HRTEM, LA-ICP-MS and DLTS techniques were employed to characterize several types of B-doped silicon diodes after irradiation with hadrons. The HRTEM results on LGAD samples irradiated with 1019cm-2 show that there is a preferential grouping of defects along tracks normal to the film surface. We will present the LA-ICP-MS technique, recently installed in NIMP, with which we could estimate the...

P-type silicon exposed to high radiation environment undergoes an apparent deactivation of the boron dopant – known as the so-called Acceptor Removal Effect (ARE). To investigate the impact of high energy electrons of different fluences on the ARE, p-type Si diodes, irradiated at the CLEAR facility at CERN with 200 MeV electrons as well as sensors irradiated with 5.5 MeV electrons at...

In this work the Thermally Stimulated Current (TSC) technique has been used to investigate the properties of the radiation induced BiOi defect complex by 23 GeV protons, including activation energy, capture cross section, defect concentration as well as the annealing behavior. At first isothermal annealing (at 80 °C for 0 to 180 minutes) followed by isochronal annealing (for 15 minutes between...

This presentation deals with observation of an increase of quantum yield at lover photon energy in highly irradiated Si in comparison with less or non-irradiated Si. The effect was observed in neutron irradiated Si to the... -

The time stability of a single crystal diamond radiation detector in response to alpha particle irradiation is studied in this work. A diamond detector is fabricated from a free-standing single crystal diamond plate and is packaged for the alpha irradiation studies. The detector under the bias voltage of +70 V is kept under constant alpha irradiation from a mixed α-source having major activity...

Owing to their low dark current, high transparency, high thermal conductivity and potential radiation hardness, there is a special interest in silicon carbide devices for radiation monitoring in radiation harsh environments or operation at elevated temperatures.
