Arradiance 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 50,000 gain @ 1000v• Tested as a single MCP + Phosphor• High resolution images and scrubbing progress.

• Multifiber pattern fades as the MCP gain is increased
• Gain is quite uniform

SSL-UCB, ALD/Incom MCP Test
• We can see the 40µm pores
• We can see the Hex boundary distortions are uneven
• 800v MCP
• 2900v screen

ALD/Borosilicate MCP TestWe can see the Hex boundary distortions cause gain nonuniformity

Note: no pre-vacuum bake
Quite stable after 0.03 C/cm2,
vs 0.2 C/cm2 for normal MCP
