Abstract
A vacuum pressure gauge is described herein. One apparatus includes an ion trap configured to trap antimatter therein in a vacuum chamber, and a controller configured to determine a lifetime of the antimatter trapped in the ion trap and determine a pressure in the vacuum chamber based, at least in part, on the determined lifetime of the antimatter.
Claims20
A vacuum pressure gauge, comprising:
- a controller configured to:
- determine a lifetime of antimatter trapped in a vacuum chamber;
- and
- determine a pressure in the vacuum chamber based, at least in part, on the determined lifetime of the antimatter.

A method of determining pressure in a vacuum chamber, comprising:
- determining, by a controller, an annihilation rate of antimatter trapped in a vacuum chamber;
- and
- determining, by the controller, a pressure in the vacuum chamber based, at least in part, on the determined annihilation rate of the antimatter.
A vacuum pressure gauge, comprising:
- a controller configured to:
- determine a lifetime of antimatter trapped in a vacuum chamber;
- determine a quantity of particles in the vacuum chamber based, at least in part, on the determined lifetime of the antimatter;
- and
- determine a pressure in the vacuum chamber based, at least in part, on the determined quantity of particles.
