Intensive neutron source based on powerful electron linear accelerator LIA-30 and pulsed nuclear reactor FR-l

摘要

Some results of investigations on joint operation modes of linear induction electron accelerator LIA-30 (∼40 MeV, ∼100kA, ∼20 ns) and pulse reactor FR-l with compact metal core with the aim of high intensive neutron fluxes receipt are given. Multiplication Q factor for prompt neutrons in FR-l booster mode operation changed from 100 to 4500. Total output of prompt neutrons from FR-1 at Q=2570 was 1.4·1016 1/puls with pulse half width ∼25 µs.
