Latest Patents

Birdsey holds a patent for an "Optically pumped direct extraction electron spin filter system and method of use." This invention discloses a system and method for producing a directly extracted flow of preferred-spin-polarization-direction electrons. The optically pumped electron spin filter system utilizes a mixture of alkali atoms and electron polarization direction enhancing buffer gas. This mixture is introduced into a single chamber, where a laser system produces a beam of photons that optically pumps electrons in atoms to a dark-ground state with a preferred-spin-polarization. The system maintains this polarization in the presence of an imposed magnetic field, which is oriented co-linear with the beam of predominantly single polarized photons. Concurrently, electrons are generated in the enclosed space by a buffer gas mediated electric discharge, and they are caused to be in a preferred-spin-polarization-direction via collision mediated exchange mechanisms prior to being directly extracted. Birdsey's innovative approach has the potential to advance the field of electron spin technology.
