Spectroscopic investigations of divertor detachment in TCV
K. Verhaegh, B. Lipschultz, B. P. Duval +13
The aim of this work is to provide an understanding of detachment at TCV with emphasis on analysis of the Balmer line emission. A new Divertor Spectroscopy System has been develope…
Characterisation of the L-mode Scrape Off Layer in MAST: decay lengths
F. Militello, L. Garzotti, J. Harrison +7
This work presents a detailed characterisation of the MAST Scrape Off Layer in L-mode. Scans in line averaged density, plasma current and toroidal magnetic field were performed. A…
Current understanding of the processes underlying the triggering of and energy loss associated with type I ELMs
A. Kirk, D. Dunai, M. Dunne +7
The type I ELMy H-mode is the baseline operating scenario for ITER. While it is known that the type I ELM ultimately results from the peeling-ballooning instability, there is growi…
Characteristics of X-point Lobe Structures in Single-Null Discharges on MAST
J. R. Harrison, A. Kirk, I. T. Chapman +4
Lobe structures due to the application of resonant magnetic perturbations (RMPs) have been observed using wide-angle imaging of light from He1+ ions in the vicinity of the lower X-…
Scrape-off layer ion temperature measurements at the divertor target in MAST by retarding field energy analyser
S. Elmore, S. Y. Allan, A. Kirk +6
Knowledge of the ion temperature (Ti) is of key importance for determining heat fluxes to the divertor and plasma facing components, however data regarding this is limited compared…
Understanding the effect resonant magnetic perturbations have on ELMs
A. Kirk, I. T. Chapman, T. E. Evans +8
All current estimations of the energy released by type I ELMs indicate that, in order to ensure an adequate lifetime of the divertor targets on ITER, a mechanism is required to dec…
L-Mode and Inter-ELM Divertor Particle and Heat Flux Width Scaling on MAST
J. R. Harrison, G. M. Fishpool, A. Kirk
The distribution of particles and power to plasma-facing components is of key importance in the design of next-generation fusion devices. Power and particle decay lengths have been…
MAST-Upgrade Divertor Facility and Assessing Performance of Long-Legged Divertors
G. Fishpool, J. Canik, G. Cunningham +7
A potentially important feature in a divertor design for a high-power tokamak is an extended and expanded divertor leg. The upgrade to MAST will allow a wide range of such divertor…
Divertor heat fluxes and profiles during mitigated and unmitigated Edge Localised Modes (ELMs) on the Mega Amp Spherical Tokamak (MAST)
A. J. Thornton, A. Kirk, I. T. Chapman +2
Edge localised modes (ELMs) are a concern for future devices as they can limit the operational lifetime of the divertor. The mitigation of ELMs can be performed by the application…
Effect of resonant magnetic perturbations with toroidal mode numbers of 4 and 6 on ELMs in single null H-mode plasmas in MAST
A. Kirk, I. T. Chapman, J. Harrison +6
The application of resonant magnetic perturbations (RMPs) with a toroidal mode number of n=4 or n=6 to lower single null plasmas in the MAST tokamak produces up to a factor of 5 in…
Effect of resonant magnetic perturbations on ELMs in connected double null plasmas in MAST
A. Kirk, Yueqiang Liu, I. T. Chapman +5
The application of resonant magnetic perturbations (RMPs) with a toroidal mode number of n=3 to connected double null plasmas in the MAST tokamak produces up to a factor of 9 incre…
Strike point splitting induced by the application of magnetic perturbations on MAST
P. Cahyna, M. Peterka, A. Kirk +5
Divertor strike point splitting induced by resonant magnetic perturbations (RMPs) has been observed on MAST for a variety of RMP configurations in a plasma scenario with Ip=750kA w…
Observation of lobes near the X-point in resonant magnetic perturbation experiments on MAST
A. Kirk, J. Harrison, Yueqiang Liu +4
The application of non-axisymmetric resonant magnetic perturbations (RMPs) with a toroidal mode number n=6 in the MAST tokamak produces a significant reduction in plasma energy los…
