Commissioning and running of sPHENIX

[Stefan Bathe <stefan.bathe AT baruch.cuny.edu>]

RHIC (see attached link)

- Issue with blue landau rf cavity

  - prevents instabilities during ramp (then off)

  - can’t do 111 without

- need more 56x56 bunch stores to set up machine

10:30am update

RF is in the ring for the blue landau, MCR has the start of store automatic steering working. 

Next ramp we will try another 56 ramp with the landaus on. The stochastic system expert is not available today to set up so we will stick to stores that don't go above 10e9 (about 3 hours). If he is available this weekend at some point MCR will contact him and we can reevaluate store length.

STAR

- no update
