  1. WP8.5.2 Electronics Options • T2K ND280 TRIP-t • DRS4(5) • EASIROC/MAROC DRS4

  2. AIDA WP8.5.2 light yield estimates

  3. EASIROC Description • Number of channels: 32 • Analogue core : • Internal input 8-bit DAC (0-4.5V) for individual SiPM gain adjustment • Individually addressable calibration injection capacitance • Energy measurement : 14-bit dynamic range • 2 tuneable gains followed by 2 adjustable shapers • Analogue memory (Track & Hold cell) for low gain and high gain • Common 10-bit DAC for threshold adjustment • Variable shaping time: from 25 ns to 175 ns • from 160 fC 320 pC (ie. 1 pe 2000 pe @ SiPM gain = 106) • pe/noise ratio : ~10 @ SiPM gain 106 • Trigger output • pe/noise ratio on trigger channel : ~ 25 • Fast shaper : ~15ns • Trigger on 50 fC (ie. 1/3 pe @ SiPM gain = 106)
