在GSI亥姆霍兹重离子研究中心，研究了重离子和激光产生等离子体的联合实验。作为利用间接加热靶的准备，其中转换器空腔提供热辐射以产生更均匀的等离子体，必须表征该转换器靶。在本文中，这些测量的最新结果。用波长为532 nm、能量为30 J的激光加热直径在600 ~ 750 μm之间的小球形腔。辐射温度可以通过时间分辨和时间积分诊断来确定，并且实现了高达35 eV的最大值。
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.
