	High Energy Photon Source (HEPS) has a strict restriction on vibration instabilities. To fulfill the stability specification, vibration levels on HEPS site must be controlled. The control standards are highly related with the vibration amplitude of the sources and the distance between sources and the critical positions. To establish reasonable regulations for new-built vibration sources, the decay patterns on ground are investigated on HEPS site for different frequency noises. A series of experiments were conducted using shaker to generate vibrations with frequency from 1Hz up to 100Hz. The vibration attenuation on ground and slab were measured using seismometers and the attenuation law were analyzed. Details will be presented in this paper.

TUPYP027	A Subnanometer Linear Displacement Actuator	laser, synchrotron, vacuum, experiment	70
	S.K. Jiang, X.W. Du, Q.P. Wang USTC/NSRL, Hefei, Anhui, People’s Republic of China
	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.

	The goal of WALS (Wuhan Advanced Light Source) is to build a world -class radiating light source. Chromium-zirconium-copper was chosen as the main material for the entire storage ring vacuum vessels. And magnetron sputtering (PVD) process was used to deposit NEG coating on the inner surface of copper vacuum chamber, which can further improve the performance of the vacuum. At present, the coating laboratory has taken shape as a whole, and has built a standard cleaning platform, coating platform, ultimate vacuum test platform, extraction rate test platform, coating microstructure test process. As for the coating equipment, bias power supply and custom ceramic parts are added to achieve more functions. Different target materials were controlled by multi-electrode control, while experiments were performed on deposited compositions of different ratios of multilayers; Sample tube bias control access during the coating process; Multiple combinations of target materials and bias parameters for the technique have been studied. Coating is currently underway, and specific test results are in progress.
