Introduction
This document describes the goals of the data monitoring that will be carried out during the fall 2014 commissioning run of Hall D.
Raw Data
- These questions are for every detector system: TAGH, TAGM, CDC, FDC, SC, TOF, BCAL, FCAL, PS (Pair Spectrometer)
Commissioning Tests
- Are the detectors working?
- Do all of the channels have hits?
- What are the hit counts/rates per channel?
- Are the energies & times OK, garbage, or out of range? (by channel)
- Can we read data from tape?
- Can we reproduce the online histograms with offline data?
Offline Monitoring Plan
- Pull key data/histograms from online histograms, put data in database, make history & plots viewable on webpage
- Periodically test that we can reproduce online histograms using on-tape EVIO data.
Action Items
- David: Online data monitoring environment (RootSpy, hdview2, etc.)
- David is updating RootSpy and its documentation/instructions.
- When he's finished, he'll contact the different detector groups and remind them to write their online monitoring plugins.
- Make sure online monitoring histograms are archived somewhere.
- Detector groups:
- Writing the monitoring plugins for their systems.
- Determining which plots are the primary plots (most important for shift-takers) and which are diagnostic plots.
- Integrating their histograms into RootSpy.
Reconstruction Quality Monitoring
Commissioning Tests
- What is the calibration quality of each system?
- Can we perform reconstruction for each system? (Tracks, showers, etc.)
- Are there any regions of the detector where reconstruction is inefficient?
- Are tracks being properly matched to hits in the other detectors?
- What is the quality of the particle ID?
Offline Monitoring Plan
- Periodically submit jobs to monitor calibration & reconstruction quality of data on tape.
- Just a file or two from each run.
- Periodically: Either some fixed-time interval (every 2 weeks?) or perhaps after big changes.
- Save key data in database, make history & key plots viewable on webpage
- When ready to do full reconstruction, run calibration & reconstruction quality plugins on all files, save key data to database & make viewable on webpage.
Action Items
- Paul: Will integrate the monitoring_hists plugin (reconstruction) plots into RootSpy.
- Will run full reconstruction over a small % of online data.
- Detector groups:
- Writing the calibration scripts/programs/plugins for their systems.
- Determining which plots are the primary plots and which are diagnostic plots.
Analysis Quality Monitoring
Commissioning Tests
- Can we see π0 peaks
- Can we see simple final states
- γ p → p π+ π-
- γ p → p π+ π- π0
- γ p → p π+ π- η
Offline Monitoring Plan
- Periodically submit analysis jobs to study π0's and simple final states.
- Make key plots viewable on webpage.
