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…
Effect of LH and ECR waves on plasma parameters in ADITYA Upgrade tokamak
S. Aich, S. Dolui, K. Singh +29
The plasma discharges in ADITYA Upgrade Tokamak are produced by means of transformer action, in which Ohmically created plasma is driven by means of a secondary loop voltage. Due t…
PRISM: A MATLAB-Based Application for Structured Probe Data Management and Visualization in Tokamak Diagnostics
Priyanka Verma, Subhojit Bose, Harshita Raj +1
The successful operation of tokamak experiments requires accurate documentation, tracking, and visualization of diagnostic instruments, particularly electrical probes. Traditionall…
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…
