Flipping one counterwound solenoid at a time to see if one of them is responsible for the spin precession around the longitudinal axis that seems to originate between HWien and Mott.
Ali is logging the Mott results separately.
VWien=-90, flipper +/-, HWien=0.

MFX0I01: originally at -220 (#10105 IN, #10106 OUT); trying +220 (#10107 IN, #10108 OUT) and then another run at -220 as a sanity check (#10109 IN, #10110 OUT)

MFA0I03: difficult to flip sign without messing up the orbit in the chopper.
Changed plans to turning the chopper off and comparing.

Starting from Ops setup, but with HWien=0, VWien=90 (nominal), flipper +/-.

Opened Mott valve (unmasked).
Unmasked FSD bit for IBC0L02 to trip above 5 uA CW (calibrated by reading counts in expert screen; trip limit at 3500 counts).
Set up beam to Mott target, p=5.5 MeV/c, booster crested.
Allsave #26568.

Ali is running CODA from my account on another machine to learn the steps.

Every source of information I can find indicates that we can turn this zone on (SRM, ATLis 118909, RF HCO Spreadsheet, and so on), AND we have turned this zone on an ramped it up in this start up period already (see attached ELog). It was off when I came in this morning so, with all those checks bolstering my confidence I attempted to turn it back on. However, it tripped out of HV almost immediately afterwards.

It looks like earlier this week cav 3 was unbypassed due to its Sorenson being replaced. I'm wondering if this has anything to do with it tripping out of HV.

We will not be sending beam down either of these lines for today's beam studies. Additionally, VBV0L01B is on another unmasked channel so we will still be alerted if this valve closes.

Making this log because, while we have standing orders indicating that masking VBV3D00 is okay, I couldn't find any documentation on VBV5D00. According to the Injector Quick reference doc, VBV5D00 is disconnected at this time. As such, it may make sense to add VBV5D00 to ABIL.
