	With the development of synchrotron radiation technology, an actuator with sub-nanometer resolution, 100N driving force, and compatible with ultra-high vacuum environment is required. To achieve synchrotron radiation micro-nano focusing with adjustment resolution of sub-nanometer and high-precision rotation at the nano-arc level, most of the commercial piezoelectric actuators are difficult to meet the requirements of resolution and driving force at the same time. The flexure-based compound bridge-type hinge has the characteristic of amplifying or reducing the input displacement by a certain multiple, and can be used in an ultra-high vacuum environment. According to this characteristic, the bridge-type composite flexible hinge can be combined with commercial piezoelectric actuators, to design a new actuator with sub-nanometer resolution and a driving force of 100N. This poster mainly presents the principle of the new actuator, the design of the prototype and the preliminary test results of its resolution, stroke.

	Thermal deformation is a key influencing factor in the surface shape of optical components for beamline optics. In the process of beamline design, it is necessary not only to select different cooling schemes based on thermal loading conditions but also to extensively optimize the parameters of these cooling schemes. The traditional approach for optimizing cooling scheme design often requires significant manual effort. By integrating existing experience in optimizing cooling scheme designs, this study transforms the parameterized design tasks that were originally performed manually into automated processes using software. This paper presents the latest advancements in the automated design software for cooling schemes of beamline optical components, and the results indicate that the optimization outcomes of the existing automated design software are close to those achieved through manual optimization.
