Radiation study of FPGAs with neutron beam for COMET Phase-I.

The COMET Phase-I experiment plans to search for muon to electron conversion. In order to get a good signal-to-noise ratio and time resolution, all the front-end readout boards are installed near the detector region where the radiation level is high. The radiation effects, in particular from neutrons, onto FPGA hardware will be a severe problem. We developed high reliable firmware with auto-recovery schemes for three different series of FPGAs, and evaluated them with a neutron beam. In these tests, soft error rates were measured and good performances of the schemes were demonstrated. [ABSTRACT FROM AUTHOR]
