A gas proportional scintillator counter for thermal neutrons instrumentation
Manzin, G.; Guerard, B.; Fraga, F. A. F.; Margato, L. M. S.A gaseous scintillation detector consisting of a 3He+CF4 filled MSGC detector coupled with an optical readout has been investigated for an application for high-resolution and high counting rate position-sensitive neutron detector. Measurements of the photons' emission as a function of the gas mixture have been carried out indicating that filling the detector with 3He+CF4 is a very good choice also from the poin...
Time analysis of the light pulses on gaseous active scintillators using GEMs wi...
Margato, L. M. S.; Fraga, F. A. F.; Fetal, S. T. G.; Fraga, M. M. F. R.; Marques, R. Ferreira; Policarpo, A. J. P. L; Guerard, B.; Manzin, G.The time structure of light pulses from GEM detectors operated in scintillation mode with He/CF4 mixtures, previously used with integrating readout devices for neutron detection, has been investigated. A system using photomultipliers (PMs) and charge preamplifiers coupled to a fast digitizer has been used to measure simultaneously both the charge and light signals of the avalanches and the dependence of these s...
