Current Status
- Jun 16 - Swing (yesterday)
- Received up to 25 uA of beam and did Carbon Hole check Carbon Hole (Raster ON), Carbon Hole (Raster OFF)
- started HMS optics studies
- Jun 17 - Owl (today)
- limited to 15 uA beam due to accelerator issues (Ops will work on Hall C line today to try and give us higher currents)
- completed the detector checkout part of run plan
- while doing +/-8 cm C12 optics run plan, HMS Dipole interlocked (~ 4:30 am )
- SHMS optics was taken instead in the meantime
- towards the end of Owl, HMS Q2, Q2 Dipole had all went to interlock
- Jun 17 - Day (today)
- S. Lassiter arrived and it currently in the Hall with Hall C techs working

Current Run Plan
- Complete Carbon Foil +/- 8 cm (part of HMS Optics plan) ( DONE )
- Complete Single Carbon Foil on HMS
- Do Coincidence Trigger Checkout
- Do single Heep coin setting
- Begin production physics
Notices in Effect for Shift Crew
- Please pro-rate ABU for max current limit in run plan (uA) in beam time accounting. For example, if we receive 15 uA instead of the max_current_limit in the run plan, then the ABU should be: ABU_prorated = 15/(max current limit) * ABU

Current Issues
Planned Accesses to the Hall
- During the next accelerator maintenance period (Wed Jun 22):
- S. Lassiter needs to put crush washers in LCW filters, so we may see a little bit of water by the HMS boogie for now, until he can put the washers next week, during maintenance period HMS Dipole LCW ( PENDING )
- Need to check SHMS ROC 4 Slot 9 Channel 0 FADC for potentially loose connection, as Column 5, Row 1 block appears to have no occupancy. SHMS Cal Occupancy ( PENDING )
- Xinzhan Bai request to go to restricted access to quickly swap MPD electronics out and check signals (~ 30 min.), whenever there is extended down (most likely during next accelerator maintenance period) : Contact: xbai@jlab.org, cell: (434) 422-2809 ( PENDING )
Planned Accelerator Configuration Changes
Special Requests
- Mark Jones would like to take HMS optics data with a 4x4 mm^2 raster at some point (when HMS is at a lower momentum, i.e., current setting) for checks. ( PENDING )
