Status of the Appendices: Pixel Detector

1
Status of the AppendicesPixel Detector

• Four appendices for pixels
• Sensors and Simulation
  Marina, Simon
• Test beam results Pixel group
  (Gabriele,)
• RF shielding studies and RD planChris White of
  IIT, pixel group
• Module Tests Marleiyh, Sergio,
• In CVS there is a draft of the first two
  appendices
• The last three are in word files
• Difficult to say how many pagesat the end of the
  editing

2
Test beam results appendixchapters in CVS

• Introduction
• Experimental setup
• Data analysis
• Calibration
• Landau distribution
• Spatial uniformity charge collection
• Charge-sharing
• Spatial resolution
• Box-like distribution and Non Gaussian tails
• Comparison between detectors
• Threshold and bias (Sharing and Res.)

Test beam results appendixWhat to do

• Only the first part is easy to read, the second
  one can be read
• Merge some chapters together
• Some sentences with test beam results and
  simulation results
• Charge Collection
• Charge-sharing
• Resolution

4
Test beam results appendixSpatial resolution

• Gaussian Width (gt4000tracks)
• No projection error subtracted
• Kalman fit
• Fiducial region
• One track per triggered event
• Improved projection resolutiondemanding cluster
  size 2 in most upstream and downstream X SSD
  planes
• Different PFA
• 8 bits versus 2 bits
• Sharing along column (one example of
  sharing between two columns)

• Target (long term) Dave

We will see what to do about these topics, but it
looks hard to include it.
