COT Design
- Basic Cell :
- 12 sense ,17 potential wires
- 40 ? diameter gold plated W
- Cathode: 350 A gold on 0.25 mil mylar
- Drift trajectories very uniform over most of the cell
- cell tilted 35 o for Lorentz angle
- Construction:
- Use winding machine
- 29 wires/pc board, precision length
- Snap in assembly fast vs wire stringing
- 30,240 sense wires vs 6156 in CTC
- Total wires 73,000 vs 36,504 in CTC
