| Abstract | Low-Level RF (LLRF) control systems developed for linear accelerator based Free Electron Lasers (FEL) require real-time processing of thousands RF signals with very challenging RF field detection precision. To provide a reliable, maintainable and scalable system a new generation of LLRF control based on MTCA.4 architecture was started at DESY for the FLASH and European-XFEL facilities. In contrast to previous RF control systems realized in 19″ modules, we could demonstrate field detection, RF generation, RF distribution, DAQ system and the high-speed real-time processing entirely embedded in the MTCA.4 crate system. This unique scheme embeds ultra-high precision analog electronics for detection on the Rear Transition Module (RTM) with powerful digital processing units on the Advanced Mezzanine Card (AMC). To increase system reliability, maintainability and reduce performance limitations arising through RF cabling, we developed and embedded in the MTCA.4 crate a unique RF Backplane for RTM cards. This backplane is used for distribution of high-performance Local Oscillator (LO), RF and low-jitter clock signals together with low-noise analog power supply to analog RTM cards in the system. In this paper we present the design and architecture of the MTCA.4 crate with the RF Backplane and successful test results of the LLRF control system. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
