摘要 根据超短超强激光与固体靶相互作用中质子靶前表面加速和靶后表面加速两种机制,对在SI-LEX-I激光器上进行的质子加速实验中获得的质子最大截止能量进行了估算,认为实验中质子产生的主要机制是靶后表面加速。同时结果表明:对该装置的实验条件,靶前表面加速机制可以产生质子的最大能量约为2MeV;靶后表面加速机制可以产生的质子的最大能量约11 MeV。另外用Multi2005程序计算了激光器信噪比对靶后表面加速机制的影响。计算表明:SILEX-I激光器信噪比达到108∶1时,预脉冲对用5μm靶时鞘层加速电场的影响可以忽略。 Cut-off energy of proton accelerated in experiment on SILEX-Ⅰ is estimated, according to the front mechanism and rear side mechanism of interaction between ultrashort ultra-intense laser and solid target. The estimation according to the rear side mechanism agree well with experimental data. Meanwhile, the maximum proton energy accelerated in interaction of short laser pulse with solid targets on SILEX-Ⅰ is also calculated： 11 MeV for the rear side mechanism and 2.0 MeV for the front side mecha- nism. Besides, the influence of prepulse to accelerating field is estimated by Muhi2005 code and it can be neglected when signal-to- noise ratio is better than 10^8 ： 1.
