Managing SiPM with a front-end electronics to be able to work in photon counting and charge integration.
FluChe is an acronym for "Fluorescence and Cherenkov light detection" with SiPM for space applications.
Astroparticle and High Energy Astrophysics space missions measuring extensive air showers produced
by cosmic rays and neutrinos in atmosphere require detection of very faint and intense UV light.
Characteristics of the new generation of SiPM (Silicon PhotoMultiplier) are potentially right for this
purpose. Their high intrinsic gain, low power consumption, low weight and robustness against
accidental exposure to light are particularly important for spaceborn multipixels imaging cameras.
Their high-performance detection makes them promising for photon counting, where extreme
photodetector sensitivity is needed, as well as for charge integration, where the total amount of charge
in the signal is required.
The capability to operate SiPM contemporarily in photon counting and in
charge integration is strictly dependent indeed by the design of the front-end electronics. In this
context, the challenge is to find the right balance and a feasible solution for managing SiPM with a
front-end electronics to be able to work, contemporarily and efficiently, in photon counting and charge
