Hall A -> 5 uA on Carbon Optics

Log Number: 4065660Logbook(s): Entry Makers: bschaumlBody: 

Hall is authorized up to 60 uA CW.
Per Operational Restrictions, with the Carbon Optics Target, the hall may receive up to 60 uA CW with raster A on at V=1.3409 & H=1.2068.
Max Juice is set to 7 uA
Raster A is on at V=1.3409 & H=1.2068.
Cooling Jets are OK.
Ramp Protection is ON
Ion Chambers are set using the "Carbon Optics" calibration for 5uA with a 30% margin.

1L10-6 POff Optimization

Has been particularly trippy as we send 60uA to Hall C. Hoping this calms it down some. Otherwise, may end up de-rating.

guidance for adjusting Hall A beam envelope

Log Number: 4065620Logbook(s): Entry Makers: roblinBody: 

The Hall A optics are such that the last six quads are off . As a consequence C19 and C20 quads can be used to adjust the beam envelope.
As a general rule, you should find that for both X and Y, size at H04B > size at H04A, that is the beam is diverging (on purpose).
If the Hall A staff tells you that beam is :

too big in X:
reduce the amplitude of MQR1C20 (less positive)
too big in Y:
reduce the amplitude of MQR1C19 (make it less negative)

if its too small do the opposite.

Alternatively , you can also use matching quads ike 1C08.
