| COMPACT MCP ASSEMBLY FOR TOF (TIME OF FLIGHT) F4655-12 High Speed Detection of Positive / Negative Ion or Electron FEATURES Detection of Positive/Negative lon or Electron High Speed Response High Gain High S/N Ratio High Pulse Height Resolution Wide Dynamic Range Compact and Lightweight APPLICATION TOF Detector TMCPF0068 F4655-12 is the best suited detector for a TOF measurement with positive/negative ion or electron. It allows to detect a charged particles (ions, electron, etc.) having any polarity in a high speed with keeping a high gain and wide dynamic range of F4655 series. Its output will give a high speed output waveform without a ringing. In addition, the potential of output connector can be the ground even an MCP anode is high voltage like an electron detection due to a coupling capacitor, which allows the handling very easy.
