    9. Power Update Initial 1000 V spike found to be obsolete for operation Step Voltage of only 200V to 250V across the microdischarge needed for minimum thruster operation Propellant Update Xenon found to be expensive Argon to be used for testing Xenon may be used for final operation Thrust Measurement Mass Flow meter designed and built Mass Flow meter based on Poiseullie pressure drop can encompass flow rates of 0.001 to 5 sccm Methods for measuring exit velocity are being explored

    11. Note: -Include any graphics that would support / explain the requested information. -For safety considerations, a back-up slide should be available to discuss mitigation of unique safety hazards including both controls and verifications.Note: -Include any graphics that would support / explain the requested information. -For safety considerations, a back-up slide should be available to discuss mitigation of unique safety hazards including both controls and verifications.
