Abstract
ABSTRACT The Smart X-ray Optics project is a UK based consortium of eight institutions investigating the application ofactive/adaptive X-ray optics for both large and small scale. The work being undertaken at the University ofLeicester includes the modelling and testing of a large scale optic, suitable for an X-ray telescope. This willincorporate piezoelect ric devices to enable the surface to be actively deformed, aiming to achieve an angularresolution better than that currently available (e.g. Chandra 0.5). The test optic design is based on a thinNickel ellipsoid segment on the back of which will be bonded a series of piezoelectric actuators. Simulation of theX-ray performance and the eect of the actuated piezoel ectric devices on the detected image is described. Detailsof the models produced for the piezoelectric actuation routine and the simulated annealing algorithm under de-velopment, will be outlined. Planed testing of the ellipsoidal prototype and future objectives for implementationof active X-ray optics in the design of an X-ray telescope will be discussed.Keywords: X-ray astronomy, X-ray telescopes, piezo electric actuators, t hin active mirrors
