Abstract

A new technique for the capture of external ions by an FT-ICR ion trap is suggested. Ions produced from atoms of low ionization energy collide with one of the trapping electrodes of the ICR cell, lose energy without neutralization and are captured. The surface of the trapping electrode must have a high enough work function. The probability of ion capture was investigated as a function of the ion energy and cell geometry parameters.
