In paper we present the results from distributed optical fiber radiation sensing measurements at the 'Cern High energy AcceleRator Mixed field facility', CHARM. The measurements have been carried out on a multimode (MM) radiation sensitive P-doped optical fiber. The distributed measurements have then been carried out by means of an Optical Time Domain Reflectometry (OTDR) system using different interrogation and acquisition parameters to understand their influence on the results. We demonstrate the possible localization of the total dose with meter scale spatial resolutions and dose resolution down to 10-15 Gy. The obtained distributed dose profiles are validated by the benchmark with RadFET dosimeters and appear very promising for high energy accelerators and physics experiments as well as for industrial applications.

Abstract

In paper we present the results from distributed optical fiber radiation sensing measurements at the 'Cern High energy AcceleRator Mixed field facility', CHARM. The measurements have been carried out on a multimode (MM) radiation sensitive P-doped optical fiber. The distributed measurements have then been carried out by means of an Optical Time Domain Reflectometry (OTDR) system using different interrogation and acquisition parameters to understand their influence on the results. We demonstrate the possible localization of the total dose with meter scale spatial resolutions and dose resolution down to 10-15 Gy. The obtained distributed dose profiles are validated by the benchmark with RadFET dosimeters and appear very promising for high energy accelerators and physics experiments as well as for industrial applications.
