WebAlthough they are technically the most complex EP systems, ion engines like those outlined above and shown in Fig. 5 have been the most thoroughly developed and tested of all EP devices. Their appeal stems primarily from their maturity, demonstrated long lifetime (>20,000 hr), relatively low beam divergence (<20 deg) and high efficiency (65%) at a … Web22 dec. 2024 · Ion thrusters generate beams of fast ions that may interact with the facility walls and equipment. These high-velocity ions cause sputtering when hitting the walls of the chamber or all other components located inside the chamber. In ion propulsion test chambers, dedicated beam dump targets are used for reduction of sputtering effects. bio acrylfarbe
