F4655-13
High-Speed Response MCP Assembly Ideal for High Resolution TOF-MS Detector
Incorporates a Two-Stage MCP with 4 µm Channel Diameter
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 4µm 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.
