RHIC (see attached slide)

- vacuum now better than pre-maintenance

- single-beam study on Friday was screwed up by not turning off continuous gap cleaning

- relies on collimators to remove kicked beam, which had been moved out

- single-beam test repeated at the end of this store around noon

- Angelika will try to come in for that

- continuous gap cleaning at 1 Hz will be turned on from the next store by default

STAR

- continuous gap cleaning: level of distortions acceptable at this intensity

sPHENIX

- continuous gap cleaning seems to work for us

- fill number for 56x56 store for original crossing angle studies is 33878

- side peaks with 56x56 orbit, no side peaks with 6x6 store
