Body: 

cavities were pretty far off from the machine frequency
cavity 1 - ~24 kHz
cavity 2 - ~15 kHz

tuned the cavities closer to machine frequency. increased the gradients in SEL to the set points from the last run
cavity 1 - 2.5 MV/m
cavity 2 - 10.09 MV/m

made sure drive level (GASK) and the forward power levels (CRFP) are similar to the ones from the last run

poff optimization was done after tuning the cavities. used the one button to recover the cavities into SELAP

Update to the No-Touch List: Cryo was experiencing issues with the heaters in 0L02, 1L08, 1L09, 1L12, and 1L21. They said operation of 0L02 is fine since the heat load is so low, but do not turn RF On in 1L08, 1L09, 1L12, and 1L21.

Additionally, when attempted to turn on HV in a zone, if it is not successful after two attempts, file an Ops-PR and move on to the next.

HCO was done on the Trim Racks in W1 service building, and all of the East Arc and Tagger service building; all magnets where set to +/- low current for 30 min and then cycled. All magnets and Trim Rack are ready for operation.

W202B17 and E301B11 has been added to our list of Trim Racks with W301B13, that we will need to investigate some issues with.

All 20 Amp Power Supplies in the East and West Arc as well as the Tagger service building, has been Powered On and place in Standby / Remote mode.

Controller chassis seems to be operating as expected. Inspected interface chassis again to find that one of the resistors apart of the voltage monitor circuit to be unsoldered. Fixed that and letting it run on control power to see if the issue is resolved.
