System Modelling and Improvements of a Mixed Analog Digital Chip for Ionization Chamber Readout in Static and Pulsed Fields

One of the biggest challenges for radiation monitoring at CERN is the presence of highly pulsed fields, in addition to quasi static ones. In order to have a ubiquitous monitoring system, one must be able to accurately detect currents from the tens of femto- to the hundreds of micro-amperes, as well as highly pulsed currents up to 500𝑛𝐶. The aim of the master thesis is to improve the current, ASIC-based electronic front-end (ACCURATE) in the pulsed regime without modifying its internal design, nor affecting significantly the quasi static regime’s performance.
