Abstract | The production of ultra-short photon pulses for UV, VUV or X-ray Free-Electron Lasers demands new techniques to measure and control the arrival time of the FEL-pulses. For pump-probe experiments using optical-lasers, the desired synchronization between the pump and the probe pulses is on the order of tens of femtoseconds. This corresponds to the typical duration of the FEL pulses. Since accelerators are large scale facilities with a length of several hundred meters or even kilometers, the problem of synchronization has to be attacked twofold. First, the RF acceleration sections upstream of the magnetic bunch compressors need to be stabilized in amplitude and phase to high precision. Second, the remaining electron beam timing-jitter needs to be determined with femtosecond accuracy for off-line analysis. In this paper, several techniques of measuring the FEL beam arrival-time are presented. |

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.
