A Optimizing MCP Position Resolution: Latest Research and References"

[BillKet]

Hello! I am doing some calculations and I would like to use the best value for a micro channel plate (position sensitive) position resolution to date. I don't care too much about the details, but I don't want to use too small of a value and of course I'd like to give a reference for this value. I found papers showing 50 microns. I also saw claims below that, but not an actual paper showing it experimentally. Does anyone know of an experiment going below 50 microns? Also, are there detectors better than MCP in terms of position resolution? Just to clarify, I am interested in electrons/ions detection (in my case the energies are between 1keV and 1MeV, but I am fine with references for higher energies, too). Thank you!

At higher energies, silicon detectors are better (~10 micrometers are typical, better is possible). They might still respond to low energy particles.

How are your particles arriving at the detector and what direction do you need to know about? There might be some nice geometric ways to improve the effective resolution.

Also, what's the area and budget you work with?
