Energy spectra and space resolved measurements of fusion reaction protons from plasma focus devices

Abstract

Methods for ion detection with high spatial and spectral resolution in the energy range 70 keV≤Ed≤5 MeV were developed and applied at plasma focus facilities. Particularly, the fusion reaction protons of the D(d,p) T reaction were studied. Nuclear track detectors LR115A, CR-39, and CR-39/PM355 with aluminum foil filters in front were used and calibrated using a Thomson analyzer. The influence of the azimuthal magnetic field on the trajectories of the charged particles was calculated using an ion optical code.
