AbstractA bakeable (200 °C) ultrahigh vacuum 50 Omega coaxial coupling capacitor is described. The capacitor is compatible with the General Radio G874 coaxial standard, has a large capacitance (6 nF) allowing for efficient transmission of both fast pulses and long analog waveforms, can hold off dc voltages of up to 5 kV, and has a bandwidth greater than 2 GHz, allowing coupling of very fast rise-time signals from cathode ground microchannel-plate detectors, often used in photoelectron spectroscopy. The capacitor design also provides a convenient bias tee for applying high voltage to the detector anode.
