Data Management plan

Data Management Plan

1. The data generated in the course of the proposal are created at the Scientific Data & Computing Centre (SDCC), formally known as the RHIC and ATLAS Computing Facility (RACF) at Brookhaven National Laboratory (BNL), and under the supervision of the STAR Collaboration.  These data are shared with the entire STAR Collaboration and Brookhaven National Laboratory.  STAR maintains a complete backup archive of all data generated at the SDCC. These data are available from STAR to the public according to the data management plan of STAR and BNL.

2. All the results of analysis carried out here at XXX are made available on public websites that are maintained and backed up by STAR.  These data files are machine-readable and provide all the data and figures of all published work.  In addition, an analysis note is prepared for each publication that includes a complete description of all the steps used to analyze the data and a complete list of the computer codes including macros to produce the published figures.  The computer codes and figure macros are verified by other STAR collaborators prior to submission for publication.

3. The XXX group follows all requirements given by BNL, STAR, and the SDCC concerning data management.

4. The XXX group maintains its training in Cyber security both at BNL and here at the [Your institutions].

BBC/ZDC/VPD HV system (LeCroy1440) communication problem

Loss of communication with LeCroy1445A.

It often happens when LeCroy was turned off, or loses its power due to power dip.
Indications are:
- "bbchv" app on sc3 shows black on/off
- "bbchv" app doesn't update readout voltages/current
- Cannot turn on/off from "bbchv"
Solution is:
Go to SC5 computer. There should be "Restore LeCroy Communication" window:
   
LeCroyRestart

Follow the instructions on the window.
If the window is not on SC5 - open a terminal and type ./scripts/restartLC.py
Make sure you have bermuda terminal open in the next monitor 
(If not, open terminal, type "sys@bermuda" command. Password is the same as one in shift leader's binder for SC5 sysuser)

Controlled/Restricted Access Requests

• The period coordinator/shift leaders should have a list with controlled access requests.
• Leave your phone number if you want to be called for unscheduled controlled access.
• There are only 8 keys for controlled access.
• Always let the shift leader know when you go in and come out.
• Make a note in the elog about the work that was performed.

• Next maintenance day on Thursday, March 9, 2017 (7:30am-3:30pm).

Notes from Operations Meeting

Friday, July 5, 2024

Status & Issues

• At the start of fill 34747, problems starting with TPX[30] and failing STP resets. Run couldn’t be stopped properly and VME #62 power cycling wasn’t successful. Akio looked remotely, but also couldn’t help. Jeff eventually separated problems with trigger from TPX. pedAsPhys was successful on second try. Then hard reset of TPX[30] in the DAQ room. (Error in dsm2-3 in STP monitoring is not critical for data taking.)

This happened again when fill 34748 was lost. Shift crew tried to power-cycle VME #62; no success from control room or Jeff remotely. David got a short access, couldn’t power-cycle on the crate itself. Tim was not available, so we decided to hard reset (unplug). Fortunately, this solved the problem and VME #62 came back just as RHIC was about to reinject.

•  TPX, iTPC & FST deadtime issues in a few runs throughout the day. Clarified how to mark the runs and recovery with shift crew. (many auto-recoveries in early runs in new fill)

• sTGC pressure PT-1 yellow warning (fluctuating around threshold, may reappear during the daytime)

• FCS DEP 04:5 failed once (DAQ message has instructions for shift crew, no further issue)

• David changed the sTGC gas bottle

• Manual power-cycling of TPX RDOs 11:6 (many times), 22:6, 03:4, 14:6

Schedule & Plans

• Machine development today (~5 hours)

• Test run for trigger modifications; details will follow (Carl, Jeff)

• Continue physics: pp200_production_radial through the weekend

• Suggested to try to reproduce the VME #62 problems during next maintenance day for better diagnosis

    Chris worked on it, needs elog entries. 
    QT rate seems to be up (4KHz, 40% dead) => 5KHz normal deadtime 
• VPD: tac zero out. Be ready today for data-taking 
• Gene analyzed data from Monday/Tuesday for studying the background effect. 
  see effects and need to keep BBC blue+1.7Yellow background <200KHz 
• sTGC: time bin cut? Access to gain change? 
• Readiness checklist update for physics available. Shift crew started to follow normal operation procedure. Prom_Check DAQ+TRG+iTPC once a day (no event, stop run after it starts).

§  RHIC Schedule

4K cool down.

Plan for this week,

·      111x111 bunch collisions for experimental setup overnight.

·      Machine development today (10:00 – 14:00).

·      Crossing angle 1mrad at STAR; leveling at STAR made signal/background ratio very small. Reverted back to without leveling.

                          

§  STAR status

·      Physics running started around 4am this morning. We created a temporary configuration and promoted MB-BBC, MB-TOFmult4, BBC, ZDC, EPD.

·      Global timing moved back 2ns. CAL SCAN was redone.

