A linear power supply circuit was designed for long runs with highly sensitive particle physics experiments, such as rare event searches with bolometric detectors. The circuit accepts unregulated power supply voltages up to about ±20 V and gives at the output very low noise, high stability voltages, whose values can be tuned between ±2:5 V and ±11:25 V. The rated current at the output is 4 A. The...
The CLARO is an ASIC for single photon counting with pixellated photomultipliers, designed to sustain a high counting rate at low power. It was primarily developed to readout multi-anode photomultipliers (Ma-PMTs) in the upgraded LHCb RICH detectors at the LHC. The first four-channel prototype, named CLARO-CMOS, was realized in a 0.35 µm CMOS technology, demonstrating the capability to count single...
We present a Bias Generator System designed for Large Mass Bolometric Detectors. The bias current, 100 pA ÷ 200 pA range, for these detectors is provided by large value resistors, that can be located at cold or at room temperature. To improve the precision and the stability of the bias current we developed a system based on a custom resistive network to take advantage of the good tolerance ratio and...
The ring imaging Cherenkov (RICH) detector at LHCb is now read out by hybrid photon detectors. In view of its upgrade, a possible option is the adoption of the flat-panel photon multiplier tube (PMT). An important issue for good reconstruction of the Cherenkov rings is a negligible level of crosstalk. We have experimentally studied the crosstalk from the 16 × 16-pixels Hamamatsu H9500 PMT. Results...
