Plan for the offline monitor analysis
of the test beam data
IDEA: analysis of a sample of reconstructed (a
step forward after the check made by the online
monitor) events, in a short time, just after the
run is finished
How to implement it ?
Where we are as of today?
Time scale?
Start from
xxx_digi.root
xxx_merit.root
xxx_recon.root
xxx_svac.root
Complete reconstruction of a sample of events is nedeed:
- Tracks: number, directions
- Cal: energy, directions
- Acd: energy
- Trigger
- Ancillary: positions, directions
How many events with the reconstruction?
-it depends on the time between runs
Code will run under root as a simple macro for the
user:
- Open and read output files from Gleam
- Open and read a file with reference histo
- Select type of run:
beam energy
beam angle
particle id
tag
- Plot selected quantities
- Make a comparison with reference histo
(produced using SLAC mass production)
- Produce warnings and/or alarms in case of failure
List of selected variables:
TKR:
Acd:

Cal:
TkrNumTracks
Tkr1FirstLayer
Tkr1Gaps
Tkr1ZDir
DirErr

Trigger:

- GemCondArrTime
We are on writing the code
Expecting to have everything ready (the bulk of the
analysis) for the Pisa workshop
All possible small changes can be discussed in Pisa
and implemented before the TB
