Gain Stabilization of SiPMs and Afterpulsing

, 2019
The gain of silicon photomultipliers increases with bias voltage and decreases with temperature. To operate SiPMs at stable gain, the bias voltage can be readjusted to compensate for temperature changes. We have tested this concept with 30 SiPMs from three manufacturers in a climate chamber at CERN varying the temperature from 1 degree C to 48 degrees ...

The SiPM-on-tile system of the CMS HGCAL [PDF]

EPJ Web of Conferences
For the CMS High-Granularity Calorimeter (HGCAL) for HL-LHC, scintillator tiles, readout with individual on-tile silicon photomultipliers (SiPMs), will be used where the radiation levels are expected to be less than 5 × 1013 neq/cm2.

Time and charge characterization of Hamamatsu Photonics silicon photomultipliers

EPJ Web of Conferences, 2014
Two Hamamatsu Photonics silicon photomultipliers (SiPM) with same cell size 50×50 µm2 and different sensitive area (1×1 mm2 vs. 3×3 mm2) have been characterized in charge and time by means of a 409 nm pico-laser.

FLC−SIPM: Front-End Chip for SIPM Readout for ILC Analog HCAL

, 2005
An integrated front-end chip has been developed to readout the Silicon PM for the ILC analog hadronic calorimeter. It is built around a variable gain low-noise preamplifier followed by a variable peaking-time shaper (20-200 ns), track and hold and multiplexed output.
