Megampere electron ion nanosecond accelerator

An accelerator with the following beam parameters was considered as a design project: (1) power 10 TW; (2) impedance 0.05 Ohm; (3) current (electronic) 10 to 15 MA and (ionic) 1 to 3 MA; (4) kinetic energy 0.5 to 0.7 MeV; (5) stored energy approximately 150 kJ; (6) power pulse half-width approximately 30 ns; and (7) front length 15 to 20 ns. It is proposed to achieve these parameters by means of parallel supply to the diode from two modules. Consequently two types of problems can be solved on the accelerator. First, a 507 MA module can be developed for a larger, future facility, and secondly the one-two module device can be used for investigations in the field of considerably higher currents than are possible at the present time. It appears possible to design low-impedance modules suitable for parallel or series connection in larger facilities and to carry out a wide range of experiments with beam currents approximately greater than 5 to 10 MA in an accelerator with one or two modules
