PRIMARY ION PRODUCTION FROM VARIOUS GASES IN SPONTANEOUS DESORPTION Academic Article

abstract

• The "spontaneous" emission of ions from a CsI surface was studied as a function of the nature and pressure of gas in the experimental chamber. Methanol, trichloroethylene, dichloromethane, and 1,2-dibromohexane were used as gases. In all cases it was observed that the primary ion count rate is a linear function of the pressure. The yield of I- was found to decrease with pressure and depends on the nature of the gas used. The results indicate that the primary ions are being produced by the field ionization of the introduced gas and the field ionization or field desorption of contaminant molecules. 1993.
