Abstract
A cold-cathode electron impact ionization source based on field emission fr om an array of diamond-coated silicon whiskers is described. The source is coupled to a micro-scale ion trap mass spectrometer (r(0) = 0.50 mm, z(0) = 0.50 mm). An electron beam of 250 nA could be obtained through the 0.45-mm diameter opening in the end cap electrode.
