| Abstract | This paper summarizes the primary controller that is based on Siemens S7 PLC for two in-vacuum undulators to be installed at SSRF. The PLC controls a single gap stepper motor with a separate motor for taper control. Position feedback is derived from two SSI linear absolute encoders mounted across the gap at either end of the array to measure taper. All vacuum pump controls are provided along with cooling water control and a separate bake-out controller. This system is designed for Shanghai Synchrotron Radiation Facility, SSRF, a third-generation synchrotron radiation light source, with the total power is 600 KW, energy 3.5 GeV, circumference of 432 meter, and current of up to 300 mA. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
