81-7M-01-A two-beams accelerator

The authors report a two-beams accelerator (named 81-7M-01-A) with one Marx generator operating one 6 /spl Omega/ water Blumlein line and another 40 /spl Omega/ oil Blumlein line at the same time by the use of a magnetic flux coupling isolator to generate two electron beams with different ranges of beam currents. The electron energies and the amplitudes of beam currents may be adjusted respectively in quite large ranges. The functions of this accelerator are equal to that of the operation of two sets of IREBA with different impedances at the same time. In this paper, the operation mechanism of the accelerator is outlined, the design method is put forward and the experiment results are presented. The design parameters are in good agreement with the experiment results.
