“…Progress in such research has stimulated ion-beam emission studies in areas of material science, the ion-beam source motivating research applications in for instance surface modification [ 32 , 33 ], ion implantation [ 34 , 35 ], thin-film deposition [ 36 , 37 ], semiconductor doping [ 38 ], synthesis of nanoparticles [ 39 ], amorphization of silicon [ 40 ], Nanostructuring of FePt thin films [ 41 ] and formation of nanoparticle [ 42 ]. While many ion-beam measurement and diagnostic techniques have been developed, most particularly in seeking to characterize ion-beam emission, challenges continue to remain in clarifying the various emission complexities.…”

The plasma focus device discussed herein is a Z-pinch pulsed-plasma arrangement. In this, the plasma is heated and compressed into a cylindrical column, producing a typical density of > 1025 particles/m3 and a temperature of (1–3) × 107 oC. The plasma focus has been widely investigated as a radiation source, including as ion-beams, electron-beams and as a source of x-ray and neutron production, providing considerable scope for use in a variety of technological situations. Thus said, the nature of the radiation emission depends on the dynamics of the plasma pinch. In this study of the characteristics of deuteron-beam emission, in terms of energy, fluence and angular distribution were analyzed. The 2.7 kJ plasma focus discharge has been made to operate at a pressure of less than 1 mbar rather than at its more conventional operating pressure of a few mbar. Faraday cup were used to determine deuteron-beam energy and deuteron-beam fluence per shot while CR-39 solid-state nuclear track detectors were employed in studying the angular distribution of deuteron emission. Beam energy and deuteron-beam fluence per shot have been found to be pressure dependent. The largest value of average deuteron energy measured for present conditions was found to be (52 ± 7) keV, while the deuteron-beam fluence per shot was of the order of 1015 ions/m2 when operated at a pressure of 0.2 mbar. The deuteron-beam emission is in the forward direction and is observed to be highly anisotropic.

“…The device is particularly interesting due to its special characteristic as intense pulsed sources of X-rays, ions, electrons and neutrons (deuterium filling) [2][3][4][5]. The early research was concentrated on the neutron emission [6,7] and yet in recent years, there is abrupt growth of researcher's interest in utilized plasma focus for its application in surface modification [8], ion implantation [9] and thin film deposition [10].…”

Diagnostics of ion beam emission from a 3 kJ Mather-type plasma focus device have been performed for deuterium discharge at low pressure regime. Deuterium plasma focus was found to be optimum at pressure of 0.2 mbar. The energy spectrum and total number of ions per shot from the pulsed ion beam are determined by using biased ion collectors, Faraday cup, and solid state nuclear track detector CR-39. Average energy of the ion beam obtained is about 60 keV. Total number of the ions has been determined to be in the order of 10 11 per shot. Solid state nuclear track detectors (SSNTD) CR39 are employed to measure the particles at all angular direction from end on (0˚) to side on (90˚). Particle tracks are registered by SSNTD at 30˚ to 90˚, except the one at the end-on 0 ˚.
