| 内容記述 | Time-of-flight (ToF) mass spectroscopy for electrospray thrusters was constructed to investigate the species and fraction of ions in the beam and the presence of fragmentation, where a cylindrical shield was placed just in front of the collector. The shield was expected to prevent the detection of secondary species, which were recently found to be one of the vacuum facility effects. However, the shield seemed to have almost no effects on the ToF signals because the signal did not decrease to zero, and some particles were always detected as they had been detected without the shield. To examine the cause of this signal detection, the collector current was measured under the condition that the gate electrode completely blocked the ion beam. The results implied that the electrospray ion source also emitted some neutrals. The measurement system was reconstructed to detect ions using a high-speed amplifier to avoid neutral particle detection. Then, the results showed that the electrospray thruster was operating in the pure ion mode. | |||||||||
