| Abstract | This paper describes the first results of an experiment aiming to determine the frequency dependence of a cryogenic vacuum-gap capacitor between 0.01 Hz (‘DC’) and 1 kHz (AC). The AC-‘DC’ difference of the vacuum-gap capacitor is measured as a function of temperature, and the measured change of around 23 µF/F between 273 K and 4 K agrees well with an extrapolation of earlier measurements on the same capacitor between 100 Hz and 1 kHz. The results also seem to support estimates that the AC-‘DC’ difference of this capacitor is well below 1 µF/F at 4 K. |

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.
