  1. Straw DAQ Linux Machine: strawtrack1.fnal.gov Location: Lab 3 Machine not accessible remotely Straw Analysis Linux Machine: ppdilclaser3.fnal.gov Location: Sidet Machine is accessible remotely LOGIN from any linux machine kinit username (ie. kinit hogann) slogin ilcuser@ppdilclaser3.fnal.gov Location of Data files ~ilcuser/straw/arco2/hv1350/ ~ilcuser/straw/arco2/hv1400/ ~ilcuser/straw/arco2/hv1450/ ~ilcuser/straw/arco2/hv1500/ Location of Analysis Files and Executables ~ilcuser/straw/ana/ To run analysis: cd ~ilcuser/straw/ana edit runlist file to indicate data to analyze type: ./mu2eprot.exe and enter 1, or 2 for gas type (1=Arco2, 2=ArEthane) job creates a histogram file “result.his” -1 means to ignore run 0 means to include run Data Files in zero-suppressed text format

  2. Screen Shot of Raw Data (All in Text Format)

  3. Screen Shot of Zero-Suppressed Data (All in Text Format) TDC Slot Number TDC Channel Number TDC Time (counts) Event ID To create zero-suppressed data format, for example, type: cat straw121809.out | awk -f ~ilcuser/straw/zsuppressed.awk >& straw121809.z

  6. Stage 2: Create histograms for track angle correction. Stage 1: Do distance-to-time (X-T) calibration • 1. Loop over all events in all • files in runlist 2. Make list of complementary pairs of hits 3. Use XT calibration histogram to convert time to distance. 3. Mark the drift “sense” of the hits. drift sense = + or - 1 4. Fill in histogram of SOD versus (drift sense)*(track angle) 5. Do simple analysis of where the inefficient hits are in the straw 6. Do simple analysis of where the noise hits are. 1. Loop over all events in all files in runlist 2. Fill histograms used for inverting the distance-to-time relationship. Only works if illumination in straw is uniform. Stage 3: Create histograms for residual in-cell correction. This correction is very small. It corrects for non-linearities in the XT calibration.
