<p>NOTE: I am sending this email to a broader range of mailing lists because<br />
I've heard that some are not receiving these updates. Operational<br />
updates are being sent to a new 'Halla_running' mailing list:<br /><a href="https://mailman.jlab.org/mailman/listinfo/Halla_running">https://mailman.jlab.org/mailman/listinfo/Halla_running</a></p>
<p>*** If you are part of the DVCS and/or GMp collaboration, are going to be<br />
*** running shifts, or want to receive these posts, use the link above to<br />
*** subscribe.</p>
<p>Dave Gaskell <<a href="mailto:gaskelld@jlab.org">gaskelld@jlab.org</a>> is the new Run Coordinator. The Hall A<br />
RC phone is MIA right now, so email or use the jlab webpage to reach him<br />
in the near term.</p>
<p>-----------------------<br />
RC update for Wednesday<br />
-----------------------</p>
<p>No major status changes last day. Hall D has 2 shifts under its belt now, but<br />
accelerator problems persist so it is slow going on their commissioning<br />
checklist.</p>
<p>There is still an outside chance that beam will be available in Hall A during<br />
SWING on Friday.<br />
- General shifts are cancelled through Friday OWL.<br />
*** The TO for Friday OWL is still on the hook though (assuming the target<br />
cools successfully on Thursday). Contact the RC for<br />
details/confirmation.<br />
- The Friday DAY shift leader should be on standby (contact the RC).<br />
- Regular shifts could start Friday SWING</p>
<p>The target cooldown will proceed as planned during Thursday DAY shift. If it<br />
goes smoothly then they will use it for practical training during SWING and<br />
likely leave it cold overnight. The expectation is to warm it up on Friday<br />
DAY, but that needs to be confirmed.</p>
<p>A classroom target training session is still planned for 1:30-3:30 on 11/6<br />
(Thursday) in CEBEAF Center room B101. Contact JP Chen <<a href="mailto:jpchen@jlab.org">jpchen@jlab.org</a>> if<br />
you are a TO to get trained. Note that you will probably need the practical<br />
as well -- talk to JP or Greg Smith for details.</p>
<p>-----------------<br />
Plans (Tentative)<br />
-----------------<br />
- Wednesday (ongoing)<br />
- DAQ stress test<br />
- ROC sync monitoring needed<br />
- use EDTM(?) to trigger both LHRS and Calorim at high rates<br />
- verify no bottlenecks in system: ROCS-->DAQ--->Tape<br />
- test buffering mode</p>
<p>- Thursday:<br />
- target cool down (DAY shift)<br />
- target training (afternoon)<br />
- will attempt to lock-up the Hall mid-afternoon for ~2 hours to allow<br />
MCC hot checkout of box supplies</p>
<p>- Friday:<br />
- will likely warm up cryo target during DAY shift<br />
- RF separation work during DAY and SWING shift, possible beam in<br />
late-SWING?</p>
<p>----------------------<br />
Pre Hall lock up items<br />
----------------------<br />
- RadCon checklist<br />
- Hall Checklist (Work Coord: Jesse Butler)<br />
- MCC Hot checkout<br />
- attempt on Thursday (needs ~2 hours)<br />
- get the upstream harp hardware moved to the target girder harp<br />
- move the DVCS calorimeter away from beamline before beam?</p>
<p>----------------------<br />
Hall Punch list Items:<br />
----------------------<br />
- verify operational restrictions<br /><a href="http://opsweb.acc.jlab.org/internal/ops/ops_webpage/restrictions/ops_restrictions.html">http://opsweb.acc.jlab.org/internal/ops/ops_webpage/restrictions/ops_res...</a><br />
* looks OK, might be worth cross checking with Dave Meekins</p>
<p>- Hall A cell phone (Thia, Doug)<br />
- in progress</p>
<p>* Need "Bullet point" run plan for RC and shift crew (Julie, Carlos, Alex, Charles)<br />
- Some items are here:<br />
DVCS: <a href="https://hallaweb.jlab.org/wiki/index.php/Run_Plan_(DVCS3)">https://hallaweb.jlab.org/wiki/index.php/Run_Plan_%28DVCS3%29</a><br />
GMp: <a href="https://hallaweb.jlab.org/wiki/index.php/Commissioning_Run_Plan">https://hallaweb.jlab.org/wiki/index.php/Commissioning_Run_Plan</a></p>
<p>- Need online shift checklist for shift crew</p>
<p>- SuperHarps (Sue Whitherspoon, Omar Garza, Ernest Stallworth)<br />
- 5/6 working, we're missing hardware for the 6th<br />
- missing harp is just upstream of target (confirmed)<br />
* need to arrange to have the upstream hardware moved to the target girder before beam</p>
<p>- BCM status (Luke)<br />
- 'legacy' 1MHz BCMs have been verified in the LHRS scalers<br />
- new 'Qweak' style receivers are installed but not working yet (Musson's<br />
group needs to install firmware). Once ready they'll need some test time.</p>
<p>- Unser status (Dave Mack?)<br />
- still some work to do<br />
- pedestals drift a bit</p>
<p>- Moller status (Roman is onsite)<br />
- Moller checkout could be an option if we are restricted to very low<br />
currents (ie. excessive trip rates at higher currents, etc)</p>
<p>- ARC energy equipment status? (Doug, Rick Gonzales)<br />
- unclear, "should work", but there are a lot of unknowns</p>
<p>- F1 TDC readout and decoding (Steve, Alex, Marco)<br />
- F1 decoding is being added to analzyer now (Marco, Steve)</p>
<p>- Crate sync scalers and/or ADCs (Paul)<br />
- in progress as of Wed</p>
<p>- Cosmics checkout questions (Kijun, ???)<br />
- GMP trigger mode vs. DVCS trigger mode (not sure of the difference)</p>
<p>- Helicity signals (Buddhini, Alex)<br />
- signals plugged in, but not clear what the associated FB ADC channels are?</p>
<p>- Logbook fixes (Brad)<br />
- I added some 'pre-filtered' lists under 'Useful Links'<br />
- ie. run-starts, run-ends<br />
- let me know if there are others you want<br />
- added 'Autolog' tag list on (new) automatic entries so the 'Exclude<br />
Autolog' option under 'Display Settings' will work to suppress<br />
start/end-of-run entries</p>
<p>- New TCL/tk 'halog' utility (new logbook only) (Brad)</p>
<p>- Firefox seems to be broken on adaq cluster (Brad)<br />
- <a href="mailto:a-onl@aonlX">a-onl@aonlX</a> accounts are fixed<br />
- adaq@* on the todo list (Brad)</p>
<p>- HRS angle snapshots into DAQ (Brad)</p>
