Abstract

The performance parameters, the implemented design, and the testing processes used to develop a variable profile scan mirror mechanism for operations in a cryovacuum environment are described. Particular attention is given to the mechanical design of the mirror mechanism, the electrical control system, and the synchronization pulse generation. The results of scan mirror performance tests are presented, showing that the mirror has met or exceeded all performance requirements. The scan mirror has operated at 30 K with a high reliability in positional accuracy and constant velocity scanning for an estimated 700,000 cycles.
