TUPYP037	Mechanical Design of Multilayer Kirkpatrick-Baez (KB) Mirror System for Structural Dynamics Beamline (SDB) at High Energy Photon Source (HEPS)	82

	SDB aims in-situ real-time diagnosis in dynamic compression science and additive manufacturing. Nano-experimental environment requires highly multilayer KB mirror system in thermal deformation and stability of mechanism. This paper illustrates the KB cooling scheme and mechanical design. Only using variable-length water cooling to control the temperature and thermal deformation of mirror has limitations here. First, the installation of cooling system should be non-contact so that the surface shape can be sophisticatedly controlled without deformation of chucking power. Second, the distance between the HKB and the sample stage is too small to arrange the cooling pipe. Third, the KB mirror has multi-dimensional attitude adjustment. Cu water cooling pipe would be dragged with adjustment thus it has to be bent for motion decoupling, which occupies considerable space. Thus, the Cu cooling block and water cooling pipe are connected by copper braid. Eutectic Gallium-Indium fills a 100 ¿m gap between the cooling block and KB mirror to avoid chunking power deformation. Finally, the structural stability and chamber sealability is analyzed.

TUPYP040	Experimental Setup Design of Hard X-ray Coherent Scattering (HXCS) Beamline at HEPS
	Z.N. Ou, R.Y. Liao, S. Tang, X. Wang, H.H. Yu, L. Zhou IHEP, People’s Republic of China
	The HXCS is a dedicated coherent beamline of the High Energy Photon Source (HEPS). The experimental setup of the endstation mainly includes two devices: CDI/WAXS XPCS and SAXS XPCS. To achieve high stability requirements, the CDI/WAXS XPCS device use a nano-focusing AKB mirrors system, which will focus hard x-rays to a focal spot as small as 100 nm with a small working distance of 64 mm. In the narrow working distance, AKB mirror chamber and sample chamber are designed as a unit but separated from the middle. And the device is designed with two sets of switchable sample table, in order to flexibly carry out four coherent techniques. Due to high stability, the CDI/WAXS XPCS device is stringent designed for high stiffness, high temperature stability and metrology. Besides, the other important equipments of the beamline include a 1.5m WAXS tube and a 14m SAXS tube. For high-resolution applications, the WAXS tube can be rotated around the sample in the horizontal and vertical plane by 45°and the SAXS tube can adjust distance and angulation. At present, the whole experimental setup is designed according to the fine mechanical design which can meet the experimental requirements.

	Nano-KB/AKB mirrors are used to focus spot size to the nanometer level in main performance beamlines at HEPS, including the Hard X-ray Nanoprobe Multimodal Imaging Beamline(NAMI Beamline), the Hard X-ray Coherent Scattering Beamline(HXCS Beamline), and X-ray Absorption Spectroscopy Beamline(XAS Beamline), etc. For the typical Nano-KB/AKB mirrors mechanical system, a common design of the mounting and clamping mechanisms and the adjustment mechanisms is presented. There are also the key components of the Nano-KB/AKB mirrors mechanical system. Currently, through the design and optimisation of the mechanical structure and the corresponding finite element analysis(FEA), the first Nano-KB mirrors mechanical system at HEPS has been fabricated, and the large travel range, high resolution and high stability adjustments mechanisms are achieved, the slope error of the Nano-KB mirrors is well ensured simultaneously, and the test results are consistent with the design.

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.

	Funding: This work is supported by the project of High Energy Photon Source (HEPS). Positioning measurement is regraded as an effective way for the position compensation and feedback of nano-experimental apparatus. However, it usually suffers many restrictions from the complicated applied occasion of a typical performance beamline for next-generation synchrotron radiation light source. To deal with the problem, a compact direct measurement method based on grating interferometers is presented. The principle, configuration, experiment are designed and implemented for the verification of the feasibility. It performs a high resolution in orthogonal/lateral direction relative to laser beam, which can overcome an infeasible shortage of a typical interferometer for direct lateral positioning. So, it is used for positioning measurement & compensation between KB mirrors and nano-stages of a sample for the experiments of CDI, bragg-CDI, pytchograph, XPCS, etc. Compared with the existed methods, huge frame, two vacuum chambers restriction, multi-axis interferometer and benchmark relay are avoided for the compact system by using proposed method.
