<b> Normal Production running </b>
 
 
*<b>Prerequisites</b>
 
 
<ul> 
 
 
*Make sure [http://opsweb.acc.jlab.org/internal/ops/ops_webpage/restrictions/ops_restrictions.html operational restrictions] are followed.
 
 
*Make sure the raster size is correct (4-4.5)
 
 
*Monitor beam parameters/configuration very often and post an entry like [https://logbooks.jlab.org/entry/3777457 this] at the beginning of your shift and when run conditions have changed
 
 
*Running on cell targets: raster always ON (4-4.5, size will be determined by the scraping checks), orbit locks ON, current ramp rate 1 muA/sec
 
 
*Always take 120Hz of EDTM
 
 
*Fill the BTA with realistic numbers. If the desired beam current is not delivered prorate your ABUs!
 
 
* Change the IHWP every 4 hours when running on glass cells
 
 
</ul>
 
 
*<b>Run plan</b>
 
 
<ul>
 
*Start back with the Beam / Raster checkout (short procedure) [https://hallcweb.jlab.org/wiki/index.php/Beam_and_Raster_Checkout_for_A1n/d2n_(Short_Procedure) Checkout]
 
 
* Production on 3He; if not able to reach requested current, pro-rate the ABUs
 
 
</ul>
 
 
=== Notes for tomorrow's 7:45 meeting ===
 
 
 
==== Future ====
 
 
* Opportunistic target polarization calibration and studies on Tuesday-Wednesday during beam off and Moller measurement (priority is beam)??
 
* We are on the schedule to switch to 1st pass on Monday/Tuesday (17AUG / 18AUG). Need about ~ 3 days at 1st pass and would like to switch back to 5th pass before the weekend.
 
* EPR diode good for now, but check for future planned accesses.
 
* If Hall will have opening for 1+ hours, let Simona know as there is work to do on the cerenkov.
