An ultra-low current sensing digitizer circuit was designed for radiation monitoring for personnel and environmental safety at CERN. The Ultralow Picoammeter 2 (Utopia 2) ASIC includes some key functionalities like on-chip active leakage current compensati ...
An ultra-low leakage current Application Specific Integrated Circuit (ASIC) called Utopia (Ultralow Picoammeter) has been designed and fabricated in AMS 0.35 mu m CMOS, in order to be used as the front-end for ionising radiation monitoring at CERN. It is b ...
An intercomparison of the performances of active neutron detectors was carried out in pulsed neutron fields in the new HiRadMat facility at CERN. Five detectors were employed: four of them (two ionization chambers and two rem counters) are routinely employ ...
