Response of a magnetically diverted tokamak plasma to a resonant magnetic perturbation
R. Fitzpatrick
The safety-factor profile of a magnetically diverted tokamak plasma diverges logarithmically as the magnetic separatrix (a.k.a. the last closed magnetic flux-surface) is approached…
A Simple Model of Current Ramp-Up and Ramp-Down in Tokamaks
R. Fitzpatrick
A simple model of the ramp-up and ramp-down of the toroidal current in a tokamak plasma is developed. Faraday's law of electric induction is found to limit how rapidly the current…
Investigation of Neoclassical Tearing Mode Detection by ECE Radiometry in Tokamak Reactors via Asymptotic Matching Techniques
R. Fitzpatrick
The TJ toroidal tearing mode code is used to make realistic predictions of the electron cyclotron emission (ECE) signals generated by neoclassical tearing modes (NTMs) in an ITER-l…
Investigation of Tearing Mode Stability Near Ideal Stability Boundaries Via Asymptotic Matching Techniques
Richard Fitzpatrick
A number of improvements to the TJ toroidal tearing mode code [Phys. Plasmas 31, 102507 (2024)] are documented. The TJ code is also successfully benchmarked against the STRIDE toro…
