice in a circuit as it entered and left the single flat semicircular electrode or "dee," those that managed to reach full energy and fall into the collecting cup 4.50 cm from the center of the instrument had made no fewer than forty turns. The result, reported at the January 1931 APS meeting, earned Livingston his Ph.D. and Lawrence $500 from the National Research Council towards the construction of a machine that might be useful for nuclear physics.

This image depicts a typical solar neutrino event in SNO.  Neutrinos are weakly interacting particles that easily penetrate the earth.  SNO has developed a large water Cerenkov detector using heavy water (D2O) as the target.  The heavy water is contained in a 6m radius acrylic vessel.  Occasionally a neutrino will interact in the heavy water and produce a small burst of light.  To observe this light an array of sensitive light detectors (photomultiplier tubes or PMTs) surround the target and collect the light, converting it into electrical signals which are feed into SNOs data acquisition computers.  This image presents a computer simulation of a typical solar neutrino event in SNO.  The neutrino has interacted with the a deuterium nucleus, converting a neutron into a proton and an electron. The electron recoils with enough energy to produce Cerenkov light in the water which is detected by the array of PMTs.  Each yellow line segment represents a Cerenkov photon, the yellow hexagons are PMTs which detected a photon, and the geodesic sphere support structure is highlighted in magenta.

The experiment is designed to detect neutrinos emitted by the sun.  The neutrinos are a product of the energy generation processes that power the sun. While neutrinos are produced in copious quantities, they are very difficult to detect. Very large detectors are required.  These detectors are frequently sensitive very low levels of naturally occurring radioactivity and to cosmic rays.  SNO has been fortunate in locating a site 6800 feet underground in INCO's Creighton Mine near Sudbury Ontario, Canada.  This depth reduces the flux of cosmic rays to negligible levels. This image shows the cavity as it was nearing the completion of its excavation in May 1993.  The barrel shaped cavity is 22m in diameter and 35m tall.

The material slowly passes a single heating unit. Since the impurities in the germanium are more soluble in the liquid than the solid phase, as they melt they accumulate toward the last end to pass through the heated section. After 20 repetitions of this process, the bar is cooled and the far end, with its lion's share if impurities, is sawed off. The remaining section is cut into 1 kilogram pieces for the crystal melt. This process has led to the growing of the world's purest gernamium crystals at LBL.  The reason for developing high-purity germanium crystals is to improve the characteristics of semi- conductor radiation devices.

More than 40 samples of ores and rocks were examined there- without cost to BART or delay to construction work. The study convinced scientists that man is unlikely to find any superheavy elements in nature.  Nuclear chemist Stanley  Thompson's team examined more than 40 samples of ore and rock (including valuable moon rock) looking for distinctive radiation that would be expected from spontaneous fission of  superheavy nuclei.  None was found. - JG

They are shown in the computer room of the Hilac.The experiment involved using a new technique known as beam-foil  spectroscopy to create a gallery of "counterfeit elements" -- elements that masquerade as other atoms, behave like them in many important ways. The experiments stripped electrons from atoms of argon, leaving only one instead of 18.  The atom then behaved in many ways as if it were hydrogen.

Seaborg, Albert Ghiorso, James Kennedy, B. B. Cunningham, and others elaborated the rich and varied chemical properties of the actinide elements. They continued work begun during the war at Chicago where their identification of americium (element 95) and curium (96) among the products of plutonium bombarded in the Berkeley and St. Louis cyclotrons confirmed the actinide concept, the existence of a series of heavy homologues of the rare earth elements.

They called this brief encounter (or the compound constituted by it) the Y*(1385), the number signifying its resonant energy. It aroused great interest when reported at the Rochester Conference on High Energy Physics in 1960, for it implied the possibility of creating a spectroscopy for the heavier elementary particles.

Advanced Light Source electrons are generated by a high- intensity electron gun that can produce single or multiple bunches of electrons (each electron has an energy of 120,000 electron volts) in pulses of 2.5 nanoseconds (billionths of a second). These electrons then pass through the 120 accelerating chambers of the 5-meter-long linac (linear accelerator), where positive charges on the far wall of each chamber attract the electrons and accelerate them. Electrons emerging from the linac have reached an energy of 50 million electron volts and are traveling fast enough to go around the world 7-1/2 times in one second. 
/home/www/imglib/http/htdocs/ImgLib/COLLECTIONS/BERKELEY-LAB/RESEARCH-1991-PRESENT/ADVANCED-LIGHT-SOURCE/tags/96804041:	Advanced Light Source 5-cm-period undulator installed in sector 7 of the storage ring. The brightest synchrotron light at the Advanced Light Source comes from undulators (located in the straight sections of the storage ring) that contain over one hundred magnetic poles lined up in rows above and below the electron beam. The magnets force the electrons into a snake-like path, so that the light from all the curves adds together. Although they are about 4.5 meters long and weigh about 40,000 pounds, the undulators have to be built to extreme precision. Many of the design tolerances are approximately 50 microns, less than the width of a human hair.

