| Abstract | Cryogenic cooling is an effective method for the removal of impurity species (water vapour) from the glow discharge. Plasma diagnostic measurements were performed in order to study the effect of cryogenic cooling on plasma processes in the glow discharge source. The fundamental plasma processes were investigated by using optical temperature measurements from Fe+ excitation and N2+ rotational emission spectra and physical temperature measurements using a thermocouple probe. Fe+ excitation temperatures were 3500–3900 K. The N2+ rotational temperatures varied between 500–620 K, while the thermocouple temperatures varied between 380–430 K. For all the diagnostic measurements, lower temperatures (about 50–300 K lower) were measured for the cryogenically cooled glow discharge 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.
