DESCRIPTION:Speakers: Rudolph Rogly (CNRS)\nThe HKROC ASIC was originally 
 designed to readout the photomultiplier tubes for the Hyper-Kamiokande exp
 eriment. HKROC is an auto-triggered very versatile and innovative ASIC cap
 able of readout a large number of channels while meeting very stringent re
 quirements in terms of noise\, time & charge resolution while sustaining v
 ery high hit-rate and low-power consumption.\nEach HKROC channel features 
 a low-noise preamplifier and shapers\, a 10-bit successive approximation A
 nalog-to-Digital Converter (SAR-ADC) for the charge measurement (up to 250
 0 pC) and a Time-to-Digital Converter (TDC) for the Time-of-Arrival (ToA) 
 measurement with 25 ps binning. The key feature of HKROC is its “wavefor
 m digitization” capability: it dynamically opens acquisition windows for
  internal digitization. It enables new possibilities in terms of pulse-sha
 pe analysis and double pulse triggering with a low dead time (down to 10 n
 s)\, while preserving a very low power consumption compared to standard fl
 ash-ADC. Moreover\, HKROC is equiped with an adaptive readout which allows
  to cope with very high rate events such as close supernovae (Betelgeuse
 …) for neutrino based experiment.\nThe presentation will describe the AS
 IC architecture and the experimental results of the second HKROC prototype
  received in December 2022.\n\nhttps://indico.tlabs.ac.za/event/112/contri
