- Аннотация: After achieving thermonuclear ignition in inertial confinement fusion (ICF), a new stage ofresearch began, the ultimate goal of which is creation of an industrial ICF reactor for generating electricenergy. This work is devoted to radiation stability of the optical components of ICF reactor chamberand a promising KrF laser driver as one of the unsolved problems along this path. The adaptationof a ten-megaelectronvolt pulsed linear electron accelerator with an average power of 15 kW for testinga number of optical materials transparent to UV radiation of KrF laser is described. With a peak electronbeam power of 4 MW and a repetition rate of 8-μs pulses of 50 Hz, the accelerator provideda maximum dose rate of electron irradiation of materials of 2.5 kGy/s at controlled temperature ofoptical samples under conditions close to the operation of KrF laser driver windows. The results ofcurrent and dosimetric measurements are in good agreement with Monte Carlo calculations.
