Steering/ Reducing loss

14 hours 58 minutes ago
Log Number: 4538225Logbook(s): Entry Makers: janakBody: 

Steered around the entire machine after loading Allsave. Regions with most loss are 3R10 and 7S01. Steering was hindered by the fact Even Arc orbit locks are not compatible with tune mode as of this morning.

Made corrections in nearly every recombiner region, making sure launch into each Linac was as good as possible. The strongest focus was in the odd recombiner regions to limit noise on 3R10.

After recovering CW to hall C, we were experiencing more trips fro 7S01, this was caused by bleed through using C beam, which was not making it through AR10 region.
