While running CW with C laser through C slit, we deselected the A laser/A-through-C slit configuration to eliminate the need for running with the CW Hall/Slit permissive override on. It's not a requirement but it does create a somewhat safer configuration while A and C share a slit.

Looks like it was real loss, but it's not clear where it was coming from. The more recent one (Fig 1) shows a sort of jagged current loss over ~0.5 ms.

Since we're only using one set of raster coils for the low energy run, we'll need to manually unmask just the "Hall C Fast Raster" bit (Fig 2).

Beam authorization granted for up to 5 uA CW.
Per Ops Restrictions, this target may take up to 100 uA CW with a 2 mm x 2 mm raster on for currents above 5 uA. Raster is OFF.
MaxJuice is set to 7 uA.
BLMs and Ion Chambers are unmasked IAW CW delivery protocols.

One ion chamber calibration for the out-of-beam target position was taken with raster OFF from 1 uA - 5uA (beam auth limited). We are energizing the raster for another calibration from 1-5 uA.

No significant aperture restrictions in the Hall. FOpt showed degeneracy in 4T so there's a bit of a blind spot there.
