Study of Diamond Detectors Spectrometric Response

Worldwide researches on Magnetic Confinement Fusion (MCF) are approaching to the final exam, namely ITER Project. The theoretical and experimental results of the last decades clearly show the complexity of the subject as well as the challenges in new technologies. Our group, with international collaborations, have conducted scientific research on plasma fusion diagnostics development.

Spectrometric measurements of fusion products under a high temperature and mixed radiation field require precise instruments that can withstand extremely high doses of radiation during a tokamak operation, while providing high-quality experimental data necessary for plasma physics research.

Upstanding crystal properties make a high-purity single crystal CVD diamond a major player in a number of the plasma diagnostics systems at ITER and other modern fusion facilities. The scientific research, with accompanying tests of diamond detector and related high-end electronics, are an ongoing activity of NZ61 department at IFJ PAN.

The time evolution of the energy spectra distortions partly depends on the charge collection efficiency as a function of temperature.
