A method of ion transmission coefficient determination for transfer fr
om the source, where ions are produced, to the collector of the electr
on multiplier has been presented. In the measurements, the ions produc
ed from He, Ne, CO, Ar and SF6 on bombardment by electrons with energy
80 eV were utilized. All measurements were performed at the same pres
sure inside an ion source collision chamber. On the basis of the resul
ts obtained, a practical formula enabling one to correct the values of
the measured ion currents has been determined.
