Offline Analysis Commissioning
From Hall D Ops Wiki
Contents
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 Monitoring
- 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?
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.
- 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?
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 pi0 peaks
- Can we see simple final states
- γ p → p π+ π-
- γ p → p π+ π- π0
- γ p → p π+ π- η
