Time-of-Flight Spectroscopy of Hyperthermal Molecular Beams of Alkali and Alkaline Earth Metal Halides
摘要
Abstract
A method for recording time-of-flight spectra of hyperthermal gas-dynamic seeded molecular beams of alkali and alkaline earth metal halides is described. This method is free of the need to determine and adjust spectra taking hardware time delays into account. The method is based on registering ions, which are formed in the collision-induced dissociation (CID) of molecules with ionic bonds, by two secondary-electron multipliers located at different distances from the beam chopper along the beam passage.
