Muon Tracker Key Parameters

Physics Resolution Requirements

Resolve J/ from ' and optimize signal to background.

Resolve (1S) from (2S+3S) over all rapidity (including central rapidity).

Simulation Results

• mass resolution 88 MeV/c²
• J/ mass resolution 100 MeV/c²
• mass resolution 200 MeV/c²

Detector Characteristics and Performance:

• 3 planes, 9 coordinates/station for good track reconstruction and pattern recognition.
• Detector resolution 100 m (rms per cathode plane)
• Station 2 chamber thickness 0.5% of a radiation length.
• Stations 1 and 3 chamber thickness 10% of a radiation length each.
• Minimized acceptance losses from chamber frames at all stations.
