The F4655-13 MCP assembly is an ideal detector for high resolution

TOF-MS (time-of-flight mass spectroscopy) because of a two-stage

MCP with 4

µm channel diameter. Our own advanced technology in

optimizing MCP design allows obtaining an excellent output wave-

form with negligible ringing even when detecting very high-speed

signals. The dimensions are exactly the same as the F4655-10 MCP

assembly, ensuring a compact configuration and easy handling.
