Abstract | In this work the average current per cathode spot (CS) and the velocity of CS motion in a short low-current vacuum arc was investigated on electrodes of Molybdenum, subjected to a magnetic field. The study was performed on electrodes of 30mm in diameter and 2mm gap at arc currents up to 300A. Two components of the external magnetic field were varied independently. The axial magnetic field (normal to the cathode plane) Bn was varied from 0 to 0.1T and the transverse magnetic field (tangential to cathode plane) Bt was varied from 0 to 0.3T. The dependence of the average current per CS on the magnetic field amplitude and its inclination to the cathode surface was found. The average current per CS was found to raise with Bt the slower the greater the Bn value. The CS velocity was found to be proportional to Bt in case the current per CS at certain magnetic field value doesn't exceed the arc current. At fixed arc current the CS velocity saturates with Bt. The Robson angle was found to be proportional to the magnetic field vector inclination to the cathode surface angle with a factor of ∼0.5. The results obtained were compared with the data in references. |

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.
