Once DC Power finished inspecting the ArcA box supply and handed it back to ops, there was concern from both operations and optics that cycling the entire west arc box supplies and all trims carried a significant risk of completely throwing off orbits and requiring time-consuming re-tuning of the main machine. As a sanity check, cycled only the ArcA box supply twice and checked D beam orbit. Orbit reproduced well up to AE02 (5th pass separator has not been phased yet, so losing beam here is expected), so we will heed the advice of the beam transport experts and resume the Hall C pass change.

Noticed communication for the new ARC10 Magnet Thermal Interlock Chassis installation was not working. Went out an confirmed the chassis heartbeat was working. Upon futher discussion we asked the crew chief for permission to check the functionality of the chassis. After approval was given we ramped down ARC10 and removed the klixon status connection. The chassis functioned as expected and interlocked ARC10. ARC10 was brought back up and cycled.

IONTG01 Card Ch#1 tripped leading up to the FSD card issue over the weekend. The card had previously been replaced, but the new card began showing higher noise levels than the original. We replaced it with another spare card, and it is now operating as expected. We will continue to monitor its performance.

LERF: OM219 (Lab 6) was reading low and triggered an alarm. We recalibrated the sensor and returned it to service. Since the backup sensor, OM220, is currently bypassed, we staged the portable unit in the lab to provide local alarm and ODH coverage in the event OM219 fails again.”
