摘要：

进行了辐射冷却对等离子体射流影响的初步实验研究。薄（3 μ m- 5 μ m）锥形壳体用强激光照射，驱动速度> 100 km/s的射流。通过使用不同的目标材料-铝，铜和金-辐射损失的程度被改变，和他们的重要性射流准直调查。一些时间resoved光学诊断，提供有关射流演变的信息。金射流被认为是窄于那些从铜目标，而铝目标产生的准直流量最少。

英文摘要：

Preliminary experiments have been performed to investigate the effects of radiative cooling on plasma jets. Thin (3 um - 5 um) conical shells were irradiated with an intense laser, driving jets with velocities > 100 km/s. Through use of different target materials - aluminium, copper and gold - the degree of radiative losses was altered, and their importance for jet collimation investigated. A number of temporally resoved optical diagnostics was used, providing information about the jet evolution. Gold jets were seen to be narrower than those from copper targets, while aluminium targets produced the least collimated flows.
