Edge temperature gradient as intrinsic rotation drive in Alcator C-Mod tokamak plasmas.
نویسندگان
چکیده
Intrinsic rotation has been observed in I-mode plasmas from the C-Mod tokamak, and is found to be similar to that in H mode, both in its edge origin and in the scaling with global pressure. Since both plasmas have similar edge ∇T, but completely different edge ∇n, it may be concluded that the drive of the intrinsic rotation is the edge ∇T rather than ∇P. Evidence suggests that the connection between gradients and rotation is the residual stress, and a scaling for the rotation from conversion of free energy to macroscopic flow is calculated.

The Edge Temperature Gradient as Intrinsic Rotation Drive in Alcator C-Mod Tokamak Plasmas
Intrinsic core toroidal rotation has been observed in I-mode plasmas from the Alcator C-Mod tokamak, and is found to be very similar to the rotation in H-mode discharges, both in its edge origin, profile shape and in the scaling with global plasma pressure. Since Iand H-mode plasmas have similar pedestal temperature gradients, but completely different edge density profiles, it may be concluded ...
متن کاملDensity sensitivity of intrinsic rotation profiles in ICRF-heated L-mode plasmas
The physical mechanisms that cause tokamak plasmas to rotate toroidally without external momentum input are of considerable interest to the plasma physics community. This paper documents a substantial change in both the magnitude of the core rotation frequency, -3 < ω(r/a=0) < +10 kHz, and the sign of rotation shear at mid-radius, u’=-Rdω/dr/vth,i,, which varies between -0.6 < u’ < +0.8 in resp...

متن کاملShear flows at the tokamak edge and their role in core rotation and the L-H transition.
Pfirsch-Schlüter fluxes in tokamaks are shown to drive strong poloidal and toroidal shear flows that are localized to the edge and scrape-off layer in the presence of temperature gradients and finite bootstrap current in the pedestal. Within a magnetohydrodynamic model, the effect of these flows on core rotation and their role in the magnetic configuration dependence of the power threshold for ...
متن کاملH Mode Confinement in Alcator C-mod
A series of experiments, examining the confinement properties of ion cyclotron range of frequencies (ICRF) heated H mode plasmas, has been carried out on the Alcator C-Mod tokamak. Alcator C-Mod is a compact tokamak that operates at high particle, power and current densities at toroidal fields up to 8 T. Under these conditions the plasma is essentially thermal with very little contribution to t...
