Production of high-quality plasma discharges via real-time control of plasma current ramp-up using neutral gas injection in Aditya-U tokamak
Suman Dolui, Praveenlal Edappala, Kaushlender Singh +13
Robust control of plasma current ramp-up is an absolute necessity, as an efficient and uncontaminated plasma current ramp-up is essential for achieving prolonged, high-pressure tok…
Development of a thin-target hard X-ray bremsstrahlung detection system to study confined runaway electrons in Aditya-U Tokamak
Suman Dolui, Santosh Pandya, J. Kumar +23
A specially shielded CdTe detector based hard X-ray (HXR) monitoring system equipped with a lead collimator has been developed and installed on the Aditya-U tokamak to investigate…
Plasma Position Constrained Free-Boundary MHD Equilibrium in Tokamaks using pyIPREQ
Udaya Maurya, Amit K. Singh, Suman Aich +3
A free-boundary, axisymmetric magnetohydrodynamic (MHD) equilibrium code, pyIPREQ, has been developed for Tokamak plasmas using finite difference and Green's function approach. The…
Stabilization of sawteeth instability by short gas pulse injection in ADITYA-U tokamak
Suman Dolui, Kaushlender Singh, Bharat Hegde +28
Experiments on ADITYA-U tokamak show a marked enhancement in the sawtooth period by application of short gas puffs of fuel that cause a modification of the radial density profile.…
Favorable modifications of Scrape-Off Layer (SOL) heat flux width through pulsed fuelling in ADITYA-U Tokamak
SK Injamul Hoque, Harshita Raj, Ritu Dey +19
Enhancement of the scrape-off layer (SOL) heat flux width has been observed in the ADITYA-U Tokamak following the injection of short fuel gas pulses. A notable reduction in paralle…
A multi-purpose reciprocating probe drive system for studying the effect of gas-puffs on edge plasma dynamics in the ADITYA-U tokamak
Kaushlender Singh, Bharat Hegde, Ashok K. Kumawat +24
This article reports the development of a versatile high-speed reciprocating drive system (HRDS) with interchangeable probe heads to characterize the edge plasma region of ADITYA-U…
