We present experimental results of the trace argon impurity puffing in ohmic plasmas Aditya-U tokamak performed to study transport behaviour. Argon line emissions visible and Vacuum Ultra Violet (VUV) spectral ranges arising from plasma edge core respectively are measured simultaneously. During experiments, space resolved brightness profile Ar1+ at 472.69 nm (3p44s 2P3/2-3p44p 2D3/2), 473.59 4P5/2-3p44p 4P3/2), 476.49 2P1/2-3p44p 2P3/2), 480.60 4P5/2) recorded using a high resolution...
This paper discusses the salient features and plasma performance of newly installed Large Area Multi-Filamentary Plasma Source (LAMPS) in large volume device-upgrade. The source is designed to exhibit a electron density ∼1018 m-3, low temperature (∼eV), uniform cross section 2.54 m2. directly heated LAMPS emits accelerated primary energetic electrons when it biased with negative discharge voltage respect anode. hairpin shaped tungsten (W) filaments, each diameter 0.5 mm length 180 mm, are...
Nascent observations about the influence of kinetic instabilities on electron cyclotron emission (ECE) from runaway electrons (REs) have been detected and explored at Aditya-Upgrade (Aditya-U) tokamak. The developed broadband ECE radiometer system offers wideband measurements by integrating several radio frequency units with a fixed intermediate receiver multiple channels, which is novel approach to meet needs localized various toroidal fields extend dynamic range. low density (ne ≤ 1 ×...
