Hall C requested NMR Measurement. I chose to document what the rates are with no C beam (Fig. 1)

HA is at 150 uA.
Feed Forward is still non-functional.
The Hall requested that FFB be turned totally off (i.e. Sys OFF, RF OFF, BPMs in Normal Mode).
'SEE Norm Ops' is visible indicating BPMs are in normal mode.

There is Hall A FFB system and Hall A Energy Modulation System both of which have a RF part that feeds SL20 Vernier inputs to all 8 cavities. Hall A FFB system always, always, always has priority over Hall A Energy Modulation System Electrically. Hall A Energy Modulation Systems RF Vernier will have no effect if Hall A FFB System is on. If you want Hall A Energy Modulation Systems RF vernier output to have a effect on SL20 RF cavities 1 thru 8, Hall A FFB System has to be off (That is the way the systems are designed).

HA is receiving 20 uA CW on Ca-48.
Will eventually ramp them up to 150 uA
Ion chambers were set from the values given to us by the hall (for 150 uA).
Trying to re-confabulate HA FFB.

The hall is investigating the response on one of their magnet coil (C07). They requested FFB OFF (i.e. Sys OFF and RF OFF).