·      EPD trigger timing - one clock late issue resolved. Eleanor fixed it! A few minor changes should be done. All detectors calibration done. VPD E and W max tac value changed from 1950 to 2100.

·      ZDCSMD issue, Aihong took some pedestal runs and coordinated with Hank. The channel 4 has a high pedestal. Issue is associated with the QT broad. Will discuss in the trigger meeting.

·      Previous Issues:

o   L0L1 turn-off issue (Tim changed fan tray for L0L1 crate 62)

o   low rate with QT crate in issue (investigation ongoing).

·      Gene showed the space charge calibration plot and expressed concern about the space charge calibration.

·      Drilling finished yesterday.

·      Readiness checklist update for physics available. Shift crew started to follow normal operation procedure. (observation: a lot of not experienced shift crew and new trainee this year.)

·      Shift operation. One of the DO failed the training exam (Oxygen Deficiency training) multiple times. The DO had to contact training coordinator and just showed up with training finished.

 

§  Plans

·      Gene will analyze the first run this morning for studying the background.

·      VPD: tac alignment will be next when we have collisions.

·      FST will switch back from 9 time bin to 3 time bin.

Plan for this week,

·      111x111 bunch collisions for experimental commission overnight.

·      Maintenance today 08:00 to 17:00; machine development Tuesday.

                          

§  STAR status

·      The VPD earlistTAC was chopped off at 1950 (max). Since Run 25119110, global timing was moved by 2.5 ns early (Find delay 117 to 112). We might need another CAL SCAN to see with collisions. Endcap needs to scan anyway.

·      EPD trigger timing - one clock late, status: Eleanor find a blank VT201. ZDC, BBC, VPD need to revert back to original parameters.

·      ZDCSMD issue (west horizontal channel 4 was hot) and power cycle MXQ crate didn’t work. ZDCSMD gate scanning done, and default values are not changed. Hank: take another Ped run before evaluating this.

·      Running since last evening, pp_200_commissioning. Details about elevating to physics triggers will be discussed at the Trigger Board meeting.

·      L4 calibration. Diyu has received the calibration file from Gene from Run 15. Will investigate.

·      Drilling seems to be in the IR only. All evaluation were done. Lijuan: we should have this discussion early for next time.

·      VPD: tac alignment will be next when we have collisions. Will redo the voltage scan too. Call Daniel and Frank.

·      Previous Issues:

·      Running since last evening, pp_200_commissioning, with MB trigger (BBC+TOF0) and high multiplicity trigger (with TOFMult4 > 8 for QA purposes for now). Fast Offline data has been requested and running for Prithwish, Shengli, et al. Shengli already produced QA plot which looks reasonable. Discussion tomorrow at the Trigger Board meeting.

·      L4 issue seems to be improved by Diyu with space charge calibration update [1]! Flemming suggested Diyu to consult with Gene about the pp 200 parameter for space charge calibration. Currently DCAz still looks strange.

·      Previous Issues: 1) L0L1 turn-off issue, 3) low rate with QT crate in issue (not solved yet). Update from Jeff, Tim, Hank (after yesterday 11:30am discussion)?

·      Aihong ZDCSMD work finished and currently still analyzing the data.

• L0L1 VME crate crashed when running the tune_2024_prepost. Experts may look into it.
• EPD is on now. EPD reduced the QT threshold to 3, and can bring it back to 35 after the scan. 
• Same as yesterday but we may have access later. 
  
  • (access needed) EPD status: Mike: there are yellow and right lights on the TUFF box, need to look into what they mean. (Everything is fine.)
  • (access needed) EPD cooling: fan blowing to the fee box needs to be improved. Prashanth is working on it. 
  • (access needed) ESMD issue, crate 85? Will: the issue is on the electronics or could be water flowing, but not understood yet. Someone can try to clear the bubbles by removing the quick release, etc…Prashanth/Will will email Bill to follow this up and try when we have access again. 
  • FST time bin shift. Ziyue will do it (Monday) and keep the shift crew posted. Jeff will adjust some setting and will document it on shiftlog.

 

Plans

• Jeff will investigate the system with L0/L1 and L2. 
• Whether VPD should be on or off during single beam, experts will monitor and advise.
• APEX mode for running single beams with the tune file. 
• Readiness checklist update for physics next week.
• May 14^th (Tuesday), RHIC will open for Linda H (DOE office of science)

  • FST time bin shift. Ziyue will do it (Monday) and keep the shift crew posted. 
• L2 died couple of times and experts (Hank, Akio, Eleanor) helped fixed it (eliminate the prepost seemed to fix the issue). Christ will look into it. New instruction here, https://www.star.bnl.gov/public/trg/trouble/L2_stop_run_recovery.txt). 

 

Plans

• Jeff will make a different tune file without prepost for now. Run with prepost as the default tune file, but without it will be the plan B.
