FIG. 1.

SEM photographs of an array of silicon capillary emitters filled with diameter microspheres. The inset is a detail of the capillary tip.

Image of FIG. 2.
FIG. 2.

Current-voltage measurements of single capillary emitters without (top curve) and with silica microspheres (bottom curve). Error bars indicate the standard deviation of repeated measurements.

Image of FIG. 3.
FIG. 3.

Energy density distribution for a capillary without and with microbeads spraying , also referred to as EMI-Im. The smaller energy deficit and narrower energy distribution for the capillaries with microspheres indicate ionic operation, and the broader deficit mixed ion/droplet mode.

Image of FIG. 4.
FIG. 4.

RPA measurements showing the density distributions for a capillary with microspheres for emitter voltages ranging from 600 to 1200 V.

Image of FIG. 5.
FIG. 5.

TOF traces recorded with a 19 emitter array with capillaries having a inner diameter filled with microspheres with an extractor electrode with holes space at from the capillary tip. Current trace as a function of atomic mass assuming the beam voltage to be equal to the emitter voltage. The masses for the monomer and the dimer are marked as dotted lines.
