Tracker 1 Cosmic Ray Data

1M.Ellis - Tracker PC - 9th December 2008

Nothing new on the hardware side. Hideyuki has generated new decoding

files to correctly describe the mapping for each of the 3 states that we have taken data in with tracker 1 in R8 (original, moved waveguides at VLPC end and then swapped waveguides at patch panel end).

I have now put these into G4MICE (with a corresponding class VlpcCableOsaka2) in order to confirm his analysis of the data.

We will need to modify the official decoding files to reflect this – software workshop next week, hopefully...

3 Sets of Data

Original – 17675 triggers analysed First swap – 5920 triggers analysed Second swap – 4012 triggers analysed.

All plots from original set due to greater statistics.

Data from the 2nd and 3rd sets confirms the results found in the 1st.

Track Fits

Point Efficiency

Station 1: 99.8 +/- 0.1 % Station 2: 99.1 +/- 0.1 % Station 3: 98.4 +/- 0.2 % Station 4: 99.9 +/- 0.1 % Station 5: 98.7 +/- 0.2 %

Predicted track finding efficiency for 4 or 5 point tracks is 99.94 %

Next Steps

Prepare Imperial format decoding files. Prepare for tracker 2’s arrival.

If anyone wants to do more analysis on the cosmic ray data using G4MICE let me know.

The decoding, geometry and calibration files and analysis application are all in G4MICE ready to be used...
