1. UCB Progress with 8” MCPs and Testing
8” electroded MCP in the open face test detector.
MCP #3 and MCP #2 have been electroded on both sides with 1700Å inconel.
#2 is 31kΩ and #3 is 3MΩ in air - will do vacuum tests shortly.

2. 8” Open Face Test Detector
Everything except the mounting plate for the 8” open face test detector is done.
The cross delay line is exactly as models predicted, ~250ns delay. We expect to
Achieve <200µm spatial resolution for evaluation of 8” MCPs. All the electronics
is in place for data recording.

3. 8” MCP Test Detector Vacuum System
Vacuum test chamber system for testing the 8” MCPs is finished and undergoing commissioning tests.
