High vacuum lines and valves should be designed in accordance with the nominal pumping speed of the high vacuum pump. Otherwise, there will be considerable losses in the effective pumping speed due to ...

[Nick Poole] does a lot of custom work with vacuum tubes — so much so that he builds his own vacuum tubes of various shapes, sizes, and functions right on his own workbench. While the theory of vacuum ...

When you need to test hardware designed to operate in the vast reaches of space, you start in a vacuum chamber. NASA’s Glenn Research Center in Cleveland has many of them, but Vacuum Chamber 5 (VF-5) ...

Figure 1. Vacuum chamber (left) and hot bond controller (right) along with a vacuum source for the inner bag and chamber are all connected and ready to run a double vacuum debulk (DVD) process. Inset ...

Ultra high vacuum (UHV) and extreme high vacuum (XHV) chambers provide the pristine cryogenic environment necessary for qubit ...
