A time resolution study with a plastic scintillator read out by a Geiger-mode Avalanche Photodiode

Abstract

a b s t r a c tIn this work we attempt to establish the best time resolution attainable with a scintillation counter consisting of a plastic scintillator read out by a Geiger-mode Avalanche Photodiode. The measured time resolution is inversely proportional to the square root of the energy deposited in the scintillator, and scales to s ¼ 18 ps at 1 MeV. This result competes with the best ones reported for photomultiplier tubes.

A multi-purposed detector with silicon photomultiplier readout of scintillating fibers

“…A low-noise amplifier circuit (noise level o 10 mV peak-to-peak) was developed and optimized for low light collection, based on the Mini-Circuits MAR-6 gain block device [11].…”

High precision measurement of positron time in MEG upgrade

“…SiPM generally has a good timing response by its simple structure. The good performance of the single counter was already proved by the detector at the PSI µSR facility [6] and in our previous work [4].…”

30-ps time resolution with segmented scintillation counter for MEG II

“…This approach is a contrast to that with Cherenkov counters which rely on the small but prompt signal detected with excellent time-response photodetectors such as microchannel plate photomultipliers. A resolution of σ = E 18 ps MeV 0.5 0.5 , where E is the energy deposited in the scintillator, was achieved in [3] with a × × 3 3 2mm 3 counter. A better resolution of 15 ps MeV 0.5 is indicated to be achievable in [4] by scaling the sensor coverage effect.…”
