** IF there is any ammonia sample (NH3 and ND3) in the target, the raster '''MUST''' be operating at all times. The Raster FSD must be UNMASKED. Orbit locks MUST be OFF (except for brief moments to restore beam position).

* '''After each change of running conditions''' (target type, luminosity): Please check that the trigger alarms (on rate/nA) are set appropriately and change them as needed.
 
 
* Whenever you change the raster offset, ask MCC to NOT correct whatever happens on 2H01. Note new 2H01 values and inform MCC of the new 2H01 x and y values - then they can keep the beam at those positions.

* NOTE: It should no longer be necessary to quit RasterMon at the end of each run and restart after a successful "Go" for the next run, but if DAQ crashes, you SHOULD follow these steps, and the same for mon12. '''Make sure there is ONLY ONE INSTANCE of RasterMon AND mon12 running anywhere in the Counting House.'''

* REMINDER FOR ALL EXPERTS: Please take care to fill out the BTA carefully and correctly. The info from EPICS is not always correct, e.g. when taking data with low beam current, you should change the ABU to the proper (estimated) time by hand instead of simply accepting "0" if you are actually taking data. ALSO: Make sure that the target type is reflected accurately on the target and beamline GUIs.
