First, I rocked chopper 1 gangphase back and forth to see whether all three beams are extinguished on the 0I05 viewer at the same time, indicating that the barycenter of the beam spots is centered on the master slit reference hole and the phase of all three beams is properly centered on the apertures of the master slit.

While iterating between adjustments on the 0I05 and 0I06 viewers, turning off the MFX0I06 solenoid eliminates confusing coupling.

I find it useful to leave the beams separated in the horizontal plane while establishing colinearity in the vertical plane as one can more easily

Figure s 1 and 2 show the V-Wien temperature PVs in Celsius along with the V-Wien voltage and magnet PVs.

The chiller temperature set point was changed from 22 to 18 C on 01-21-2026 at 13:00.

There seems to be very little change in temeprature vs. magnet current with the new chiller temperature set point.

When the V-Wien spin rotation angle is changed from +90 to -90 deg, this executes the following commands:
1. Set the output voltages to zero in each HVPS
2. Set the magnet current from +16 to - 16 A, executing the hysteresis loop
3. HV switcher chassi polarity flip
4. Ramp each PS from 0 to 18 kV

Step 1 is executed without slow ramp. This seems to trigger pressure spikes in the injector beamline. See figure 1, and figure 2 for a zoom in time.

I suggest to implement a slow ramp down / ramp up (similar to that fot the gun HVPS) to each of the Wien HVPS.

Claire has updated the Wien thermcouple Labjack PVs with the room temperature readout correction factor. Now each of the 2 Thermocuples PVs in each Wien filter are reporting expected temperature values.

Next step is to add these PVs to their corresponding Wien controls screen. I will coordinate this with Claire.

The procedure works well to get everything lined up on the 0I05 viewer. I was topping out on the available 2Y gradient, so the 0I05 beam spots aren't directly on top of one another, but I'll fix that in the next stage where I'm getting collinearity roughed in on viewers. Seems like I'm chopping too hard with 1Y.

It may be useful to rearrange some steps to get the beams visible (not on top of one another) on 0I05 and only THEN insert the master slit to check that you aren't losing beam on it.
