ROC chips for imaging calorimetry at the International Linear Collider
2014
Imaging calorimetry at the
International Linear Colliderrequires highly granular and innovative detectors. Technological prototypes have been built and tested under the
CALICEcollaboration framework and FP6 EUDET, FP7 AIDA European programs. These prototypes are readout by multi-channel chips named SKIROC2, SPIROC2 and HARDROC2, designed by the IN2P3 OMEGA group in AMS SiGe 350 nm technology. In this presentation, the ASIC architectures and test results on
test benchand at system level will be described as well as first results of
test benchmeasurements performed on HARDROC3, which is the first of the ``3rd generation'' chip to be submitted and where the 64 channels are handled independently to perform
zero suppresson chip.
