Pulsed electron accelerator STRAUS-R

Basing on the developed in RFNC-VNIIEF technology of stepped forming lines a high-power nanosecond accelerator of electrons STRAUS-R has been created to produce single X-ray pulses in the mode of electron beam focusing on a target. The accelerator provides a focus spot ≤4 mm in diameter on a target and maximum X-ray dose of 0.27 Gy (Si) at 1-m distance from the output flange. The boundary energy of electrons is 3.0-3.5 MeV, the electron beam current ≤60 kA and X-ray pulse width ≤50 ns. The description of the accelerator and results of its experimental investigation are given.
