	Due to the folded geometry of the linac, beam loss monitoring at the Facility for Rare Isotope Beams (FRIB) [1], especially for small losses, is extremely challenging in the low energy section of the linac. Fast detection is not required for slow/small beam losses, and we therefore propose thermometers installed in the cryomodules at potential hot spots, such as the locations upstream of solenoids. Cryogenic thermometry tests were implemented in the ReA6 cryomodule with heaters and RTD thermometers. The preliminary study shows that the 10 mK signal resolution of thermometers corresponds to ~5 mW heat power in 100 seconds, or ~1 W heat power in 10 seconds, which is sufficient to satisfy the requirement for small beam loss at FRIB.

Due to the folded geometry of the linac, beam loss monitoring at the Facility for Rare Isotope Beams (FRIB) [1], especially for small losses, is extremely challenging in the low energy section of the linac. Fast detection is not required for slow/small beam losses, and we therefore propose thermometers installed in the cryomodules at potential hot spots, such as the locations upstream of solenoids. Cryogenic thermometry tests were implemented in the ReA6 cryomodule with heaters and RTD thermometers. The preliminary study shows that the 10 mK signal resolution of thermometers corresponds to ~5 mW heat power in 100 seconds, or ~1 W heat power in 10 seconds, which is sufficient to satisfy the requirement for small beam loss at FRIB.
