摘要:

A new method which suppresses target preheating by hot electrons is proposed. The suppression was verified by means of particle measurements on the rear side of a foil irradiated by a CO2laser with a thick plate placed in front of the irradiated foil to absorb the energetic electrons which preferentially expand from the critical surface. The results can be explained by the generation of the electrostatic field between the foil and the plate.
