Small plasma focus as neutron pulsed source for nuclides identification.
In this paper, we present preliminary results on the feasibility of employing a low energy (2 kJ, 31 kV) plasma focus device as a portable source of pulsed neutron beams (2.45 MeV) generated by nuclear fusion reactions D-D, for the "in situ" analysis of substances by nuclear activation. This source has the relevant advantage of being pulsed at requirement, transportable, not permanently radioac...
متن کاملA fast miniature plasma focus based compact and portable nanosecond pulsed neutron source
A low energy fast miniature plasma focus device ‘FMPF-1’ has recently been developed to be used as compact and portable nanosecond pulsed neutron source for field applications. The system operates in deuterium producing maximum neutron yield in the order of 10 neutrons/ pulse in 4� sr. at ~80kA peak discharge current. In the range of 4 to 7mbar distinct and sharp dip in the current derivative s...
متن کاملPulsed Plasma Thrusters for Small Satellites
Since the Russian launch of the Zond-2 satellite in 1964 there have been over fifty years of research dedicated to the understanding of the first electric propulsion device to be flown in space, the Pulsed Plasma Thruster. The Pulsed Plasma Thruster originates from the evolution of the vacuum arc switch, but due to its microsecond operation time, the internal dynamics and nature of operation ha...
متن کاملLENS: A New Pulsed Neutron Source for Research and Education
A new pulsed neutron source is under construction at the Indiana University Cyclotron Facility (IUCF). Neutrons are produced via (p,n) reactions by a low-energy proton beam incident on a thin beryllium target. The source is tightly coupled to a cold methane moderator held at a temperature of 20 K or below. The resulting time-averaged cold neutron flux is expected to be comparable to that of the...
متن کاملLow-Energy Plasma Focus Device as an Electron Beam Source
A low-energy plasma focus device was used as an electron beam source. A technique was developed to simultaneously measure the electron beam intensity and energy. The system was operated in Argon filling at an optimum pressure of 1.7 mbar. A Faraday cup was used together with an array of filtered PIN diodes. The beam-target X-rays were registered through X-ray spectrometry. Copper and lead line ...
