Ion energy analyzer
WebSecondary-ion mass spectrometry ( SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting … Web29 dec. 2004 · We describe a particle analyzer for the energy range between a few electron volts and several thousand electron volts, which is sensitive to single ions and has an inherent time resolution of less than 50 mμsec. Experimental results are given for both energy and mass analysis of positive ions ejected by a pulsed‐arc plasma gun.

WebThe ion dynamics in the high-voltage sheath of a capacitively coupled radio-frequency … WebThe quadrupole mass analyzer propels ions using opposing RF and current fields at its poles. A quadrupole mass analyzer works by combining a radio frequency (RF) alternating current (AC) potential with a direct current (DC) potential over four electrodes, or poles, to create the electric field that sample ions pass through.
WebA simple model is included to provide for an estimate of the ion cloud radius based on ion m/z, ion z, and ion trap operating conditions. The model predicts that singly charged ions of 1 MDa and thermal energy can be contained in the ion trap at the maximum low-mass cutoff, although such an ion would not be detected efficiently. WebThe principal concept of this analyzer is conversion of a divergent charged particle beam …
