Funding: This work is supported by the project of High Energy Photon Source (HEPS). High Energy Photon Source (HEPS) regarded as a new 4th generation synchrotron radiation facility, is under construction in a virgin green field in Beijing, China. The X-ray optics/mirror mechanical systems (MMS) play an important role, which would be expected to be designed carefully and rigidly for the extremely stable performance requirement of HEPS. In addition, there are indeed big challenges due to so many types of mirror systems, such as white beam mirror (WBM), harmonic suppression mirror (HSM), combined deflecting mirror (CDM), bending mirror, Nano-KB, and the transfocator of Compound refractive lens (CRLs), etc. Therefore, overall progress on design and maunfacturing of the MMS is introduced, in which a promoting strategy and generic mirror mechanical system as a key technology is presented and developed for the project of HEPS. Furthermore, ultra-stable structucture, multi-DOF precision positioning, Eutectic Galium Indium (E-GaIn)-based vibration-decoupling watercooling, clamping, and bending have always been prior designs and considerations.

Design of Ultra-Stable and Multi-DOF Generic Mirror Mechanical System at High Energy Photon Source (HEPS) | |
|

The main function of the generic mirror chamber system in HEPS is to support, adjust the pose and provide the ultra-high vacuum environment of the optical elements in the beamline. Its pose adjustment requires micrometer or submicroradian level repetitive positioning accuracy and adjustment resolution. The white beam bending mirror chamber in the generic mirror chamber system of the Hard X-ray Nanoprobe Multimodal Imaging Beamline(B2) is taken as an example, to discuss the design of its pose adjustment mechanism. It needs to achieve 5-DOF for pose adjustment function. This paper proposes using a multi-layer marble structure and a combination of multiple motion mechanisms to achieve this function. The motor and screw-nut pair drive sliders can achieve 2-DOF adjustment. The motor and screw-nut pair drive two wedge-shaped blocks can achieve 2-DOF adjustment. The motor and straight circular flexible hinge drive a disc-type flexible hinge can achieve one angle adjustment. Finally, through series of numerical calculations, finite element simulations and physical experiments, it is demonstrated that the design indexes meet the requirements, thus verifying the feasibility of the scheme. | ||
