Daily RC/OA Meetings at 13:00 in CH Room 200C, and on ZOOM: URL Link (Meeting ID: 1611984219; Passcode: RGD-RC23), except on Wednesdays, which is on ZOOM ONLY @ 15:30 due to the conflict with the 13:30 MCC Scheduling/Planning meeting.

Important Notes

Do NOT change FSD settings without approval from RC or beamline expert!

• In case of medical or fire emergency, call 9-911 from a LANDLINE phone in the Counting House and inform the Crew Chief and RC.
• In case of evacuation of the Counting Room (e.g., due to a fire alarm), grab the shift expert phone and leave the room through the "EXIT" door leading to the parking lot. Do not leave through the hallway! Call the RC once outside so the latter will call MCC to turn the beam OFF to Hall B and inform other Hall B staff members.
• If you have symptoms or a positive COVID test, do NOT come to your shift - instead, inform the PDL and the RC and JLab medical services immediately to arrange replacements.
• Remote shift: If needed, worker shifts can be taken from off-site. Inform the PDL and RC. Also, make sure that you follow the instructions under the "Shift Worker" tab, as you need some lead time to set up!

• Note to Shift Takers:

◊ Read the ESAD, COO, RSAD, and ERG documents found on the "Current RG-D Run Info" as well as the yellow folder in the counting room. Before you start your first shift on the current experiment, you must sign on the list in the yellow folder. Thereby, you confirm that you have read and understand their content.

◊ Read at least the previous 24 hours logbook entries to be aware of recent run details and changes;

◊ Arrive at least 10 minutes early for shift change;

◊ Refresh the runwiki page/tabs; look over it/them every shift:

- Follow the Shift Expert/Worker tab's instructions.

◊ Do not spend more than 15-20 min trying to fix a problem. In case of any issue, contact the On-call Experts or the RC.

◊ Review these important links:

- Recent Changes and Current Issues

- General How-to for beam restoration procedures and Møller runs.

Run Plan, Thursday, Dec. 14th - Friday, Dec. 15th, 2023 Continue CuSn data-taking as follows until 7 AM on Dec. 15th when the beam will be taken away for the RG-K setup: - Target: CuSn - Beam Blocker: IN - Beam current: 100 nA +/- 4 nA on 2C21A - Run duration: 100 M events - DAQ configuration: PROD67 - Trigger file: rgd_out_v2.3_Q2_1.2.trg P.S.: If the beam is widely fluctuating above 105 nA, constantly overshooting over 105 nA on 2C21A, please ask MCC to narrow down the fluctuation margin to keep it below 105 nA based on 2C21A reading. They could put the beam current monitor lock on 2C21A in case that may help with the wide fluctuation and/or adjust our laser phase as well as narrow down the slit width, see ELOG entries 4224300 and 4225220.

General Instructions The main lights in the Hall (dome lights) and the Forward Carriage lights are being kept off because of light leaks affecting some of the detectors (especially ECAL sec 2 and 3). If these lights are switched on during an access, they should be switched off when leaving the Hall. • Refer to these photos: ON: [1], OFF: [2] • We have a new dome light switch outside of the hall in the labyrinth. The lights can be turned off without entering the Hall. See logbook entry: https://logbooks.jlab.org/entry/4204460 • Note that when the dome lights are switched off, they cannot be turned back on immediately because they require 10-15 min to cool down. Beamline: • Ignore the Faraday Cup beam current (see Current Issues). • Do not run over 30 minutes above 90 nA with a 5-pass beam without the beam blocker IN . The beam blocker must be IN for long-running at high currents for 5-pass operations. • If there is any concern about beam stability, ask MCC if orbit locks are on (they should be). • Document any beam condition change and send scaler GUIs to HBLOG. • If HWP is changed, start a new run: ◊ Please check with the beamline expert whether the SLM and FCup charge asymmetry (Q-Asym (%)) readings are set properly, as they will be out of range in case Eugene's script is not run by the experts after the HWP change. The absolute values should be less than 0.1%. For beam tuning and Møller runs • Make sure the SVT/MVT are set as follows: SVT: LV ON; HV OFF, and MVT: LV ON; HV ON in SAFE Mode. - When turning MVT OFF, do not press "BMT HV OFF" from HV->Overview->Actions, but instead select BMT HV ON - Safe Voltage. The same applies to FMT select FMT HV ON - Safe Voltage. - When turning MVT ON: go to HV->Overview->Actions, and select BMT (/FMT) "HV ON - Full Voltage". - DO NOT start runs in SAFE Mode for Production/Calibration/Various-Studies. • Turn DC HV off only for beam tuning; if no beam is available or when the beam is stable, keep them on even if you are not taking data. To access the Hall: • If you need to enter Hall B, alert Denny Insley (757-897-9060, cell/text: 757-810-9576) and the Run Coordinator (757-575-7540). • Check in with the shift personnel before entering the hall.

