The energy loss, produced by shielding effect of steel cage outside the source tube, is quite considerable. With PENELOPE software package, MC results have been
The pH-sensitive polyacrylic acid (PAA) hydrogels were synthesized by gamma-ray irradiation at an am- bient temperature. The influences of dose, monomer concent
Co-55 (t1/2=17.53 h) was produced by 150 μA irradiation of a natural nickel target using 15 MeV protons. It was separated from the irradiated target material b
In this paper,to design a new preamplifier for optimum performances with charged-particle or heavy-ion detectors,the CMOS FET is implemented as a feedback capac
