8” 40µm MCP Pair Photon Counting Test
Bottom MCP has corner Missing, 25 MΩ
XDL detector with pair, 0.003” spacer
Top MCP 100 MΩ in air~400MΩ in vacuum
8” 40µm MCP Pair Photon counting Tests
FIRST IMAGE - stripes due to anode/charge cloud too small –fix : have just rebuilt with 0.7mm biasable,spacer. Broken off corner on bottom MCP.
Zoom in – see multifibers
Anode – X, photon pulses
Gain ~106, <500µm resolution

FIRST Gain map – multifiber visible, lots of gain non-uniformity
