Abstract

Abstract. Dense Plasma Focus machine may be suitable for fusion first wall studies and its related material researches. As is well-known plasma focus devices are sources of high energy ions, electrons, x-rays and neutrons and intense bursts of fast plasma streams. In this paper, experimental measurements of neutron emission and hard x-ray emission from the plasma focus device are presented. The measurement of neutron and hard x-ray emission is studied using silver activation counter detector with two different dimensions Pb shielding and two scintillator photomultiplier detector systems. The research paper reported that the experimentally detected neutron emission in the radial direction where focus occurs also evaluated neutron fluency at different distances. The results show that neutron emission with different intensities and pulse width. Silver detector registered neutrons in the range 106-107 n/shot in the radial direction. The maximum neutron yield is 1.7×107 neutrons per shot.   

Key words: neutron yield, plasma focus, X-ray, shielding, silver foil, photo multiplier tube.
