Radiation Hardness Studies for High-Energy Phyisics and Space Missions

Radiation hardness of silicon pixel sensors and other electronic devices are being carried out using the Beam Transfer Line (BTL) of the Bern medical cyclotron, in collaboration with the LHEP ATLAS group. A specific irradiation apparatus was developed and constructed. The device under test (DuT) can be located in vacuum or in air. Flat beams of different sizes can be realized and monitored on-line by means of the UniBEaM and other detectors. The extracted current is continuously measured to assess the dose delivered to the DuT. For beams extracted into air, several DuTs can be located in a remotely controlled stage that can be operated to optimize irradiation.
