## Work hours by group:

## In Summary:

- Large amount of work completed in all machines
- Most planned work related to major projects completed within shutdown period
- Booster shutdown was the tightest as usual
- LINAC “early” startup:
- Forces some job cancellations
- Some jobs put off until this shutdown

- Paul W. Sampson

## Some sore spots remain

- Some power outages continue to pose unforeseen complications
- PASS implications not always known:
- Not all appropriate devices on UPS or emergency power
- Some outages, such as building 911, must be more carefully planned to avoid last minute changes
- LIPA outages, especially BMMPS alternate feed can pose unique challenges
- AtR transformer work done late in the game, making the RHIC re-certification painful

- Paul W. Sampson

## Rescheduled work

- For the most part, the work rescheduled last shutdown will be done this shutdown
- RHIC Power supply upgrade, voltage monitor install
- Siemens Rectifier transformers
- Siemens Ripple filter install
- Booster MMPS AB software install
- Many of the smaller jobs were completed during Maintenances and Accesses

- Paul W. Sampson

##  Startup and testing:

- Remains a challenge
- Jobs running late
- Late arriving parts
- Checkout of supplies and Magnets – white sheets
- Dependant on outside forces, manpower
- Restoration from minimal power usage is more challenging
- Coordination with PE and Outside contractors
- Shift personnel

- Paul W. Sampson

- Revise Maintenance web page for increased utility *continuing*
