我们研究了利用富氢靶材料的激光离子源产生质子束。通常，基于气体的物质不适合于激光离子源，因为致密激光靶的形成是困难的。为了实现可靠的操作，我们使用亚纳秒Q开关Nd-YAG激光器测试氢化物靶，这可能有助于抑制靶材料的消耗。我们检测到足够的质子产额从氢化钛靶在实验过程中没有退化的束流。亚纳秒激光和压缩氢化物靶的组合可以提供稳定的质子束。
We studied proton beam production from a laser ion source using hydrogen rich target materials. In general, gas based species are not suitable for laser ion sources since formation of a dense laser target is difficult. In order to achieve reliable operation, we tested hydride targets using a sub nanosecond Q-switched Nd-YAG laser, which may help suppress target material consumption. We detected enough yields of protons from a titanium hydride target without degradation of beam current during the experiment. The combination of a sub nanosecond laser and compressed hydride target may provide stable proton beam.
