摘要:
Plasma focus (PF) is a rich source of pulse X-ray and neutron emission. The measurement and analysis of X-ray and neutron emission from a 2.2 kJ PF device has been carried out using photo multiplier tube (PMT), PIN diode, pinhole camera, vacuum photodiode (VPD) and neutron bubble dosimeter. The soft X-rays are more or less emitted in multiple pulses. Hot spots are found to be present in the X-ray emitting zones of pinched plasma column. The neutron emissions are more in numbers as well as more energetic in axial direction as compared to the radial one. The neutron's anisotropic emission may be influenced by beam-target mechanism.
