Description
Skipper-CCD technology currently leads the search for light dark matter in underground experiments (SENSEI and DAMIC), and for fractionally charged particles at nuclear reactors (CONNIE and Atucha II). By applying Skipper technology in silicon CCD, sub-electron noise levels can be achieved through multiple non-destructive measurements of the same charge. The cost to pay are longer readout times, which in some cases can extend to several hours. In this work, we evaluate the impact of a real-time parametric hypothesis test to reduce the number of samples required to discriminate between empty and occupied pixels. We analyze how the resulting reduction affects known background contributions, such as amplifier-induced light during sampling and dark current. The implementation of this approach is studied through simulations of the sensor’s continuous readout. The results demonstrate substantial reductions in readout time and, consequently, in the aforementioned background contributions. We also examine how this reduction would affect existing results in searches for dark matter and exotic particles in neutrino physics.
