A SMALL CYCLOIDAL MASS SPECTROMETER WITH VACUUM VIBRATOR ARC SOURCE

P T RAJAGOPALAN, V S VENKATASUBRAMANIAN

Abstract


The advantages of the cycloidal mass analyser for heteroenergetic ion sources such as the vacuum vibrator arc source are described. The constructional details of a small cycloidal mass analyser and  some results obtained with the vacuum vibrator source are presented. The results indicate that this analyser, compared to other mass analysers of similar dimensions, gives a much higher resolved ion current and therefore is suitable for ion sources with moderate energy spread.

Keywords


Cycloidal mass analyser; Vacuum vibrator arc; Mass spectrometer.
