Experimental Study of ³He Release from Metal Tritide under Bombardment of Pulsed Ion Beam

An experimental system for the measurement of ³He release from metal tritide was established to explore ³He release behavior under the bombardment of pulsed ion beam. The volume ratio and sensitivity of this system were calibrated by the gas back-diffusion method using air sample device and standard volume gas sample device. Based on this, an experimental technology for the measurement of ³He release under the bombardment of pulsed ion beam was developed. The ³He release of metal tritide was studied under the bombardment of pulsed ion beam. It indicates that the ³He release is in pulse, and the ³He atoms per pulse is up to 10¹³.
