Abstract | Summary form only given, as follows. Non-equilibrium, atmospheric pressure plasma discharges are increasingly being used in various novel applications. In many of these applications, a non-thermal, large volume, atmospheric pressure discharge which can be generated in a practical and economical way is sought. In this context, we present a novel method to produce such a plasma. This method is somehow similar to the dielectric barrier discharge scheme. However, instead of a having a dielectric covering the electrodes, we use a resistive layer to cover at least one of the electrodes. This allows us to operate the discharge with either a DC or an AC source. Using DC or AC (60 Hz) power supplies to drive the electrodes, and helium as the ambient gas we were able to generate large volumes (up to few liters) of plasma. The input power was up to 300 watts. The non-equilibrium plasma generated by this method appears to be diffuse, and uniformly fills the entire volume between the electrodes. The gap between the electrodes is adjustable, and we were able to generate a plasma with gap distances up to 15 cm. In this paper, we report on the current-voltage characteristics of the RBD discharge. In addition, using a photomultiplier tube (PMT), the light emission of the discharge is measured and the PMT signal is correlated with the discharge current signal. Our experiments show that although the discharge is run with a DC voltage, the current signal exhibits a pulsed form with pulses few microseconds wide at a repetition rate of few kHz. |

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.
