| 摘 要： | 在SILEX-Ⅰ装置上进行了超短超强激光与氘团簇相互作用的实验。采用法拉第筒测量了激光与氘团簇靶相互作用后发射出的氘离子能谱，并根据氘离子能谱计算出氘团簇的尺寸和分布。由于激光预脉冲的影响，得到了团簇的尺度比瑞利散射测量的结果小。这些结果对团簇源制备系统的改进和优化激光打靶有着重要的参考意义，而且可以为团簇尺度的测量提供一种新的方法。

| Abstract: | Experiments on the interaction of deuterium clusters with intense laser pulses have been performed on SILEX-Ⅰ. Faraday cups were used to characterize the deuterium ions emitted from laser irradiated gas plumes. The size and its distribution of the deuterium clusters were calculated using energy spectra of the ions, developing a new calibrating method of cluster size. Due to the influence of laser prepulse, the resulting cluster size is smaller than that by Rayleigh scattering. The results are important for analyzing clusters’ interaction with intense lasers, and they may provide guidelines to choose proper fire time. |