DAQ Operation & related General Instructions

(New) STANDARD end and start of the run: - "End run" - "Abort" - "Download" - "Prestart" - "Go" If any ROC crashes, find out which one (look at the ROC Busies GUI or ROCS tabs in the DAQ runcontrol), and end the ongoing run, which might fail to end properly, and that is OK. You SHOULD do "Cancel" and "Reset" in the DAQ Run Control before issuing a roc_reboot command ON JUST THAT ROC and continuing with the DAQ Restart chain from "Configure". Test with ping ONLY instead of ssh to check whether the ROC is backed up. ◊ When pinging a ROC, e.g., "ping mvt1", stop it with Ctrl+C after a couple of printouts showing different latency times. Restart DAQ from Scratch when changing configuration or trigger files, or when the run did not end correctly, or when ROC(s) is(are) rebooted, or when RICH is Fastly/Fully recovered, as follows: - "Cancel", "Reset" - "Needed operations: change configuration or trigger files, or a run did not end correctly, or a ROC crash or RICH is Fastly/Fully recovered"; - "Configure" - "Download" - "Prestart" - "Go"

Configuration is PROD66/67 (or PROD66_PIN for fast reconstruction of some calibration/reference runs from the cache disk). • As of 11/25/23, whenever there is an issue with the RICH alarms that can't be resolved within 10 to 15 minutes, please contact the RC (/AC) and the RICH experts to discuss the issue. Meanwhile, we may switch the DAQ configuration to PROD67_noRICH until further notice; see the logbook entry #: 4226898. In case of DAQ Disk space alarm, call the DAQ expert. Trigger files: - Inbending production: rgd_inb_v1.0.trg - Outbending production: rgd_out_v2.1_Q2_1.2.trg or rgd_out_v2.3_Q2_1.2.trg with low-Q2 suppression During "Configure", observe the ROC terminals to see whether any ROC has error messages. Some ROCs keep printing error messages while functioning properly; please see their list in this logbook entry # 4215299 to avoid unnecessary reboot since the printout in the ROC terminal won't change. If they get disconnected, the message will appear in the run control itself! In case of DAQ livetime "0" alarm, RESTART DAQ from Scratch; • Note that you also get a DAQ livetime alarm at the start of a run; that is OK and can be simply acknowledged. Unless a RICH problem crashes the DAQ, do NOT interrupt an otherwise smooth run for a RICH recovery. Instead, do this in between runs. The shifter MUST check and reset monitoring histograms at least once every 30-60 minutes to ensure no significant detector problems. Sometimes, this is the only way to know that a specific ROC needs to be rebooted. Pop-up window: Enter the beam current and the type of run (e.g., Production and HWP state, IN or OUT) in the "Comment" field. After each step of a DAQ RESTART, ensure it is completed in the Run Control message window. Also, during "Configure", look for error messages in the ROC terminals. • Contact the DAQ expert if you have any questions or doubts about how to proceed. At the start and end of every run, check that the data filled in the Run Condition Data Base (RCDB) is correct, especially the manually filled fields.

Responsibilities

Getting Started Standards

• Ensure the safe and efficient operation of the experiment; see the detailed duties in the COO.
• Check the shift schedule and training status of your shift crew (before YOU start!).
  • Training Status: Skill Requirements List; Fill in the user's name and search.
    • Training requirements for shift should also be in the COO, and they are:
      • ES&H Orientation (SAF 100);
      • Radiation Worker Training (SAF 801);
      • Oxygen Deficiency Hazard Training (SAF 103);
      • Hall B Safety Awareness Walk-Through (SAF111)

Daily

• Attend the daily MCC meetings (7:45 AM and 8 AM Daily) in-person when running except on the weekend, which are virtual on ZOOM but @ 9 AM.
  • See the ZOOM connection info under Important Links tab.

