Large Potential Change Induced by Pellet Injection in JIPP T-IIU Tokamak Plasmas

, 1995
"A large, rapid change in the local plasma potential is found to be induced by off-axis hydrogen ice-pellet injection into a tokamak plasma. The polarity of the rapid change is reversed when the pellet is injected into the upper and lower halves of the ...

Completely bootstrapped tokamak

, 1991
A fundamental requirement for the successful operation of a tokamak is the maintenance of a toroidal electric current within the tokamak plasma itself. Maintaining this internal plasma current can be a very difficult technological problem.

Spectra of magnetic perturbations triggered by pellets in JET plasmas [PDF]

, 2010
Aiming at investigating edge localised mode (ELM) pacing for future application on ITER, experiments have been conducted on JET injecting pellets in different plasma configurations, including high confinement regimes with type-I and type-III ELMs, low ...

Structure of chaotic magnetic field lines in IR-T1 tokamak due to ergodic magnetic limiter

AIP Advances, 2018
In this paper we have studied an Ergodic Magnetic Limiter (EML) based chaotic magnetic field for transport control in the edge plasma of IR-T1 tokamak. The resonance created by the EML causes perturbation of the equilibrium field line in tokamak and as a

Steady State Tokamak Sustained by Bootstrap Current Without Seed Current

, 1992
Steady state tokamak solution is studied by taking into account the current diffusivity. The seed current for generating the Bootstrap current is supplied through the radial diffusion of the Bootstrap current.
