Cut-off energy

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.

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。
