PREPARATION OF SELF SUPPORTING MULTILAYER TARGETS

The self supporting multilayer targets, C+Pb+Ni,C+Pb+Co, C+Pb+S+Al, for the use of nuclear physics experiment are prepared by vacuum evaporation method. The mass thickness of foil layer is 10~15, about 100, 30~60, 30~60, 30~50 and 10 μg·cm -2 for C, Pb, Ni, Co, S and Al, respectively. The prepared targets can meet the requirements of nuclear physics experiment.
