Description
• Egyptian Atomic Energy Authority – Plasma Focus device 1 (EAEA-PF1) was successfully redesigned in terms of its electrode system material and dimensions, insulator shape and the energy storage bank to investigate the best plasma focus action.
• A simple-to-perform technique was applied to investigate the distribution of the azimuthal magnetic field induction and the induced magnetic force acting on the plasma current sheath.
• The redesigned device can be efficiently used in many important applications including Controlled Fusion and working as Neutron and X-ray Source.
• Plasma Focus (PF) devices are considered as one of the most effective sources of pulsed neutron emission which is relevant for controlled fusion.
• Using deuterium as the filling gas, fast neutrons with energy of around 2.5 MeV and energetic protons with the energy of around 3 MeV are produced from PF devices [1].
• A passive radioactive source of fast neutrons with similar energy emits continuously, causing inconveniences in handling and storing. In turn, PF generators do not have activation problems for storage and handling [2].
• PF devices have the advantage of the ability to operate with some other types of gases or gas mixtures which makes it a generator of a pure x-ray radiation (not accompanied by the neutrons) [3].
• Redesigning the device was the first step to be able to use it in these applications.
• X-ray and Neutron yield had to be improved to make the device applicable in these applications which couldn’t be done without modifying the device.
