SOHO MAMA openable cover/vacuum seal mechanismThe requirements, design, and test results of an openable cover mechanism with a high-vacuum seal developed for the Multi-Anode Microchannel Array (MAMA) Detectors, aboard the Solar and Heliospheric Observatory (SOHO) spacecraft. The mechanism, tested in summer/fall of 1991, has completed 1000 test cycles in an inert atmosphere at room temperature and pressure. Measured mechanism performance included: vacuum seal less than 5 x 10 exp -10 torr-liter/second, 103 degree angular range of travel, 20-minute cycle time, and successful latching functions. An openable cover mechanism that provides a clean, high-vacuum seal is vital to the success of a MAMA Detector operating over a full wavelength coverage from 500 to 1600 A.
