【摘要】 为认识脉冲离子束作用下金属氚化物的氦释放行为,建立了脉冲离子束作用下金属氚化物氦释放测量系统。利用标准体积气体取样装置,采用气体反扩散法,对系统的容积比、灵敏度进行了实验标定。在此基础上,发展了脉冲离子束作用下金属氚化物氦释放的测量技术,开展了脉冲离子束作用下金属氚化物氦释放实验研究。结果显示,单次脉冲离子束作用下金属氚化物的氦释放呈脉冲式,释放量最大可达10¹³个原子以上。更多还原

【Abstract】 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 ³ He atoms per pulse is up to 10¹³.更多还原
