DOIAbstract
A cross-beam apparatus is described which measures partial ionisation cross-sections of atoms and molecules by electron impact. It incorporates a pulsed electron beam and a pulsed ion extraction system as well as a relative flow technique for determining absolute cross-sections. Details of the measurement procedure and the results of the production of CO+2 ions from CO2 up to 500 eV electron impact energy are presented and compared with other reported measurements
