AVT Custom UHV Design and Build Products Showcased

Posted on: May 2, 2018

One of the great aspects of designing and manufacturing custom UHV products is working with Scientists and Engineers to solve basic UHV design challenges. Even simple solutions sometimes provide great value in the UHV environment!

John Kestell was upgrading a spectroscopy instrument for his lab at BNL. He required a custom window mount for UHV that provided a 7 degree "tilt". This would increase the efficiency of light transmission by 20 percent – a huge improvement for his system.

His request required mounting a K-Br ("salt") window at 7 deg from parallel in a CF port. The Applied Vacuum Division proposed a simple and flexible solution, which we were able to provide quickly and economically.

The customer's original plan required a custom "cube" with 7 degree faces, but the Applied Vacuum Division proposed a better alternative which would work in their UHV system. Our design provided the same function, but saved about $6k compared to the custom cube approach. Also, the UHV window is easily changed as required for other spectroscopy systems.

“I sent you a crude drawing for my idea, and you came back with a really elegant design that looked even better in real life. One of the innovative features of the system was the custom fabricated 7 degree flange for the window, which is working beautifully."
