This dataset contains data which are used for generating Fig.7 to Fig.9, and Fig.11 to Fig.16. These figures are plotted using a MATLAB script.

The figures are as follows:

Fig. 7   Thruster 1 endurance test overview (cooling periods omitted for clarity). Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 8   Thruster 1 endurance test second stage: onset of thruster degradation (cooling periods omitted for clarity). Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 9   Thruster 1 endurance test third stage: short-circuiting failure mode (cooling periods omitted for clarity). Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 11  Overview of first 140 cycles of 15 A endurance testing (cooling periods omitted for clarity). Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 12  Overview of last 160 cycles of 15 A endurance testing (cooling periods omitted for clarity). Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 13  Overview of 20 A testing (217 cycles, cooling periods omitted for clarity). Green line indicates a value of 42 mΩ. Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 14  20 A testing between 40000 and 60000 s cumulative heating time (cycles 133-200). Green line indicates a value of 42 mΩ. Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 15  20 A testing, cycles 196 to 214. Green line indicates a value of 42 mΩ. Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
Fig. 16  20 A cycles 208-213, resistance only. Green line indicates a value of 42 mΩ. Upper plot: Tn, nozzle temperature; mid plot: R, thruster resistance; lower plot: Pe, thruster electrical power.
