In this paper we investigate the impact of the single-cell signal response on the timing resolution capabilities of a silicon photomultiplier coupled to a slow scintillator such as LYSO. At FBK, we produced SiPMs featuring different layout configurations and, as a consequence, different values of the parameters composing the equivalent circuit. All the devices were coupled to Teflon-wrapped LYSO crystals and both energy and timing properties were analyzed. The study evidences that it is possible to strongly enhance the timing performance by a careful optimization of the sensor layout.

Abstract

In this paper we investigate the impact of the single-cell signal response on the timing resolution capabilities of a silicon photomultiplier coupled to a slow scintillator such as LYSO. At FBK, we produced SiPMs featuring different layout configurations and, as a consequence, different values of the parameters composing the equivalent circuit. All the devices were coupled to Teflon-wrapped LYSO crystals and both energy and timing properties were analyzed. The study evidences that it is possible to strongly enhance the timing performance by a careful optimization of the sensor layout.
