Development of the Top Hat Electric Propulsion Plume Analyzer (TOPAZ): Mass Analyzer Design and Preliminary Calibration Data
نویسندگان
چکیده
The continued development and testing of the Top Hat Electric Propulsion Plume Analyzer (TOPAZ) is presented for high-powered electric propulsion far-field plume diagnostics. TOPAZ incorporates a ‘top hat’ design with an analyzer constant of 100 resulting in a wide energy range and a high energy resolution. The design of the electrostatic and mass analyzer sections for TOPAZ is described. The key performance parameters for the analyzer are compared with theory, and preliminary mass-per-charge measurements on an ion beam are presented. A time-of-flight (TOF) system is incorporated into TOPAZ, and in conjunction with the energy analyzer section, provide a partial velocity distribution function measurement capability.

Several successful Hall thruster plume studies have been conducted at the University of Michigan using a 45degree parallel-plate electrostatic energy analyzer mounted externally to the vacuum chamber. This requires the thruster to be in close proximity to the chamber walls potentially resulting in some set-up induced inaccuracies of the ion voltage distributions. A new design has been developed...

Design and performance of a novel hybrid mass spectrometer is described. It couples a linear ion trap mass spectrometer to an orbitrap mass analyzer via an rf-only trapping quadrupole with a curved axis. The latter injects pulsed ion beams into a rapidly changing electric field in the orbitrap wherein they are trapped at high kinetic energies around an inner electrode. Image current detection i...
