MCP ASSEMBLY FOR HIGH RESOLUTION TOF-MS PRELIMINARY DATA MAY 1998 F4655-13 High-speed response MCP assembly ideal for high resolution TOF-MS detector µ m channel diameter Incorporates a two-stage MCP with 4µ 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 waveform 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.
