	Leak detection is the key to get a good vacuum system. For the dangerous areas, or facility with complicit structure required to be detected online, it is a hard mask to seek for the suspected leaks one after another. After studying the basic principle of helium mass leak detection, design a remote leak detector based on the PLC, as well as multi monitoring cameras, which can achieve successful injection and sniffer probe leak detection in the range of 270 degree. Compared with the manual operation, this device aims at accurately and reliably detecting leak rate, which can greatly provide technique support of online leak detection. And it can bring the value of reducing the labor intensity and ensuring personal safety.

	The construction of the South Advanced Light Source Platform will be completed in 2021. Among them, the high-precision test hall requires that the effective value of the micro-vibration of the foundation be controlled within the vibration range of 25nm, which has already met the requirements of nanometer level. Research at dongguan machinery group, therefore, in view of the high precision testing hall, south of advanced light source is proposed to geological environment factors, carry out detailed geological survey measurement, focus on the advanced light source foundation vibration test, resistance to vibration and vibration characteristics research foundation and anti-vibration scheme research and the advanced light source is the key equipment vibration reduction technology research, through to the light source address of the proposed foundation vibration test, the vibration of foundation design, synchrotron radiation device key equipment comprehensive analysis and research of vibration reduction technology, formed a series of foundation vibration and key equipment solution, for the later construction of the southern light source to lay a solid foundation.

	Funding: National Natural Science Foundation of China 11905231 With the development of high-energy synchrotron radiation light source with high energy, high brightness, low emittance and nano-scale light spot, accelerators and beamline stations have higher requirements for the stability of the system, and active vibration isolation technology has been paid more and more attention. It has become the key technology for the development of major scientific devices (such as high-energy synchrotron radiation light source, free electron laser, etc.) in the future. In this paper, an active vibration control system driven by piezoelectric ceramic actuator with strong adaptability is designed. NI Compact-RIO real-time control system and Fx-LMS adaptive filter control algorithm are used for the active vibration control system. The identification method of input and output channels and the active control module are simulated by MATLAB. And an active vibration control system based on a parallel 6-DOF platform was built for experimental verification. The experimental results show that the designed active vibration control system has a good control effect for low-frequency micro-vibration.

	The design of shield structure for bellow is an im-portant content for the research of beam position monitor (BPM). The bellow shield structure consists of contact fingers and spring fingers. Several alternative schemes for bellow shield were achieved based on BPM detailed structure. The optimal scheme was achieved by the im-pedance simulation analysis with CST. The dimension of the contact finger was decided based on the length of BPM with the stress condition. The C-type string was manufactured and the spring force was measured as well.
