Abstract :
We describe a focussing mirror system that is bent by differential thermal expansion due to a temperature gradient perpendicular to its surface. Temperature control is achieved through a side cooling arrangement on the top, and a heating device at the bottom of the mirror body. We present measurements of the optical properties obtained by speckle interferometry on a test system, and under actual operating conditions in the white undulator beam.
