Observation of confined current ribbon in JET plasmas (2009)

Solano, E. R., Lomas, P. J., Alper, B., Xu, G. S., Andrew, Y., Arnoux, G., ...

we report the identification of a localised current structure inside the JET plasma. It is a field aligned closed helical ribbon, carrying current in the same direction as the background current...

INTERNATIONAL ATOMIC ENERGY AGENCY 1 (2008)

J. R. Drake, P. R. Brunsell, D. Yadikin, H. Bergsåker, M. Cecconello, A. Hedqvist, ...

Experiments on feedback control of multiple resistive wall modes comparing different active coil arrays and sensor types

Active control of type-I edge-localized modes with n=1 perturbation fields in the JET tokamak (2007)

Liang, Y., Koslowski, H. R., Thomas, P. R., Nardon, E., Alper, B., Andrew, P., ...

Type-I edge-localized modes (ELMs) have been mitigated at the JET tokamak using a static external n=1 perturbation field generated by four error field correction coils located far from the plasma....

Active control of type-I edge localized modes on JET (2007)

Liang, Y., Koslowski, H. R., Thomas, P. R., Nardon, E., Jachmich, S., Alper, B., ...

The operational domain for active control of type-I edge localized modes (ELMs) with an n = 1 external magnetic perturbation field induced by the ex-vessel error field correction coils on JET has...

ELMS and strike point jumps (2005)

Solano, E. R., Jachmich, S., Villone, F., Hawkes, N., Corre, Y., Pitts, R. A., ...

If an ELM is a peeling of flux surfaces from the plasma, due to a broken separatrix, current density is lost as well as particles and energy. The fast loss of a current-carrying plasma layer modifies...

Impurity-seeded plasma experiments on JET (2003)

Maddison, G. P., Brix, M., Budny, R., Charlet, M., Coffey, I., Cordey, J. G., ...

Scaling to larger tokamaks of high confinement plasmas with radiating edges, induced by impurities, is being studied through internationally collaborative experiments on JET. In campaigns till the...

Progress towards steady-state operation and real-time control of internal transport barriers in JET (2003)

Litaudon, X., Becoulet, A., Crisanti, F., Wolf, R. C., Baranov, Yu. F., Barbato, E., ...

In JET, advanced tokamak research mainly focuses on plasmas with internal transport barriers (ITBs) that are strongly influenced by the current density profile. A previously developed optimized shear...

Progress towards steady-state operation and real time control of internal transport barriers in JET (2003)

Litaudon, X., Bécoulet, A., Crisanti, F., Wolf, R. C., Baranov, Yu. F., Barbato, E., ...

In JET advanced tokamak research mainly focuses on plasmas with internal transport barriers (ITBs), generated by modifications of the current profile. The formerly developed optimised shear regime...

Equilibria and stability of JET discharges with zero core current density (2003)

Stratton, B. C., Hawkes, N. C., Huysmans, G. T. A., Breslau, J. A., Zakharov, L. E., Alper, B., ...

Injection of Lower Hybrid Heating and Current Drive (LHCD) into the current ramp-up phase of JET discharges has produced extremely reversed q-profiles characterized by a core region of near zero...

Impurity-seeded plasma experiments on JET (2003)

Overview of JET results (2003)

Pamela, J., Solano, E. R., Adams, J. M., Agarici, G., Agarici, M., Akhter, H., ...

Scientific and technical activities on JET focus on the issues likely to affect the ITER design and operation. Our understanding of the ITER reference mode of operation, the ELMy H-mode, has...

The formation and evolution of extreme shear reversal in JET and its influence on local thermal transport (2002)

Hawkes, N. C., Andrew, Y., Challis, C. D., DeAngelis, R., Drozdov, V., Hobirk, J., ...

In JET discharges where lower hybrid heating and current drive (LHCD) is applied early during the current ramp, a region of the plasma with zero current density is formed near the axis. At the...

Extreme shear reversal in JET discharges (2001)

Hawkes, N., Stratton, B., Baranov, Y., Bolzonella, T., Challis, C., Cortes, S., ...
