Upgrading of the RS-20E High-Current Accelerator for the Investigation of Shock-Wave Processes under Isochoric Energy Absorption

The scheme and parameters of the upgraded RS-20E electron beam generator on the basis of a plasma opening switch (POS) are presented. The output unit of the POS is modified to allow the use of optical diagnostics in investigating wave processes generated in transparent targets by the electron beam of the accelerator. A new optical diagnostic system is also presented. Its scheme allows the four-frame electron-optical registration of a sample in both its own glow and in the laser shadow during propagation of the shock wave generated by the electron beam.
