Upgrade of the ALICE TPC FEE online radiation monitoring system

This paper presents the radiation monitoring system on the Readout Control Unit (RCU) of the the ALICE TPC Front End Electronics. In Run 1, Single Event Upsets (SEUs) in the configuration memory of an SRAM based FPGA were counted, and the results from different run periods with stable beam condition...

description This paper presents the radiation monitoring system on the Readout Control Unit (RCU) of the the ALICE TPC Front End Electronics. In Run 1, Single Event Upsets (SEUs) in the configuration memory of an SRAM based FPGA were counted, and the results from different run periods with stable beam conditions are presented. For Run 2, a new RCU, the RCU2, has been designed in order to achieve higher data readout rates and increase radiation tolerance. The RCU2 also includes a new radiation monitor solution with increased sensitivity, which is based on counting the number of SEUs in dedicated SRAM memories. The paper presents this new solution together with the results from the targeted irradiation campaigns.
