Magnetic spectrometry of high energy deuteron beams from pulsed plasma system

Abstract

A detailed and precise study of high energy deuteron beams from a plasma focus device shows that they follow a non-power law distribution, unlike most of the other works. This is in agreement with our previous studies using a direct and unambiguous diagnostic of the activation yield-ratio technique. It is possible that the E −n dependence effectively terminates at some maximum deuteron energy. The experimental results show that the spectrum increases to very high energies whereas the power law fit fails. A unique feature of the magnetic spectrometry experimental arrangement, in this work, is that the pinhole holder also functions as a Faraday cup for time-resolved measurements of the deuteron beam.

Time-resolved characteristics of deuteron-beam generated by plasma focus discharge

“…This is due to difficulties in the design of diagnostic techniques and detectors having sufficient temporal and spatial resolution to record the transient nature and wide energy range of the emitted ion-beam. Existing diagnostics techniques that are often used to measure the ion-beam characteristics are the Thomson parabola Spectrometer [ 16 ], Magnetic spectrometer [ 17 ], nuclear activation method [ 18 ], Faraday cup [ 19 , 20 ], biased ion collectors [ 21 ], solid state nuclear track detectors (SSNTDs) [ 22 ] and activation yield-ratio technique [ 23 ].…”

High efficiency focus neutron generator

“…The performance of plasma focus as a neutron generator, using the mentioned procedure in this paper for all known plasma focus devices, has been investigated. At the end 1.1×10 9 and 1.1×10 11 neutrons per second are produced by D-D and D-T reactions, respectively in the ENEA device with 1 Hz working frequency. Also 1.34×10 10 and 1.34×10 12 neutrons per second are produced by D-D and D-T reactions, respectively in the NX2 device with 16 Hz working frequency.…”

“…Moreover, the investigation of experimental spectra [7] shows that as the number of incident deuterons increase, the value of m decreases and the activity increases.…”

“…In this study, first the activity of a set of experimental spectra of deuteron produced by NX2 plasma focus device which has been measured by magnetic spectrometer [7] is calculated and then the optimizing conditions of 13 N production is investigated.…”
