High-current nanosecond accelerator "Tonus-NT"

In the work presented, the new technical development of the high-current electron accelerator "Tonus-NT" (Tomsk nanosecond accelerator-new technologies) is described. It has been developed taking into account the experience of 30-years exploitation of the previous analogue-the accelerator "Tonus". The scheme of the accelerator includes the high-voltage transformer with resonant contours (Tesla transformer) charging the double forming line filled with the transformer oil and the high-voltage diode. The gas-filled trigatron spark gap with up to 10 atm operating pressure is used for the double forming line switching. The main accelerator parameters are as follows: accelerating voltage range 0.4-1.0 MeV, line impedance 36.6 /spl Omega/, pulse duration 60 ns, pulse repetition rate up to 10 pps.
