Response of a Li-glass/multi-anode photomultiplier detector to $\alpha$-particles from ${}^{241}$Am

Abstract

The response of a position-sensitive Li-glass scintillator detector to $\alpha$-particles from a collimated ${}^{241}$Am source scanned across the face of the detector has been measured. Scintillation light was read out by an 8 X 8 pixel multi-anode photomultiplier and the signal amplitude for each pixel has been recorded for every position on a scan. The pixel signal is strongly dependent on position and in general several pixels will register a signal (a hit) above a given threshold. The effect of this threshold on hit multiplicity is studied, with a view to optimize the single-hit efficiency of the detector.
