was selected for the cover page of Sensors, Volume 24, Issue 5!

It is about:
Correcting the Non-Linear Response of Silicon Photomultipliers

Silicon PhotoMultipliers (SiPMs) are pixelated photo-detectors operating in Geiger mode for single photon detection. They are commonly used in applications requiring high spatial resolution like high-energy physics and medical imaging, as well as for their high photo-detection efficiency in astrophysics, space detectors, and LIDAR systems. SiPMs have a non-linear detection range from one to several thousand photons. We have devised a method to correct the non-linear response of SiPMs using only SiPM measurements, independent of light source knowledge or linearity. The method involves uniformly illuminating the SiPM surface with two tunable light sources, LED and laser, of varying amplitude and arrival time. Through this technique, we can effectively correct the SiPMs' non-linear response and expand the linear dynamic range by over tenfold.

First testbeam of the year

Last week we had our first testbeam of the year. This time, we took data in area T24 of the DESY II test beam facility to test Low Gain Avalanch Diodes (LGADs) at different voltages and under different beam incidence angles.
