In an era of digital transformation and collaborations, the Web Information System (WIS) becomes an essential requirement for the information and data sharing of large experimental facilities among users. With the enhancement in the capabilities and performance of web technologies, sharing of experimental data using a flexible, modular, secure, and robust mechanism is feasible. In this direction, the Large Volume Plasma Device (LVPD), an experimental device dedicated for carrying out investigations for unfolding physical phenomena of relevance to Earth’s magnetosphere and fusion plasmas, also adopts web-based electronic record keeping for its operation. The nature of investigations is concerned with plasma turbulence of electron scale, induced anomalous plasma transport and mitigation of energetic electrons by excited whistler turbulence that requires large scale, and simultaneous multiple point measurements from different electrostatic and electro-magnetic diagnostics. This paper discusses the WIS implementation in LVPD for the experimental configuration, information logging, and preliminary data analysis. The architecture of the system is spread over three tiers covering application, data, and presentation layers. The presentation layer is developed using the Angular 2 framework on the progressive web application architecture. The application and data layers are developed using NodeJS and PostgreSQL, respectively. The novelty of this paper lies in the integrated application development approach and applicability of the latest web technologies in the scientific and experimental domains. This paper discusses the literature survey of similar developments at other places, requirements, scopes, development artifacts, adapted tools and technologies, obtained results from actual plasma discharges of LVPD, and future enhancements.

This paper discusses the salient features and plasma performance of the newly installed Large Area Multi-Filamentary Plasma Source (LAMPS) in large volume plasma device–upgrade. The plasma source is designed to exhibit a plasma electron density of ∼1018 m−3, low electron temperature (∼eV), and a uniform plasma cross section of 2.54 m2. The directly heated LAMPS emits accelerated primary energetic electrons when it is biased with a negative discharge voltage with respect to the anode. The hairpin shaped tungsten ( W) filaments, each of diameter 0.5 mm and length 180 mm, are heated to a temperature of 2700 K by feeding [Formula: see text] to each filament. The LAMPS consists of 162 numbers of filaments, and it has been successfully operated with a total investment of 50 kW of electrical power. The LAMPS as a laboratory plasma source is characterized by large operational life, ease of handling, better compatibility to high pressure conditions, and advantages over other contemporary plasma sources, viz., oxide coated cathodes, RF based sources, and helicon sources, when producing plasma over large cross sections and fill volumes. Pulsed argon plasma is produced with quiescence ([Formula: see text]) using LAMPS for the duration of 50 ms and a reasonably good radial uniformity ( L n = 210 cm) is achieved. Good axial uniformity is also observed over the entire length of the device. Initial measurements on plasma parameters have yielded plasma density of [Formula: see text] with existing set of filaments. A plasma density of ∼1018 m−3 is envisaged for larger thickness of filaments, such as 0.75 and 1.0 mm, with the existing plasma source assembly setup.
