This paper discusses the experimental results obtained from the various components developed for a 1.7 MW neutral beam injector (NBI). Several technologies related to fabrication of back plate, extractor grids, high-current filament feedthru’s, heat-transfer elements, ceramic insulators, cryopumps, rectangular vessels and power supplies have been developed in collaboration with the Indian industry. Control experiments on the prototype plasma box are described.

Carboxymethyl cellulose (CMC) + xwt% Ethylenediaminetetraacetic acid (EDTA) (x = 0, 10, 20, 30, 40)-based biopolymer electrolytes (BPEs) plasticised with polyethylene glycol (PEG) were prepared by using solution cast method. Fourier transform infrared (FTIR) spectroscopic analysis shows the complexation of salt, EDTA with the functional groups of CMC. Impedance analysis shows that the sample containing 20wt%EDTA has the optimum dc conductivity ~ 8.95 × 10–5 S/cm at 30 °C with least activation energy ~ 0.25 eV. Temperature-dependent dc conductivity, dielectric properties and ion dynamics have been analyzed to explore the ion transport mechanism. The scaling of frequency-dependent conductivity and loss tangent were analyzed with respect to EDTA concentration and temperatures. Mobility (µ), charge carrier density (N) and ion diffusivity (D) for all samples were estimated and the sample containing 20wt% EDTA shows the optimum values. Ionic transference number (ITN) measurements reveal that ions are the principal charge carriers. Electrochemical stability window (ESW) was found to be ~ ± 2 V for 20wt% EDTA containing sample.
