As of June 2010, construction has begun an additional end station, Hall D, on the opposite end of the accelerator from the other three halls, as well as an upgrade which doubles the beam energy to 12 GeV. Concurrently, an addition to the Test Lab, (where the SRF cavities used in CEBAF and other accelerators used worldwide are manufactured) is being constructed.
JLab houses the world's most powerful tunable free-electron laser, with an output of over 14 kilowatts. The United States Navy funds this research to develop an laser that could shoot down missiles. Because the lab does classified military research, it is closed to the public except for an open house held once every two years.
The JLab free-electron laser uses an energy recovery LINAC. Electrons are injected into a linear accelerator. The fast-moving electrons then pass through a wiggler which produces a bright laser light beam. The electrons are then captured and steered back to the injection end of the LINAC where they transfer most of their energy to a new batch of electrons to repeat the process. By reusing the electrons and most of their energy, the free-electron laser requires less electricity to operate. The JLab is the first energy recovery LINAC to produce ultravoliet light. Cornell University is now trying to build one to produce X-rays.
Since CEBAF has three complementary experiments running simultaneously, it was decided that the three data acquisition systems should be as similar as possible, so that physicists moving from one experiment to another would find a familiar environment. To that end, a group of specialist physicists was hired to form a data acquisition development group to develop a common system for all three halls. CODA, the CEBAF Online Data Acquisition system, was the result
CODA is a set of software tools and recommended hardware that helps build a data acquisition system for nuclear physics experiments. In nuclear and particle physics experiments, the particle tracks are digitized by the data acquisition system, but the detectors are capable of generating a large number of possible measurements, or "data channels".
The ADC, TDC and other digital electronics are typically large circuit boards with connectors at the front edge that provide input and output for digital signals, and a connector at the back that plugs into a backplane. A group of boards are plugged into a chassis, or "crate", that provides physical support, power and cooling for the boards and backplane. This arrangement allows electronics capable of digitizing many hundreds of channels to fit into a single chassis.
In the CODA system, each chassis contains a board that is an intelligent controller for the rest of the chassis. This board, called a ReadOut Controller (ROC), configures each of the digitizing boards upon first receiving data, reads the data from the digitizers, and formats the data for later analysis.
Veszprém
Veszprém (ˈvɛspreːm; ) is one of the oldest urban areas in Hungary, and a city with county rights. The city is not far from Lake Balaton. about 15 km (9 mi). It is the administrative center of the county (comitatus or 'megye') of the same name.
Veszprém lies on both sides of the Séd creek, approximately from Budapest (via the M7 highway and Road 8). It can also be reached from Győr via Road 82 and from Székesfehérvár via Road 8.

William Golding
Sir William Golding (19 September 1911 – 19 June 1993) was an English writer. He was a novelist, poet, playwright and teacher. He is famous for his novel "Lord of the Flies". He received the Nobel Prize for Literature in 1983. In 2008, "The Times" ranked Golding third on its list of "The 50 Greatest British writers since 1945".
Golding was born in Newquay, Cornwall, England on 19 September 1911. He grew up in Marlborough, Wiltshire. His father, Alec Golding, was a schoolmaster at Marlborough Grammar School. Golding and his older brother, Joseph, went to their father's school. In 1930, Golding went to Brasenose College at the University of Oxford. He studied Natural science and then English literature there. Golding graduated with an MA in 1935.
Golding then worked as an actor, producer and a writer. Then he became a teacher at Bishop Wordsworth's School, Salisbury. Golding joined the Royal Navy in 1940. When World War II ended, Golding continued teaching and writing. He left Bishop Wordsworth's School in 1961 and began writing full-time.
Golding's first published novel was "Lord of the Flies". Golding used his experience of the Second World War and his teaching knowledge of children to write the book. "Lord of the Flies" is a story about a group of school boys who are trapped on a desert island. The children quickly become savages and begin to murder each other. The novel gained widespread interest because of its political message.
Golding went on to write many more books, including "The Inheritors", "Rites of Passage" and many others. He had a rather pessimistic view of humanity. His novels are often set in closed communities, such as islands, villages, monasteries, groups of hunter-gatherers, ships at sea or a pharaoh's court.
Golding was knighted for his work in 1988. He died five years later, on 19 June 1993, of heart failure in Cornwall.
Verse-chorus form
Verse-chorus form is a musical form that is common in popular music. Verse-chorus forms have been the basis for rock music since the 1960s.
Homesickness
Homesickness is a feeling of unhappiness a person may have when away from home or from familiar surroundings or people. It has a similar meaning to the word "nostalgia".
Homesickness is not about how much you miss your home. It is about how much dependent you are on other people or your parents, how much pampered you are or how much difficult it is for you to be in a different place. People sometimes become homesick when they travel. They miss their own home and desperately want to go back. Children may often feel homesick, especially when they are away from their parents for the first time. Usually these feelings will go away as one gets used to the new environment, but sometimes homesickness can make a person depressed.
People may easily feel homesick if they travel to an environment in which the culture is very difficult to what they are used to, and especially if a foreign language is being spoken. Children who are sent away to boarding school will very often feel homesick.
A good way to help children overcome (or avoid) homesickness is to start with being away from home just for short periods, staying with people they know well, e.g. grandparents or good friends.
