Recent TRD reports at the GlueX collaboration meeting
Prototype: requirements and very preliminary design
- Requirements:
- Use existing FDC pre-amps, fADC125, connectors, cables
- Wires and strips at 90 deg.;
- One 24-channel pre-amp for the wires and one pre-amp for the strips.
- Active area sizes:
- 240 mm across wire direction: sense wire pitch of 10 mm
- 120 mm across strip direction: strip pitch of 5 mm.
- Field wires in between sense wires with 10 mm pitch.
- 20 mm drift gap
- Max drift time < 3 microseconds (to be used within the standard GlueX DAQ):
- ~2kV +HV on sense wires, -500V on field wires, -1.4kV on the upstream cathode Garfield field/drift time simulations
- 3D schematic
