Abstract

The cooling bender with a flexural hinge-based framework is researched to reduce the crystal thermal distortion. The types and their principles of the crystal thermal distortion are introduced

and the mechanical forces and cooling bender structure are analyzed with the finite element method. The results show that the bender can greatly cut down the thermal distortion of the first crystal

the crystal surface error is only 0.04 μrad3 μrad at the peak power density of 5 N/mm

which is much lower than the design requirement to the beam line in synchrotron radiation. Such kind of bender especially fits in high-heat load

and it is one of the key techniques to solve the problems in developing the third generation of synchrotron radiation light source.
