JET experimental studies

Study of high temperature pedestals

Specific experiments were made at JET to study high temperature pedestals, in the range Te_ped ~2.5-5 keV. The idea was to see if the ELMs are qualitatively different when resistivity and collisionality are low. The surprising result of the experiment was a new insight on pedestal stability: with low gas fuelling and low recycling conditions (required to achieve high temperature pedestals) an Outer Mode often appears, delaying ELMs. The outer mode had been assumed to be an ideal kink, unstable in the steep gradient region of the pedestal, which would eventually grow into an ELM. We have now found that the outer mode is a fairly stable current ribbon, lasting as much as 1.5 s, located at the top of the pedestal. There are tantalising similarities with the EHO observed in DIII-D. This could provide a new route to ELM-free operation.

Tokamak Design

• TEXT Upgrade: calculations for design of diverted plasma and corresponding divertor coils, mostly based on filament models of the plasma:
  • electromagnetic forces and insulation requirements on coils in steady operation and during disruptions,
  • power supply requirements for plasma position control,
  • effect of iron transformer on plasma stability
  • adapted EFIT code to be used in tokamaks with non-satured iron core.

• USTX: the University Spherical Tokamak Experiment design proposal: all of the above, now with predictive EFIT,
  • additional shape control requirements due to effect of transformer currents on inboard plasma gap.
  • stability analysis with DCON
  • design of field null for efficient startup
