Swagelok Ultra-Torr based feed-through design for coupling optical fibre bundles into vacuum systems

We report the design of an inexpensive and flexible fibre-optic bundle high vacuum feed-through that can be constructed from easily available Swagelok Ultra-Torr™ stock parts. The fibre bundle extends through the vacuum envelope and thus does not suffer the transmission losses encountered when using face-to-face couplings. The flexibility of construction allows the fitting to be customised to suit all flange designs such as CF, KF or custom mountings. The use of Viton™ o-rings allows modest baking (max 200 °C) for high vacuum applications and fibre bundles can be easily repositioned, removed or replaced.

High vacuum feedthrough for angular, linear, and rotary motion

An angular motion feedthrough capable of supporting a large diameter linear motion feedthrough has been designed and built for the large experiment on instabilities and anisotropies at West Virginia University. With a combination of linear, angular, and rotary motion, a probe can be positioned in the vacuum chamber within a cone-shaped volume.

A compact small aperture straight-through vacuum valve

A simple, fully screened, high-voltage vacuum feedthrough

A high-vacuum feedthrough is described which is small and simple to construct and incorporates rigorous screening against noise pick-up. Rotary and linear displacements can be transmitted across the vacuum interface by the feedthrough.

An Economical High Vacuum Water Cooled Sputtering Cathode Assembly and Feedthrough

A very economical high vacuum feedthrough and water cooled cathode pedestal and dark space shield assembly were designed and built in our laboratories without requiring any model shop time and without purchasing any expensive material from the outside. The effectiveness of this design to sputter alloys was verified by x-ray spectrographic techniques. During a typical supttering run 5000 V dc at 150 mA could be handled by this cathode assembly and feedthrough without difficulty. This particular feedthrough design was tested successfully in the 10−7 Torr range.
