Plasma performance enhancement and impurity control using a novel technique of argon–hydrogen mixture fueled glow discharge wall conditioning in the ADITYA-U tokamak

Publikováno v: Nuclear Fusion, Vol 64, Iss 10, p 106048 (2024)

Effective control of impurities and precise regulation of the fueling gas are supreme prerequisites for optimal operation in any fusion device. Conventional wall-conditioning methods fall short of achieving optimal wall conditioning. Conventional wal

Evaluation of an Oxygen Transport Coefficient in the Aditya Tokamak Using the Radial Profile of O4+ Emissivity and the Importance of Atomic Data Used Therein

Autor: Malay Bikas Chowdhuri, Joydeep Ghosh, Ritu Dey, Sharvil Patel, Nandini Yadava, Ranjana Manchanda, Amrita Bhattacharya, Izumi Murakami, Aditya Team

Publikováno v: Atoms, Vol 7, Iss 3, p 90 (2019)

Oxygen impurity transport in the typical discharges of the Aditya tokamak was investigated using emissivity radial profile of emissivity of the spectral line (2p3p 3D3−2p3d 3F4) at 650.024 nm from the Be-like oxygen ion. This O4+ spectral line was
