Ideally suited for reflectron mass spectrometer

The F4294-09 is an MCP assembly dev eloped for reflectron mass
spectrometers. In spite of ha ving a center hole f or beam line, the
F4294-09 eliminates ringing phenomena which have been a
problem with conventional MCP assemblies with a center hole.
The F4294-09 thus makes high-speed ion detection possible.
This allows a significant size reduction in the TOF mass spec­trometer and a dramatic improvement in mass resolution.
