摘要

报道了利用质子增强背散射和扫描电镜等方法，研究不同工艺制作的钛膜靶和不同纯度的Ａｌ２Ｏ３中注入的４Ｈｅ在室温下的行为．研究结果表明，离子束增强淀积新工艺制备的钛膜与基体的结合强度优于原来热蒸发镀制的钛靶；氦在Ａｌ２Ｏ３与在钛靶中具有不同的释放机制；钛靶的起泡注入剂量在４×１０１７－７×１０１７Ｈｅ／ｃｍ２之间，而且起泡剂量与泡破裂剂量相差不大；较之新工艺制备的钛靶，氦在Ａｌ２Ｏ３中更不易形成氦泡．

Abstract

At room temperature

the proton enhanced backscattering technique and scanning electron microscopy are used to study the behaviour of implanted helium in titanium forget with different manufacturing process and alumina with different purity. The result proves that adhesion of the titanium film Prepared by ion.beam enhanced deposition（BED） is superior to that of the film made by vaporization.The release mechanism of helium in titanitum target and alumina is different.Compared with the titanium target made by IBED

helium in alumina is difficult to form bubbles.For titanium target

the implanted He dose for blistering is 4×1017-7×1017He/cm2

and this dose is very close to the dose value that makes flabes.
