Contents
MEDCON 5 restrictions (Bob May email)
- adhere to counting room capacity restrictions
- maintain 6 ft. separation (briefly passing another person inside 6 ft. while moving about the counting room is inevitable and is OK)
- wear masks anytime more than one person present in the counting room
- at MEDCON 5 the lab has no cafeteria services because eating "cafeteria style" (eating in common from prepared food) is inconsistent with COVID-19 controls. Staging food in the counting room to share is inconsistent with MEDCON 5 COVID-19 controls.
- food and drink consumption - because it requires removing face coverings to consume - should be limited to packaged food and drink brought for personal use that is consumed while maintaining at least 6 ft. from the nearest person and ideally, consumed in a separate room from others.

- Next RC meetings at 8:30am?
- Special tasks remaining:
- Periodic harp scans (last one done on Sept. 5th). The rates and transmission have been stable
- Check CCal active basis with 2nA beam. 2h. A. Somov. To be scheduled when Hall C is at 1-pass, Hall A is down and we have our own slit.
- Pair Spec. test. 1h. A. Somov. After the CCal check.
Monday, September 14 at 8:45
- Last 72 hours:
- Production
- On Friday:
- After being down since 2am (vacuum issue), the beam came back at 9am and a empty target run started (target was emptied during the beam down time). Beam down after 30min due to NLvacuum issue and 5th pass separator issue. Beam came back at 15:15. Another empty target run (1h+) was taken and then production resumed.
- During beam down time, Kondo accessed the Hall to install a new power supply for a GEM (PS area).
- Saturday: production
- Beam off from 4pm to 6:30pm due to Klystron change. Sergey accessed the Hall for GEM/TRD work.
- Sunday:
- Owl, 1am: scheduled Raster test (Richard Jones. Mike McCaughan). Beam went down at 1:12am, (Chopper + 2L13 issues) and the test had to be postponed. Beam came back at about 4pm.
- swing: A. Somov worked on SRC trigger fine tuning. Started data taking with SRC trigger at 11pm until rather test at 3:45am next day.
- Monday:
- Owl, 3:45-5:15am: re-scheduled Raster test (Richard Jones. Mike McCaughan). Test was cut short by the PD at 5:15am because it caused too much trip.
- Back to SRC trigger data taking for 30min (accidentally, but the data is welcome. Run 73141) and then standard production.
- Reports/issues:
- RCDB/DAQ test (shorten stop run duration.) Dimitri/Sergey.
- Raster test (Richard, Mike McCaughan)
- Ram disk filling (David Lawrence)
- RootSpy fails on new run (Mark Dalton)
- Run plan
- Continue production runs
- Monday Sept. 14th: beam study.
- 10am - 11am/noon: beam study (access to hall allowed).
- 11am - 16:15: physics beam.
- 16:15 - 21:15: beam study (access to hall allowed).
- Access list:
- 10am: Vladimir Berdnikov (PS area, 1h)
- 10am, tagger vault. Josh F.
- 4:15pm: Lubomir and Kondo (PS area, 1-2h), to install and check a HV module for the GEM setup.
- Friday Sept. 18th, 6am: Hall C pass change from 5 to 1 pass. We should request to run on our own slit.
- Special tasks remaining:
- Periodic harp scans (last one done on Sept. 5th). The rates and transmission have been stable
- Beam rastering test
- Check CCal active basis with 2nA beam. 2h. A. Somov. To be scheduled when Hall C is at 1-pass, Hall A is down and we have our own slit.
Friday, September 11 at 8:45
- Last 24 hours:
- Production, but RF recovery+NL troubles+vacuum issue resulted in only about 6h of useable beam.
- Hall accesses by Lubomir (to reset a crate) and Mark D. (to fix non-working BCal pulser) during scheduled beam down time.
- Hall access by Vladimir Berdnikov (PS area) to reinsert crystals and check communication.
- Reports/issues:
- Run plan
- One last empty target run (2h) (current diamond radiator config., 350 nA)
- Continue production runs
- SRC trigger fine tuning + taking data with SRC trigger. 1 shift (Saturday swing). A. Somov
- Monday Sept. 14th: 10am-16:00: 6h of beam study.
- Tuesday Sept. 15th: due to All Hand Meeting at 9am, RC meeting is cancelled (unless something important happens).
- Thursday or Friday Sept. 17th/18th: Hall C pass change from 5 to 1 pass. We should request to run on our own slit.
- Special tasks remaining:
- Periodic harp scans (last one done on Sept. 5th). The rates and transmission have been stable
- Beam rastering test
- Check CCal active basis with 2nA beam. 2h. A. Somov. To be scheduled when Hall C is at 1-pass, Hall A is down and we have our own slit.
Thursday, September 10 at 8:45
- Last 24 hours:
- Production, with beam available for most of the day. A lot of beam trips however, which will be taken care of by impromptu RF recovery tomorrow.
- Reports/issues:
- BCal hot channel (Fixed by Sergey)
- New PWO crystals installed
- Waiting for CCAL
- Run plan
- Continue production runs
- Large amount of beam trips due to Hall A beam steering problem. Beam will be down at (tentatively) 9am today for an expected 1 or 2h to address the problem.
- Tuesday Sept. 15th: 3h of beam study expected
- Thursday or Friday Sept. 17th/18th: Hall C pass change from 5 to 1 pass
- Special tasks remaining:
- Beam rastering test
- Periodic harp scans (last one done on Sept. 5th). The rates and transmission have been stable
- Empty target run?
