摘要：

The influence of pre-ionization around the insulator sleeve of plasma focus, by a mesh-type beta-source Ni-28(63) on neutron emission is investigated. The experiment is conducted on two low-energy (1.15 and 0.58 kJ) Mather-type plasma focus devices. The neutron emission is found to be increased by upto 25%. The results of this experiment suggest that pre-ionization may be helpful in designing a device as a sealed neutron source for different field applications.
