Abstract | Summary form only given. This paper presents a Monte-Carlo model to explain the multipactor discharge and its high power absorption in a dielectric-loaded accelerating (DLA) structure reported recently. Kinematic calculation is performed to determine the susceptibility diagram, which is a useful tool in analyzing whether multipactor discharge will take place over a range of RF and DC electric fields for certain material. A resonant condition of a maximum growth region in susceptibility diagram has teen determined numerically and analytically. The constructed susceptibility diagram is compared with the simple dielectric case. Based on the constructed susceptibility diagrams, dynamic calculations for beam loading and its power absorption by the multipactor discharge are performed. It is found that the fraction of power absorbed by multipactor discharge at saturation is much larger than the case of a simple RF window, and it is sensitive to the incident power, which confirms the prior experimental results. This enhanced power absorption is due to the fact that the length of DLA structure is much larger than the radius of the structure. The difference between the resonant condition (due to phase focusing) and saturation (due to team loading) is clarified. |

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.
