Prototype Report
We are still waiting for a prototype counter from McNeal.
Readout Design
Since the last meeting, we had a meeting with Fernando to answer some basic questions. At that meeting we decided on a segmentation of 10, to aid alignment and to simplify fabrication of the circuit board. Since then Chuck has done some work on the design and we reviewed [? his slides] showing the latest version.
