A Simple Method for Measuring Time-of-Flight Spectra of a Gas-Dynamic Molecular Beam

摘要

A simple and sensitive method is proposed for studying gas-dynamic seeded beams containing molecules of some salts of alkali metals and thallium with ionic bonds. This method is based on the use of dissociation of these molecules induced by collisions with xenon. A secondary electron multiplier serves as the detector of a molecular beam. The proposed method has been tested on a seeded gas-dynamic beam of CsCl molecules at a pressure of the carrier gas (hydrogen) of 1-5 atm and with energies no higher than 20 eV. This method has shown high accuracy and reproducibility of results.
