Detection of Liquid Xenon Scintillation Light with a Silicon Photomultiplier

We have studied the feasibility of a silicon photomultiplier (SiPM) to detect liquid xenon (LXe) scintillation light. The SiPM was operated inside a small volume of pure LXe, at -95C, irradiated with an internal Am α source. The gain of the SiPM at this temperature was estimated to be 1.8 × 10 with bias voltage at 52 V. Based on the geometry of the setup, the quantum efficiency of the SiPM was ...

The lower bound on the timing resolution of scintillation detectors.

The timing performance of scintillation detectors is ultimately limited by photon counting statistics. In fact, photon counting statistics form a dominant contribution to the overall timing resolution of many state-of-the-art detectors. A common approach to investigate this contribution is to calculate the variance in the registration times of individual scintillation photons within the photose...

Lower bounds on scintillation detector timing performance

Fundamental method-independent linuts on the timing performance of scintillation detectors are useful for identifying regimes in which either present timing methods are nearly optimal or where a considerable performance gain might be realized using better pulse processing techniques . Several types of lower bounds on mean-squared timing error (MSE) performance have been developed and applied to...

Development of a Compton camera for medical applications based on silicon strip and scintillation detectors

A Compton camera is being developed for the purpose of ion-range monitoring during hadrontherapy via the detection of prompt-gamma rays. The system consists of a scintillating fiber beam tagging hodoscope, a stack of double sided silicon strip detectors (90×90×2 mm, 2×64 strips) as scatter detectors, as well as bismuth germanate (BGO) scintillation detectors (38×35×30 mm, 100 blocks) as absorbe...
