Collisionless Bulk Electron Heating in Resonant Low-Voltage Capacitively Coupled Plasmas
Sarveshwar Sharma, Igor D. Kaganovich, Animesh Kuley +3
We investigate collisionless power absorption in resonant, lowpressure capacitively coupled plasmas (CCPs). In these radio-frequency (RF) discharges, the sheath capacitance almo…
Magnetohydrodynamic equilibrium and neutronics study on MAST-U using Jenga framework
Saptarshi Rajan Sarkar, Rahul Babu Koneru, Ravi Gupta +4
Tokamak design is inherently challenging due to several cross-competing effects which require a careful and calibrated treatment to obtain an optimal operational envelope. Incorpor…
Design and mechanical analysis of the PRAGYA tokamak vacuum vessel
Ravi Gupta, Rahul Babu Koneru, Saptarshi Rajan Sarkar +4
PRAGYA is India's first privately developed low aspect ratio tokamak designed by Pranos Fusion Energy. The device is designed for a plasma major radius (R0) of about 0.4 m, a plasm…
Gyrokinetic simulation of the effect of transient fueling on plasma turbulence in ADITYA-U tokamak
Jaya Kumar Alageshan, Suman Dolui, Joydeep Ghosh +8
The gradient-driven microturbulence in ADITYA-U tokamak plasmas has been suppressed by injecting short gas puffs. The suppression of microturbulence increases the core temperature…
Effect of static magnetic island on ITG of ADITYA-U tokamak
Vibhor Kumar Singh, Amal R Biju, Jaya Kumar Alageshan +10
Magnetic islands play a crucial role in regulating plasma confinement in tokamaks by interacting with micro-instabilities, such as the ion temperature gradient (ITG) mode. This wor…
Dependence of Core Turbulence and Transport in DIII-D QH-Mode Plasmas
Abhishek Tiwari, Kshitish Barada, Jaya Kumar Alageshan +6
This study investigates the effect of the ion-to-electron temperature ratio () on microturbulence driven transport in Quiescent H-mode (QH-mode) plasmas in the DIII-D toka…
