Characterization of Radio-Photo-Luminescence (RPL) Dosimeters as Radiation Monitors in the CERN Accelerator Complex

Abstract

Dosimetry is a crucial activity in irradiation campaigns to qualify electronics and materials to operate in radiation environments. In addition, it also provides means of monitoring radiation levels in accelerator environments to prevent radiation damage to the machines and improve system lifetime. Therefore, this work provides the characterization of radio-photo-luminescence (RPL) glass dosimeters as a high-level radiation monitor to be used in the mixed radiation fields observed in CERN’s accelerator environment as well as in irradiation campaigns for the qualification of electronic components and materials. Here, two methods to improve the measured dose are presented, one for the correction due to the fading of the RPL dosimeters (RPLDs), where an improvement of over 40% of the measured to the expected dose could be achieved, and one method that corrects the measured dose in mixed-particle fields to dose in water or air.
