ePC2 has been disassembled in order to repair the broken wires. We have looked through run 11 for other hot spots / hot wires that we should check while the chamber is open.

Anode sectors should have 32 wires , I label the wires 1-32. As we go around, in the direction of increasing sector, I start with wire 1 and end with wire 32: Wire 1, Sector 1--Wire 32, Sector 1 -->Wire 1, Sector 2--Wire 32, Sector 2, etc...

Cathode sectors have 16 wires. The same convention is used.

Additionally, anode sectors are denoted with an A, while cathode sectors are denoted with a C.

See the attachment in http://kaon.physics.berkeley.edu/elog/run11/83 for the mapping
