Under zero detector capacitance it has the equivalent 3000 electrons noise charge (FWHM) and pulse response total length 15 nS. The four-channel amplifier has dimensions 50x20x3 mm. 3 refs. %0Technical Report %NIFVE-ONF-89-231;Other: ON: DE92616771; TRN: SU9109390017414 %1 %CUSSR %Rhttps://doi.org/ Other: ON: DE92616771; TRN: SU9109390017414 INIS %GRussian
