Extensive studies of effects of annealing at 60°C on charge collection efficiency were made during development and production of sensors for ATLAS ITk strip detector. After irradiation with neutrons or low energy protons, at bias voltages below ~ 900 V, “typical” annealing behaviour was observed: beneficial effect of short term annealing was followed by a drop of charge collection efficiency...

To face the higher levels of radiation due to the 10-fold increase in integrated luminosity during the H-L LHC, the CMS detector will replace the current endcap calorimeters with the new High-Granularity Calorimeter (HGCAL). The electromagnetic section as well as the high-radiation regions of the hadronic section of the HGCAL (fluences above 1.0e14 neq/cm2) will be equipped with silicon pad...

Organic technologies are of active scientific interest due to their tuneable, scalable, and cost-effective nature. I will present radiation sensors based on organic semiconductor technology, particularly applications related to detection of hadronic radiation consisting of α radiation and thermal and fast neutrons. Neutron detection is useful in various fields, from fundamental particle and...
