Unstable drift-kinetic Alfvén modes with helicity close to the rotational transform
An important feature of some modern facilities (such as optimized stellarators) with low shear is that the value of their rotational transform is close to a rational number. If a mode helicity is close to the rotational transform of the background magnetic field, the Alfvén continuum frequency can lie in the range of the diamagnetic frequencies of the background electrons. An analytical analysi...
متن کاملRotational stabilization of resistive wall modes by the shear alfvén resonance.
It is found that resistive wall modes with a toroidal number n = 1 in tokamaks can be stabilized by plasma rotation at a low Mach number, with the rotation frequency being lower than the ion bounce frequency but larger than the ion and electron precession drift frequencies. The stabilization is the result of the shear-Alfvén resonance, since the thermal resonance effect is negligible in this ro...
متن کاملAlpha-effect dynamos with zero kinetic helicity.
A simple explicit example of a Roberts-type dynamo is given in which the alpha effect of mean-field electrodynamics exists in spite of pointwise vanishing kinetic helicity of the fluid flow. In this way, it is shown that alpha-effect dynamos do not necessarily require nonzero kinetic helicity. A mean-field theory of Roberts-type dynamos is established within the framework of the second-order co...

متن کاملVlasov simulation of kinetic shear Alfvén waves
The treatment of kinetic shear Alfvén waves in homogeneous magnetized plasmas by means of Vlasov simulation is examined. To this end, the driftkinetic version of the Vlasov–Maxwell equations is solved via various numerical schemes, all employing a grid in (1 + 1)D phase space. Since kinetic shear Alfvén waves are Landau damped, the use of an equidistant grid in velocity space leads to a recurre...
