Scintillating Screens Investigations with Proton Beams at 30 keV and 3 MeV

Abstract : Luminescent screens hit by accelerated charged particle beams are commonly used as beam diagnostics to produce a visible emitted light, which can be sensed by a camera. In order to investigate the characteristics of the luminescence response of several scintillators, the beam shape and the observation of the transverse position, experiments were done with different low intensity proton beams produced by two different test benches. This study is motivated by the need to identify scintilla-tor materials for the development of a 4-dimensional emittancemeter which will allow the characterization of the beams, in particular the emittance measurement (size, angular divergence). This paper describes the experimental setups and our investigations of the optical properties of various scintillating materials at two different proton beam energies respectively about 30 keV and 3 MeV. The light produced by these screens is characterized by yield, flux of the emitted light versus the beam intensity, time response, and long life-time and they are compared.
