Primary scintillation characteristics of Ar+CF4 gas mixtures excited by proton and alpha particles

Observation of strong wavelength-shifting in the argon-tetrafluoromethane system

“…The results obtained in this work may be compared with the ones obtained for Ar/CF 4 mixtures in a 9 MeV proton beam at 1 bar in Liu et al (2012). Little details are found there in regard to space charge, recombination and beam-induced scintillation and in fact the relative normalization of the visible/UV bands is not given either.…”

Enhanced light extraction efficiency of plastic scintillator by photonic crystal prepared with a self-assembly method

“…For the application in pulsed neutron/gamma mixed radiation field, thin sheet of plastic scintillator is required for the sake of achieving a better neutron-to-gamma sensitivity ratio. For other application such as particle identification based on the time-offlight [7], decay time measurement [8] excited by a single charged particle, a thin scintillator film to provide the start timing signal is preferred [9]. However thin sheet will lead to a rather low detection efficiency due to the weak luminescence.…”
