Summary: | The thesis aims at building an experimental setup for conducting the boundary
ejection and resonance ejection experiments on wide variety of ion trap mass
analyzers. The experimental setup has two parts namely power electronics
circuits and mechanical assembly. The focus of the thesis is on the electronics
hardware which provides various power sources required for the operation of ion
trap mass spectrometer. The electronics circuits discussed in the thesis have
better performance, flexibility and ruggedness compared to the existing setup.
The traditional power supplies used in ion trap mass spectrometers are all
linear supplies. But one major drawback of these supplies is the high power
dissipation and consequently, the power efficiency degrades. We are trying to
introduce switch mode power supplies to reduce the power dissipation loss and
eventually increase the power efficiency. In the course of the work the
following power supplies have been developed. The supplies are - 1.Constant
current source, 2.Filament base, 3.gating power supply and pulsing circuit,
4.High voltage DC power supply and 5. High voltage RF generator.
