Abstract

We have been developing a rotating mechanism to rotate a waveplate in the light beam from a space solar telescope to be flown onboard the next solar satellite mission, Solar-C. Because the performance of this telescope is very sensitive to contaminants on the optical surfaces, the rotating mechanism shall have a low outgassing performance. We are currently evaluating its life-duration performance by operating it in a small vacuum chamber to ensure the number of operations required in the mission life. During this test, we also measured the outgassing rate every month. The data from a run in more than 1 year shows that the outgassing rate from the mechanism is kept low. We confirmed this mechanism could be used under stringent conditions for contaminants.
