MCP #168/167 Tests

Light transmission #168 Photo #168

#168 and #167 have been used as a pair with a biasable gap of 0.6mm.Visually they have one band of dark/bright multi’s but are otherwise free of center spots, banding in the multi’s, and bright dark multi’s.

Have done quite a few tests but now starting some comprehensive evaluations,Gap effects, timing, background, imaging etc

Photon counting image, Pulse height amplitude distributions,Gap bias ~1000v, anode bias 400v.

MCP gapped stack #168/167 TestsUse 5GHz amplifier and 1 GHz scope on XDL anode to see pulse shape

Upper amplitude pulses selected to showthe ~1 ns pulse width and ~800ps risetime1000v MCP Gap Bias.

Full pulse amplitude/shape, 100v MCPGap bias. Probably dominated by anodepulse attenuation and dispersion.
