F4655-12 is not allowed to be baked.
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.
