Body: 

RM16 probe 2 (neutron) was replaced due to spiking in an effort to isolate the cause. Possible transients in the AC power or probe failure could be the issue. Probe will be monitored until it is removed for calibration.

Body: 

SSG with RF Group performed LOTO of 53 RF zones in the CEBAF.
In addition 1L08, 1L09 & 1L26 in the North Linac were HEC LOTO-ed by RF Group.
As planned 1L08 was LOTO-ed at MDP.
Due to failure of the locking mechanism on the CPS circuit breaker in zone 2L05 LOTO was installed on the upstream MDP.
All other zones were locked out at CPS.

It's in the tunnel so we couldn't investigate. For now, SSG has calibrated the monitor and they are watching it's signal.

Received a rad alarm from the PSS console. A liveplot showed the spiked dose rate signal, but it soon returned to normal levels. This particular monitor is a recent known issue. RadCon has been made aware as they are performing calibrations today. They plan to swap this monitor and see if this issue persists.