• Update the daily run plan in the Short Term Schedule tab in coordination with the AC and the run group, and clearly communicate it to the shift crew.

• Run the daily meetings at 1 PM in CH Room 200C and on ZOOM, except on Wednesdays, which is in ZOOM ONLY @ 15:30 due to the conflict with the 13:30 MCC meeting and the unavailability of the CH room afterward;
  • To connect to Zoom in CH Room 200C, follow these steps:
    • Turn on the projector with the white remote control, then log into your CUE account. If not listed yet, click on "Not listed?" in the bottom left to add your account.
    • Once logged in, use the recommended Google Chrome to join the ZOOM meeting on the browser without downloading the application.
    • Since the room doesn't have audio, don't connect with the computer audio, but choose "Call Me", then enter the number written in the small Cisco device near the microphone in the middle of the conference table. Once it rings, answer the call, and you will be prompted that you have joined the meeting.
    • The room has a camera, so you may turn it on if you wish in the ZOOM browser interface.

• Check on shift crews at the start of each shift, especially if they are new!

• Send daily RC summary to the HBLOG, hallb, clas_members, and rgd_ana mailing list with the essentials.
  

Weekly

• Attend in-person the weekly MCC scheduling meeting on Wednesdays at 1:30 PM and report the run status via the submitted Run Coordinator Weekly Summary;
  • The report summarizes the data-taking status with regard to the available beam used, any beam losses, unavailability of the beam, etc., from 7 AM past Wed. through 7 AM the Wednesday the report is due, in addition to any standing and/or critical issues, plans for next week, and general comments/requests, if any.
  • Refer to the RC Timesheet to calculate the percentage of scheduled experiment hours to date.
  • The total experiment data collected to date could be retrieved from the up-to-date "Accumulated Charge" depicted on the "Total Charge on Target Plot" in the Monitoring tab (TBA as the run starts).
  • A detailed plan of the target configuration change will be generated as soon as the run starts; however, an overview of it is summarized in slide 6 of this RG-D Overview.

• Attend the weekly Hall B meeting on Mondays at 9 AM and present your summary slides that should be sent beforehand to the Hall B leader, Patrick Achenbach, after checking them; please, with the Analysis Coordinator Lamiaa El Fassi.

Tasks

• Come to your shift in time for the shift change, 10-15 minutes before the start of your shift.
• Follow the Short Term Schedule as outlined by RC
  • Run Plan, DAQ Configuration, and References and Standards
• Keep shift summary up to date in HBLOG. Record all that happens.
• Do a RICH recovery (press the RICH Recovery button on the GUI) once daily during the day shift, between runs. Please log in shift summary.
  • Note the automated "RICH Recovery" sequence already confirms RICH4 is up and accepting SSH connections before claiming success.
  • You have to "Cancel->Reset->Configure->Download->Prestart" before starting the next run.

• Fill out BTA hourly. Click "Load from EPICS" to fill the left side automatically, then correct as needed.
  • Accelerator beam time:
    • ABU: acceptable beam used (e.g. harp scans, calibrations, trigger settings, running)
      • 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.
    • BANU: beam acceptable but not used (e.g. target change or our problems)
    • BNA: beam not acceptable (e.g. tuning, drifting, not focused)
  • Experiment beam time
    • ER: experiment ready
    • PCC: planned configuration change (when the beam is masked while radiators are moved, DAQ (stopping/starting runs, tests, ...) are PCC.
    • UED: unplanned experiment down, is used for hardware failure
  • Enter fields at the tab "Shift Information"
  • Promptly send "Info for MCC" at 7:00, 15:00, and 23:00
  • Sign, viz log completed 8-hour sheet
• If the worker shift is remote, maintain communications with them in Zoom: https://jlab-org.zoomgov.com/j/1619881100

In case of other questions or uncertainties of what to do, call the RC or PDL
