As it stands now, 1L23 won't stay in HV long enough to do any measurements.

Started swing shift by attempting to improve optics with low energy to the ILD. IHA0L03 was well matched between the Wien configuration for high and low energy setups, and viewer walks were fairly close up to the mid-0L, so we decided to attempt to match with IHA0L08. The first IHA0L08 scan was abysmal, with an X sigma of ~1.8 mm, and the X-plane emittance measurement showed a beta of ~2.5 km which made for a /very/ aggressive match, so a little bit of pre-match tweaking was in order.

Attempting to take y-plane match data and the harp zigs but doesn't zag. One can see from the most recent scan in figure 7 that the "potScaled" axis is miniscule. When the harp is zeroed after the scan the potentiometer readback returns to the expected value but the servo motor position readback reaches something like -300 or -400 mm before getting set to zero, presumably when the harp hits a limit switch. Compare the behavior of IHA0L03 (Fig. 8) to IHA0L08 (Fig. 9).

Seems that it turned itself off for some reason. Guess that's a wrap for tonight as far as the A laser is concerned.

Could only keep cavity on at around 14MV/m. Above that it was tripping off. Tuning was much more stable than cavity one however.