Hundreds of precision electromagnets (blue, yellow, and orange in the photograph) focus and bend the electron beam as it circles the storage ring more than a million times a second. The synchrotron light emitted by the electrons is directed to beamlines through the round beam ports.

The linac to booster to storage-ring sequence is repeated several hundred times to fill the storage ring to its operating current (normally 250-400 milliamps).

As it emits synchrotron radiation, the electron beam loses energy, which must be replaced if the beam is to continue circulating in the storage ring. The energy is put back into the beam via two radio-frequency (rf) cavities (the copper structure at the right center in the photograph). In this way, the beam can continue to circulate for many hours while it gradually decays in intensity because of collisions between neighboring electrons in the beam, and between electrons in the beam and residual gas molecules in the storage-ring vacuum chamber.

To complete the undulator's magnetic structure, five of these assembly sections, along with two special end sections, are affixed to each of two steel backing beams. The 4.5-m-long backing beams provide magnetic shielding and stability. The end sections incorporate a system of Nd-Fe-B rotors, which are designed to cancel any net field integral in the magnetic structure, thereby preventing the electron beam from being displaced or deflected when it enters and emerges from the undulator.

To measure the magnetic field of an insertion device, the ALS designed and built a high-speed, precision magnetic measurement system. It uses Hall-probe mapping equipment to obtain local and integrated field information. Nicknamed the Luge, it consists of a custom-built stage that translates through the gap of the undulator. The system is capable of taking 2500 measurements during one pass through the insertion device in under one minute. A laser interferometer system gives precise tracking of the probe to an accuracy of 1 m.

/home/www/imglib/http/htdocs/ImgLib/COLLECTIONS/BERKELEY-LAB/RESEARCH-1991-PRESENT/ADVANCED-LIGHT-SOURCE/tags/96904221:	Photon beam position monitor (PBPM) from Advanced Light Source Beamline 7.0. The beamline has two such monitors, one inside the storage ring shielding and one outside the shield wall. PBPMs provide information on the position and angle of the electron beam at the center of the undulator. In the center of the PBPM are two copper blades that project into the path of the undulator photon beam. The photoemission of electrons from the surfaces of the blades provides signal currents to an electron-beam stabilization system. The difference in the signal current readings from the two surfaces can be used to detect movement of the beam pathas small as one micron. Information from the PBPMs is used by the feedback system to adjust the steering magnets in the storage ring, stabilizing the electron beam. The symmetry of the detector design about the line of the beam ensures that the position signal is insensitive to heating of the internal detector components by the photon beam.

Slit width can vary from a few microns to 100 m, so users can choose to maximize either spectral resolution of flux. Slit blade movement is actuated by a differential-pitch micrometer, allowing submicron control of slit width. The assembly is made of GlidCop, a copper alloy that provides seven times the strength of copper while retaining its high thermal conductivity. 
/home/www/imglib/http/htdocs/ImgLib/COLLECTIONS/BERKELEY-LAB/RESEARCH-1991-PRESENT/ADVANCED-LIGHT-SOURCE/tags/96904223:	The 5-cm-period undulators in use at the Advanced Light Source each contain two 4.55-meter-long arrays of permenent magnets with alternating polarity. The arrays are supported by a superstructure capable of resisting the force of their attraction-up to 42 tons (the weight of a 38,000 kg mass). As an electron beam passes throught a vacuum chamber between the arrays, the magnets cause the beam to curve back and forth and thus to produce synchrotron radiation. Undulators produce light brighter than that from other forms of synchrotron radiation sources and with the added characteristics of partial coherence and linear polarization. In this photograph, a strobe light emulates the electron beam.

In the process, the enzyme connects the glucose to the glycogen chain as the phosphate is released. But the accumulated pool of phosphate would cause the process to stop and even to reverse. However, when sucrose (a molecule of fructose linked to glucose) and the enzyme sucrose phosphorylase are added, the enzyme connects a phosphate from the pool to the glucose and the fructose is released. The newly created glucose phosphate joins the pool and the process begins again. 
/home/www/imglib/http/htdocs/ImgLib/COLLECTIONS/BERKELEY-LAB/RESEARCH-1991-PRESENT/LIFE-SCIENCES/tags/96703453:	In the synthesis of an enzyme, a recipe for the sequence of amino acids is carried from DNA by messenger RNA (mRNA) in condons - arrangements of three nitrogenous bases for each amino acid. A transfer RNA (tRNA) molecule with a matching anticodon binds the appropriate codon on the mRNA, delivering the correct amino acid, which is attached to the growing protein chain. In site- directed mutagenesis (lower left), a chosen codon is replaced by another so that a different tRNA will bond and a different amino acid will be attached to the chain. A similar technique is used to replace natural amino acids with synthetic, non-natural amino acids (lower right). Here the chosen codon is changed to one that usually signals the end of the protein and has no tRNA to match. It is read by a specially designed and synthesized tRNA carrying the synthetic amino acid.
