Description
The Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) is dedicated to studying the properties of strongly interacting matter under extreme conditions. Operating with the SIS100 synchrotron, which accelerates protons up to 29 GeV and heavy ions up to 10 GeV/nucleon, the experiment will reach unprecedented interaction rates of up to 10 MHz. These extraordinary beam intensities and the resulting extreme particle fluxes strictly demand highly radiation-hard detector technologies. Under these harsh conditions, precise online monitoring of instantaneous luminosity and beam background is critically important to ensure safe and stable data taking. Drawing on the extensive experience of the Institute of Nuclear Research (NASU) in the field of metal foil detectors (MFD), the technology for which was utilised in the development of Radiation Monitoring System (RMS-R3) for the LHCb experiment, we present the development of a novel monitoring system adapted for the CBM setup.
The primary objective of this work was to adapt the established MFD technology to the specific geometric, constraints and severe radiation environment of the CBM setup. The methodology included 3D modeling of the detector modules, Monte Carlo simulations to estimate theoretical sensitivity, and LTspice simulations to optimize the front-end electronics. Based on these designs, functional prototypes were successfully assembled. Comprehensive laboratory testing was conducted, including baseline stability measurements and detector response evaluation using a radioactive source. The obtained results confirmed the operability, high precision, and stability of the new modules, proving that the developed MFD-based prototypes offer a reliable solution for online radiation monitoring in the CBM experiment.
