TPC Pad Plane | |

Last modified: 10:35 Thursday 08-JUN-2000 |
Nominal data on the TPC padplane (See figure: Postscript or GIF) is summarized for convenience, following a short introduction. The basic arrangement of the wires relative to the inner and outer pad rows is shown below schematically (however, the sensitive pads do not actually extend all the way to the ends of the subsectors, and the subsectors are separated by a gap):
Subsector | Row | Radius (cm) |
Pads | Pad 1 fraction |
Pad 2 fraction |
Anode wires | Anode-wire termination |
