A dual Stage ion engine for high impulse missions
In this paper, the applicability of dual stage ion optics
and in particular of the so-called dual stage ion engine to high
power, high specific impulse missions will be evaluated. First, the
performance limits of conventional two gridded ion engines (GIE)
will be discussed and the advantages provided by dual stage ion
engines reported. The limits of applicability of a dual stage ion
engine will be analyzed analytically and the results confirmed
numerically. The lifetime and performance of a three gridded
dual stage ion engine (DS3G) will be numerically investigated and
compared to those of a conventional GIE assessing for the first
time in the open literature under what condition dual stage ion
optics provide performance improvements over conventional GIEs
and what is its impact on the thruster lifetime. Dual stage ion
engines have been found to be capable of providing higher thrust
density and longer lifetime with respect to conventional gridded
ion engines.

Abstract

In this paper, the applicability of dual stage ion optics
and in particular of the so-called dual stage ion engine to high
power, high specific impulse missions will be evaluated. First, the
performance limits of conventional two gridded ion engines (GIE)
will be discussed and the advantages provided by dual stage ion
engines reported. The limits of applicability of a dual stage ion
engine will be analyzed analytically and the results confirmed
numerically. The lifetime and performance of a three gridded
dual stage ion engine (DS3G) will be numerically investigated and
compared to those of a conventional GIE assessing for the first
time in the open literature under what condition dual stage ion
optics provide performance improvements over conventional GIEs
and what is its impact on the thruster lifetime. Dual stage ion
engines have been found to be capable of providing higher thrust
density and longer lifetime with respect to conventional gridded
ion engines.
