APPLICATION
TOF-MS (Time-of-flight mass spectrometer)
The F4655-13 MCP assembly is an ideal detector for high reso-
lution TOF-MS (time-of-flight mass spectroscopy) because of a
two-stage MCP with 4
m channel diameter. Our own advanced
technology in optimizing MCP design allows obtaining an excel-
lent output waveform with negligible ringing even when detect-
ing very high-speed signals. The dimensions are exactly the same
as the F4655-10 MCP assembly, ensuring a compact configura-
tion and easy handling.
