Title: Fusion reaction by three stages of laser bombardment - with increasing energy and shorter duration also reflectors for second stage
Inventor: LUBIN MOSHE JOEL
IPC: H05H1/22
Filed: 1975-01-07
Abstract: A method of operating a thermonuclear reactor consists of introducing heated, liquid lithium from a heat exchanger tangentially into a pressure vessel, then abstracting it from the vessel back to the heat exchanger, so as to form a central cavity in the pressure vessel, thermonuclear fuel pellets are intermittently, individually fed into this central cavity and bombarded by a laser beam to initiate a fusion reaction, the fast neutrons thus produced breed tritium in the liquid lithium, this tritium being removed in the heat exchanger, the heat produced in the heat exchanger drives a steam turbine to generate electricity. The laser beam is subdivided into successive pulses, a first pulsed beam oriented directly into the cavity zone on the path of the fuel pellets and having a selected energy and duration (esp. 1-2 Joules and 10-8- 10-9 secs) to evaporate and slightly ionise the pellets and thus form a plasma, a number of second, pulsed laser beams immediately following the first pulse and reflected from surfaces below the plasma to 'tailor' the plasma, these having a higher energy and shorter duration than the first beam (esp. 200-400 J and 10-8 -10-10 secs) a third pulsed high-energy firing laser beam having a still higher energy and still shorter duration (esp. 105J and 10-9-10-11 secs) and oriented directly into the 'tailored' plasma, to cause a fusion reaction inside it. Each of these steps is repeated for each individually introduced fuel pellet to obtain an optimum energy output level. Cryogenic magnetic fields are not required. Damage to the vacuum wall of the reactor by fast neutrons is substantially eliminated. A tritium breeder ratio greater than unity is obtd.

Patent DE-2608040-A1 (DE)
Inventor: MUELLER JUERG
IPC: G01L9/00
Filed: 1976-02-27
Abstract: The durability of goods preserved in hermetically sealed containers is only guaranteed if certain limit values of the internal pressure are maintained. Just as a string which is tensioned to a greater or lesser extent changes its tone, the vibration behaviour of the lid of a hermetically sealed container also changes with varying underpressure or overpressure. The invention makes it possible to infer the pressure conditions prevailing in the container (7) from the vibration behaviour of a container lid (6) which is made of ferromagnetic material and is under overpressure or underpressure. An electromagnet (4, 5) situated just above the lid (6) is excited by means of a frequency generator (1) in such a way that it generates a magnetic alternating field of approximately constant amplitude in the vicinity of a selected frequency spectrum by means of the band-pass filter (2). The vibrations emitted under these circumstances by the lid (6) are fed to a frequency/direct voltage converter (10) via a microphone (8). This converter has a pass band which is between the lower cutoff frequency of the band-pass filter (2) and an upper cutoff frequency forming the reject/accept criterion of the test operation. A downstream threshold switch (11) responds only to a resonance frequency in the pass band. <IMAGE>
