Description
The Cornell/Purdue prototype TPC, first commissioned in December 2004, has
an active area of 10cm square and a drift length of 64cm. The present
readout includes 56 channels of 14 bit, 105 MHz, flash-ADCs. Revised
readout pad boards, installed in March 2006, include a combination of 5mm and 2mm
pads. Recent studies of various gas-amplification devices will be
discussed. These include Purdue-3M Micromegas, the Saclay produced bulk
Micromegas, and GEMs.
