Vacuum Flange MCP Detector

An open-type ceramic-to-metal detector based on microchannel plates and a metal anode mounted on a vacuum flange is designed for the detection of single pulses from low-energy electrons in an electron time-of-flight spectrograph.

The detector is mounted on a vacuum flange and connected to the coaxial vacuum leads so that the MCPs can be operated immediately after applying voltage. Flange type is CF-100 conflat. Wiring cables for voltage supply to the MCP are suitable vacuum-tight SHV/MHV. Cable for the output signal acquisition is BNC/SMA. Vacuum tightness of the flange assembly is not less than 10-7 mbar/Torr. A matched load of 50 ohms is used.
