Hollow cathode thrust measurement using a target: system calibration and development
Hollow cathode thrust measurement using a target: system calibration and development
The presence of high-energy ions, observed in hollow-cathode plumes, suggests that these devices might be converted into simple micro-ion thrusters. In order to investigate the ion emission, a target system for the measurement of thrust and ion current has been developed by the Astronautics Research Group at the University of Southampton. The cantilever beam target deflection is measured with a laser opticallever, also developed for this purpose. A direct calibration of the target has been performed, confirming that the predictions of the theory of slender beams are verified. This has been accomplished by applying known forces, in the form of weights, to target beams with the same shape but different thickness. An initial version of the measurement system has been set up and two different versions of the T6 ion thruster hollow-cathode are ready to be investigated in a vacuum rig.

Abstract
The presence of high-energy ions, observed in hollow-cathode plumes, suggests that these devices might be converted into simple micro-ion thrusters. In order to investigate the ion emission, a target system for the measurement of thrust and ion current has been developed by the Astronautics Research Group at the University of Southampton. The cantilever beam target deflection is measured with a laser opticallever, also developed for this purpose. A direct calibration of the target has been performed, confirming that the predictions of the theory of slender beams are verified. This has been accomplished by applying known forces, in the form of weights, to target beams with the same shape but different thickness. An initial version of the measurement system has been set up and two different versions of the T6 ion thruster hollow-cathode are ready to be investigated in a vacuum rig.
