With the HL-LHC upgrade of the ATLAS detector, the surface of the ATLAS pixel detector will increase from 2 m² to approximately 13 m² . Therefore, commercial CMOS processing lines offering high production throughput at comparatively low costs represent an attractive option for such large-area detectors. Further benefits originate from multiple metal layers, metal–insulator–metal capacitors,...
This contribution will be focused on the lab performance evaluation of the electrical parameters before irradiation of three different blocks of the RD50-MPW2 device, the 8 by 8 matrix of depleted monolithic active pixel sensors, the bandgap voltage reference and the SEU (Single Event Upset) tolerant memory array. The RD50-MPW2 was developed in the framework of the RD50 collaboration and...
Digital calorimetry relies on a highly granular detector where the cell size is sufficiently small so that only a single particle in a shower enters each cell within a single readout cycle. The DECAL sensor, a depleted monolithic active pixel sensor (DMAPS), has been proposed as a possible technology for future digital calorimeters. A DECAL sensor prototype has been designed and fabricated in...
The data acquisition (DAQ) system used to read out and characterize the two versions of RD50 HV-CMOS prototype chips (MPW1 and MPW2) is based on the CaRIBOu (Control and Readout Inner tracking Board) system. CaRIBOu is a widely used versatile DAQ platform to characterize pixel detectors and ASICs, such as CLICpix2, C3PD and others. It consists of a system-on-chip board (e.g. Xilinx ZC706), a...
We had p-type HV-silicon JFETs, fabricated at Brookhaven National Laboratory, irradiated with neutrons at the Triga reactor in JSI, up to a fluence of 1.5e15 neq/cm2. Most notably, output characteristics show a dramatic increase of the drain saturation voltage with the irradiation. By means of TCAD simulations, which used the Perugia radiation damage model, we are explaining this effect as due...
