Coordinate Detector

• Report by E. Jensen on the rates in the coordinate detector.
• Study of resolution by Mark Jones
  • Point target with 4.6 GeV electrons. Front face of calorimeter is 526cm from target.
  • 3 planes of scintillator planes with 0.5cm thickness, 134cm long and 3cm width.
  • each plane is 268 bars iwth the middle plane offset by .25cm
  • No 15cm absober block in front. (need to add).
  • Throw electron for vertical and horizontal angle of +/-0.1 radians. (Needs to be larger to cover detector)
    • Plot of energy loss.
    • Plot of number of bars hit with 3 MeV threshold.
    • Plot of Measured minus predicted vertical position.
