Deuterium accumulation in beryllium under irradiation with powerful pulsed plasma flows

Data on the thermal desorption of deuterium from beryllium irradiated with powerful pulsed plasma flows are presented. Two grades of beryllium, namely, TGP-56FW and S-65C, are investigated. Deuterium desorbs mainly in the temperature range 800–1400 K with a maximum at 1200 K. On average, the accumulation of deuterium in S-65C beryllium samples exceeds that in TGP-56FW beryllium samples by a factor of 3.
