SiLC beam test - CERN SPS June 2008
8 modules, HV=100V, 40MHz, 6 samples, hor stage :=+2 mm
trigger: 9 mm opening, TLUControl.exe -d 10 -a 12 (now for real)
telescope: zero supressed, new firmware

- long break in the middle due to power outage after thunderstorm

horizontal position ("target") = +2.0mm - after we decided to scan the whole area in 3 steps
this is RIGHT position

all 3 positions are:
RIGHT: +2.00 mm    <--- this run
MID:   -2.75 mm
LEFT:  -7.50 mm

trigger: 9 mm opening, TLUControl.exe -d 10 -a 12

right from the start: no beam...

Very simple alignment (manual linear x direction shifting only, no rotation, assuming equal z spacing) and tracking.
Reference plane = Module 3 (~center)
Deviation calculated from track prediction using the other layers.
Simple Center-of-gravity algorithm (as of APVDAQ_Analysis), no eta applied.
Using only events which have exactly 1 hit per plane (~80% of all events).

Results: 
 Residual RMS = 4.99 um (REFERENCE against neighbor layers 2+4 only)
 Residual RMS = 6.35 um (REFERENCE against all 7 other layers) -> needs more sophisticated alignment

• The first is zero supression an cluster finding done with "apvdaq_analysis_fadc" (Labwindows/CVI application)
  
• The second stage is hit time reconstruction done with ROOT. (hitfit)
  

• start apvdaq_analysis_fadc within the virtal Windows XP machine (parallels).
  
• select a runfile, e.g. run0001.dat
  
• select a propper calibration file, default is "cal002.out"
  
• select pedestal correction file, default is "pedcorr001.ped"
  
• enable "generate hit file and save results"
  
• click "Start"
  
  
• The result of the analyis is a file containing all hits above threshold, the filename is "xxxxxxx_cluster.hit", where xxxxxxx is the run name
  
• The data structure of the file is described at http://elog.hephy.at/testbeam-SPS08/04
  
• The file is located in the same folder as the raw data file (= data)
  

• Once apvdaq_analysis_fadc is finished, start a console window and change into the directory /Volumes/Data/eudet/APVDAQ
  
• execute ./hitfitrun nnnn, where nnnn is the run number
  
  
• results: file with fitted hits (data structure see http://elog.hephy.at/testbeam-SPS08/04) as well as several plots.
  
• file name: xxxxxxx_cluster.hit.fit, the file is located in the subdirectory output.
