At the GSI Helmholtz center for heavy-ion research combined experiments with heavy ions and laser-produced plasmas are investigated. As a preparation to utilize indirectly heated targets, where a converter hohlraum provides thermal radiation to create a more homogeneous plasma, this converter target has to be characterized. In this paper the latest results of these measurements are presented. Small spherical cavities with diameters between 600 and 750 μm were heated with laser energies up to 30 J at 532-nm wavelength. Radiation temperatures could be determined by time-resolved as well as time-integrated diagnostics, and maximum values of up to 35 eV were achieved.
在GSI亥姆霍兹重离子研究中心,对重离子与激光产生等离子体的联合实验展开了研究。作为利用间接加热靶的准备工作,其中一个转换黑腔提供热辐射以产生更均匀的等离子体,必须对这个转换靶进行特性描述。本文展示了这些测量的最新结果。直径在600至750微米之间的小型球形腔,在波长为532纳米的情况下,用高达30焦耳的激光能量进行加热。辐射温度可通过时间分辨以及时间积分诊断来确定,并且实现了高达35电子伏特的最大值。
