MCP:End Spoiling
End spoiling in MCPs refers to the deposition of electrode material into the pore by up to several pore diameters at the output surface of the MCP. This technique helps focus the electrons exiting the MCP, reducing their transverse velocity. End spoiling on the output side increases spatial resolution but decreases gain.
Note:
There is a trade-off between spatial resolution and gain.
- Higher End Spoiling = Higher resolution.
- Lower End Spoiling = Higher Gain
The input side end spoiling is usually around 0.5d.
- The input side End Spoiling is usually fixed
The output side end spoiling is around 0.5d - 1.5d.
- for imaging grade: 1.0 - 1.5d
- for detection grade: 0.3 - 0.7d
