Analysis of background gas in an alkali-metal vapor cell coated with paraffin
Abstract
Background gas in a rubidium vapor cell coated with paraffin as an anti-spin-relaxation coating was investigated. The cell was opened in a vacuum chamber to release background gas that was analyzed with a quadrupole mass spectrometer. The background gas was mainly composed of hydrocarbons of C3 and higher, as well as hydrogen.
