Description

A set of unirradiated LGADs from the HPK prototype 2 run for HGTD were used to determine the impact ionization parameters for silicon, particularly in the electric field range of ∼30 V/μm which is of interest for LGADs. The parameters' dependence on temperature was determined. Their validity on irradiated sensors up to 2.5E15 cm$^{-2}$ was also tested.
