Abstract

The search of new efficient scintillators can be simplified by the application of ion beams. The beam flux density of the order magnitude 1012–1014 ions/cm2sec can be easily achieved. The light yield visualization takes place even for weak scintillators as PbF2 under excitation by such beams. The light response of crystals for ion beams with E0 = 1–2 MeV is not connected with the Cherenkov's radiation. Ion excitation enables one to find the crystals with surface scintillation. Measurement were performed by means of 0.15–2.0 MeV H+, D+ and 4He+ ions with current 0.1–10 nA. Quantitative values of the light yield for the cubic phase of monocrystal PbF2 in random and channeling were obtained. Restrictions of the technique applicability are discussed.
