我们报告了一个新的实验装置，用于测量密度中等耦合等离子体中的离子能量损失，该装置最近在GSI达姆施塔特进行了开发和测试。用软X射线对两片薄碳膜进行体加热，产生了部分电离的中等耦合碳等离子体（ne ≤ 0.8· 1022 cm-3，Te = 15 eV，z = 2.5，Γ = 0.5）。然后用一束重离子束探测这种等离子体。为此，一种特殊的双金腔靶的亚毫米尺寸已被开发，有效地将强激光转换成热辐射，并保证了一个无金的相互作用路径的离子束穿过碳等离子体。这种设置允许在10%固态密度的水平下在非理想等离子体中进行精确的能量损失测量。
We report on a new experimental setup for ion energy loss measurements in dense moderately coupled plasma which has recently been developed and tested at GSI Darmstadt. A partially ionized, moderately coupled carbon plasma (ne ≤ 0.8• 1022 cm-3, Te = 15 eV, z = 2.5, Γ = 0.5) is generated by volumetrical heating of two thin carbon foils with soft X-rays. This plasma is then probed by a bunched heavy ion beam. For that purpose, a special double gold hohlraum target of sub-millimeter size has been developed which efficiently converts intense laser light into thermal radiation and guarantees a gold-free interaction path for the ion beam traversing the carbon plasma. This setup allows to do precise energy loss measurements in non-ideal plasma at the level of 10 percent solid-state density.
