1. SSL-UCB, ALD/Incom MCP Test
Incom substrate
40µm pores, 8 deg bias, 40:1 L/D
Sent to Arradiance for resistive and emissive layer application + electrode
Resistance approx 750 MΩ in vacuum
Arradiance tests show 50, v
UV - bright image, no light - black!
Tested as a single MCP + Phosphor
It works! We have a functional, uniform, and stable (1hr) MCP using borosilicate and ALD.
Project milestone under 5.1 year 1 deliverable
The sensitivity of the activated photocathode is considerably higher, with a quantum efficiency of as high as 37% at about 450 Å and a sensitivity cut off energy of about 6.2 eV. The observed decrease of sensitivity at 988 and 520 Å (and probably not observed at ~670 Å) is likely to correspond to 2xEgap+Eaff,, 4xEgap+Eaff,, and 3xEgap+Eaff,, respectively. A much better spectral continuity of the illumination source is required in order to study the UV absorption fine structure.

4. SSL-UCB, ALD/Incom MCP Test
Multifiber pattern is bad due to crushing of pores at the multifiber interfaces

5. SSL-UCB, ALD/Incom MCP Test
Multifiber pattern fades as the MCP gain is increased
Gain is quite uniform
Need to determine cause of black spots
Multifiber lines <100µm
