Detection of minimum-ionizing particles and nuclear counter effect with pure BGO and BSO crystals with photodiode readout

Abstract

) crystals coupled with silicon photodiodes have been used to detect minimumionizing particles(MIP). With a low noise amplifier customized for this purpose, the crystals can detect MIPs with an excellent signalto-noise ratio. The nuclear counter effect is also clearly observed and measured. Effect of full and partial wrapping of a reflector around the crystal on light collection is also studied.
