Paper Abstract

The Smart X-ray Optics project is a UK based consortium of eight institutions investigating the application of active/adaptive X-ray optics for both large and small scale. The work being undertaken at the University of Leicester includes the modelling and testing of a large scale optic, suitable for an X-ray telescope. This will incorporate piezoelectric devices to enable the surface to be actively deformed, aiming to achieve an angular resolution better than that currently available (e.g. Chandra 0.5"). The test optic design is based on a thin Nickel ellipsoid segment on the back of which will be bonded a series of piezoelectric actuators. Simulation of the X-ray performance and the effect of the actuated piezoelectric devices on the detected image is described. Details of the models produced for the piezoelectric actuation routine and the simulated annealing algorithm under development, will be outlined. Planed testing of the ellipsoidal prototype and future objectives for implementation of active X-ray optics in the design of an X-ray telescope will be discussed.
