Vacuum Feedthrough
Exhibit no. 850
The operation of a vacuum instrument, such as a mass spectrometer often requires the transmission of electrical currents, voltages or signals across the walls of vacuum chambers. This is possible with electrical feedthroughs.
They often consist of ceramic-to-metal assemblies, where the ceramic serves as an electrical insulator between the conductor and the connection flange. In addition to providing leak-tightness in high and ultra-high vacuum, some feedthroughs are resistant to high temperatures used during bake-out cleaning.
The exhibit comes from a triple quadrupole TSQ manufactured by ThermoQuest Finnigan in 2001.
