Summary, in English

A recently developed fast analysis technique utilizing a time of flight (TOF) telescope is demonstrated to obtain relevant quantitative data on material scintillation response to energetic He particles. With the superior energy resolution and fast response of the TOF telescope, the energy of individual particles before impinging on a scintillator crystal can be determined with a high count rate, allowing quantitative study of material performance over a continuous energy range in a relatively short time. Scintillation performance in terms of light output, nonlinearity and energy resolution in bismuth germanate (BGO) and europium-doped calcium fluoride (CaF2:Eu) crystals is demonstrated, and the corresponding energy resolution is compared with gamma-ray tests on the same crystals.
