Body: Fopt 7.9 completed successfully. The runtime settings include a sample count of 15, a minimum current of 4, and an operating regime of Standard with Excitation in 1S Region. The corrector and RF kicks applied were 0.488208 and 0.488208 volts respectively. The max. amplitude setting was 1 millimeters. The files for this run were saved in the directory /cs/opshome/hlapps/optics/diforb/26apr101255. The X and Y stability of the machine during the run was 0.132982 and 0.168346 (mm) respectively.

Degaussed MDL0L02 and resteered inj to inline dump, only a tiny adjustment to 0L02BH was required.

DC Power is pulling the trim card.

Had to resteer to the ILD again... just moved the 0L02BH corrector back to where it was at.

Corrected GP and let locks run to xC dumplette after pulling the ILD.

Set Free Run Frequency to 59.0 Hz and started taking data at 11:36:11.

Set free run frequency to 59.9 Hz at 11:41:32. I will collect BPM data and run Jerone's SVD analysis.

Fig 1: Oscillations still here with the trim card pulled.

I've set SCAM back to line sync.

Placing this task on hold for now due to the require for PSS re-certification (thank you for catching my oversight). We would only execute this task unless we know for certain that this magnet is causing the oscillations. After speaking with Crew chief, preliminary studies suggest that the oscillations begin upstream of this.

changing the scam line sinc from 60 to 59.9 and verified that our signal is at near exact 60 Hz. And it is coming from the early 0L region as per the BPM SVD. Given this, we plotted individual BPMs and found that the signal originates between IPM0L02 and IPM0L03. Between these are IBC0L02, the MDL0L02 dipole, A few correctors, the degrader solenoid, and some quads.

A quick test of turning off the heater jacket verified that its not the cause of the 60 Hz oscillation. Moving on to the dipole

PTW is approved and will be placed On Issue following completion of a Pr-job brief.

Swapping of this power supply will require PSS certification. We are waiting to see if this work will happen today or Monday.
