摘要

In many experiments, plastic scintillators are used as a counter instead of Geiger Muller counter, because they are so fast and they are used for pulsed neutron sources. So a silver activation counter has been constructed by plastic scintillator plates along with silver foils for determination the neutron yield of a 2.48 kJ plasma focus device, SBUPF1. This counter was calibrated by source removal method with an Am-Be 5 Ci neutron source which was placed above the anode of plasma focus device. Deuterium gas up to 8 mbar pressure was injected to this device, and the neutron yield produced by pulsed D-D fusion of plasma focus device was measured by the counter. The neutron yield of SBUPF1 in 8 mbar pressure was obtained (3.71 ± 0.32) × 10~7neutrons per shot. This result has relatively agreed with the neutron yield measured by silver activation Geiger counters.
