Recent developments of CERN RD39 cryogenic tracking detectors collaboration

CERN RD39 Collaboration is working on radiation hard cryogenic silicon detectors, for environments such as at the Super-LHC. A promising technique for the operation of low temperature detectors and diodes is the current injection of pre-irradiated samples (CID). A new setup, based on the Cryogenic Transient Current Technique (C-TCT), has been built to characterize Si samples (CCE). In addition, we report here some preliminary measurements for the evaluation of laser and plasma-cut sensors developed for edgeless detectors, for which the sensitive area should extend to a few μm from the physical border.
