Description

A new in-flight separator Super-FRS is under construction at FAIR/Darmstadt. Ion rates up to 3 x 1011 238U/spill demand an adaptation of detectors to a high radiation environment. A test experiment to investigate the radiation hardness of polycrystalline diamond detectors(pcCVD) was performed at the LNS-INFN in Catania using a 12C beam at 62 MeV/u and intensities of up to 1.5 pnA. The setup consisted of pcCVD strip detectors to measure the beam profile, a single crystal diamond detector to calibrate the IC working in current mode as a beam intensity monitor and a pcCVD sample to be irradiated. The IC used was designed for FAIR and showed a stable counting rate allowing us to calibrate and perform beam intensity measurements with it. The results showed no decrease of the signal quality before and after the irradiation of 3.5 MGy. A second experiment at GSI aimed at a very precise calibration of this IC using a plastic scintillator as reference, achieving a relative precision below 1%.
