Measuring Large Energy deposition with HV-MAPS — •Danish Alam for the HD-HVMAPS collaboration — Physikalisches Institut, Heidelberg University

In high-energy physics experiments, the increasingly challenging physics demands high-rate detectors with excellent spatial and time resolution. High Voltage - Monolithic Active Pixel Sensor (HV-MAPS) fabricated in HV-CMOS processes provides fast charge collection via drift and enables the implementation of readout and the sensitive volume on the same die. Currently, the first tracking detector utilizing ultra-thin HV-MAPS chips is under construction for the Mu3e experiment.

At present, typical HV-MAPS detectors can measure energy depositions of the order of several 10 keV before the in-pixel charge-sensitive amplifier suffers saturation effects. The primary goal of the test chip Run2021V3 is to extend the measurable range and improve the precision of the measurements, which will allow detailed studies of the energy deposition of traversing particles, e.g., for particle identification. In the scope of this talk, the first characterization results of the Run2021V3 prototype will be presented.
