Position sensitive silicon detectors are largely employed in the tracking systems of High Energy
Physics experiments due to their outstanding performance. They are currently installed in the
vertex and tracking part of the ALICE, ATLAS, CMS and LHCb experiments at LHC, the world’s
largest particle physics accelerator at Centre for European Nuclear Research (CERN), Geneva.
An upgrade of...

The leakage current of irradiated silicon sensors depends, among others, on sensor temperature and irradiation fluence. The temperature dependence is parameterized with the activation energy E$_g$ and the fluence dependence with the current related damage rate $\alpha$. The literature values for E$_g$ and $\alpha$ are obtained from previous measurements, but $\alpha$ is only measured directly...

The subject of the investigation arises from the intention to upgrade the beam loss monitoring system of the Large Hadron Collider by installation of semiconductor detectors located as close as possible to the superconducting coils of the triplet magnets and immersed in superfluid helium. For this, in-situ irradiation test of Si p-on-n detectors was carried out at 1.9K at CERN PS. The results...
