Run 14 14.x GeV readiness

Updated on Tue, 2014-03-18 16:55. Originally created by jeromel on 2014-03-14 09:47.

A request to produce the 14 GeV data from Run 14 was made. The goal is to assess how many good events (considering a real analysis) we have on tape. In principle after finishing the 200 GeV data taking, we could come back to the 14.6GeV collisions if there still time, within the 22-cryo-week. In order to request more beam time, we would need to have the results before the end of the 200 GeV run.

The parameters are

Analysis:       

R_CP, v1, v2, net-proton kurtosis
Alex will coordinate - analyzers are
- Pandit Yadav     - v1
- Evan Sangaline - R_CP
- Alex Schma       - v2
- Hiroshi Masui    - v2
- Xiofeng Luo      - Net proron Kurtosis
 

Detector needed:

Need TPC+TOF+BBC
- rough TPC calibration needed only: TPC and Twist, as fast as possible (and time constrained to the timeline below) SC&GL, BeamLine as applies, no dE/dx
- TOF rough calibration only (alignment to TPC)

High level timeline:      

To be ready by the end of May

Data sample:    

production_15GeV_2014  340.53 M
Production estimates (Lidia): CPU/evt for auau 15GeV is roughly ~4sec - at 25% of our farm it will take ~10 days

Timeframe

  • Today's date: March 15th
  • Let us assume May 15th all is wrapped up.
  • Analyzer would need at least 2 weeks - let us assume 3 weeks (50% contingency)
    => data needs to be ready in the week of April 23rd)
  • Production taking about 2 weeks would imply a start of production on April 9th
  • We have 3 weeks to prepare ...
  • Best try for calibration need to be limited to 2 weeks from now
    (early target allows leaving some breathing room in case of bad surprises / if we set our minds to 3 weeks, we will miss the target)

We need a status update at S&C meeting as far calibration status goes on the 19th and 26th ... possible the 2nd of April, we should be in good shape.

We need

  • To refine the dataset needed (all data? some streams?)
  • Make sure we have a tester list (names, who's doing what - this may be important for analysis priority, disk space arrangements, ...)
  • The TOF folks need to be on standby - what (timing) calibration can be achieved within 2 weeks?
  • The HFT geometry in Sti sorted out
    Attention: we already had this as a task for the second part of the Run 13 data BUT for Run 14, we now have IST and SSD
    Note: Dmitri aware
