Аннотация

Results of modelling of interaction of powerful proton beam with metallic targets of various thickness are presented. A tendency of increasing of normal component of amplitude of gas-kinetic recoil pulse with the growth of target thickness L to projected ion pass length R of the beam has been found. Asymptotic saturation of L at L = 15 R has been observed. Dependence of normal component of recoil pulse on time under target thicknesses up to 2.5 R had a non-monotonous character due to the process of expansion of compression wave on the back face of the target. Efficiency of conversion of pulse energy of ion beam to kinetic energy of irradiated substance for semi-infinite target exceeds twice or more that one for the case of foils with the thickness of the R order.
