TT Alignment

A. Chukanov, Yu. Gornushkin,

S. Zemskova

LNGS, 27th of April 2007

dubna s group activity
Dubna’s group activity
  • Muon track reconstruction (TT alignment, brick finding)
  • TT alignment
  • Measurement of TT efficiency
  • Study of PMT pedestals stability
  • TODO study of PMT signals stability (gains)
tt alignment with the help of muon tracks
TT Alignment with the help of muon tracks

Distances

Hits

Main goal – minimization of all distances for all tracks

distances

D vs Y

3 dimension transformation
3 dimension transformation
  • 3 angles – around X, Y and Z axises
  • Shifting along Z-axis (beam line)
  • Shifting along X-axis
  • Non-linearity along strips

conclusion
Conclusion
  • Preliminary TT alignment has been made
  • Relative parameters was obtained
  • Cross-checks and tests are needed
  • Absolute measurements are needed (bricks and TT position)
  • Necessary to measure relative position of TT, DT and RPC
