The Shanghai Synchrotron Radiation Facility (SSRF) is an intermediate energy, third generation light source located in Zhangjiang High-Tech Park, Shanghai. In December 2007, an electron beam was first stored and accumulated in the SSRF storage ring. Since then the accelerator commissioning and beam line installation had steadily progressed toward routine user operation in May 2009. This article presents an overview of the SSRF design, construction, commissioning and current status of its user operation. 展开更多

We developed a superconducting nanowire single-photon detection(SNSPD) system based on Gifford-McMahon cryocooler for quantum communication applications.Environmental factors which may influence the system performance are intensively studied.Those factors include temperature fluctuations,the ambient magnetic field and the background radiation.By optimizing the bias circuit,the stability of SNSPD system to electrical noise and disturbance was effectively enhanced,thus making it more suitable for field application.A 4-channel SNSPD system with quantum efficiency higher than 4% at the dark count rate of 10 Hz for λ=1550 nm is integrated and applied into a quantum key distribution(QKD) experiment.QKD was successfully carried out over 100 km optical fiber with the final secure key rate of 1.6 kbps and the quantum bit error rate of less than 2%. 展开更多
