Precise alignment of x-ray mirror components utilizing pneumatic actuators

X-ray telescope architectures currently being examined for future missions such as concepts like the International X-ray Observatory (IXO) are composed of thousands of extremely thin mirror elements (0.2 to 0.4 mm thick) arranged in closely spaced arrays. The precise positioning, integration, and testing of those optical elements are some of the fundamental challenges for fabrication of future X-ray telescopes. We will describe a novel pneumatic actuator and initial testbed results for positioning a single mirror and subsequently an array of mirrors.
