Abstract
Methods for suppressing optical crosstalk between cells in silicon photomultipliers were experimentally studied. The mechanisms of optical crosstalk suppression are considered and the extent of the effect of each type is shown. A method for separating photosensitive cells, based on etching of V-shaped grooves is studied. The principal possibility of decreasing optical crosstalk between cells from 20−40 to 0.1−0.7% is shown in the overvoltage range of 2−5 V, respectively.
