Electron Bernstein Wave Research on CDX-U and NSTX
Mode-converted electron Bernstein waves (EBWs) potentially allow the measurement of local electron temperature (Te) and the implementation of local heating and current drive in spherical torus (ST) devices, which are not directly accessible to low harmonic electron cyclotron waves. This paper reports on the measurement of X-mode radiation mode-converted from EBWs observed normal to the magnetic...

tions of the channels. The p4 squarate has C,, crystallographic symmetry, whereas the pJp, squarate and vanadium dimer have D,, symmetry. The window of the square channels has dimensions p a l 2 x c = 7.04 x 7.11 A, which is comparable to the pore size of SAPO-40 zeolite (6.7 x 6.9 The water cluster in the ab plane is further hydrogen-bonded into a layer, resulting in additional eight-membered ...
متن کاملNatural velocity of magnetic islands.
The phase velocity of magnetic islands is calculated in the semicollisional regime with cold ions. Two solution branches arise, corresponding to islands propagating with the ions and with the electrons. For the ion branch the phase velocity and the polarization current are small. For the electron branch, the phase velocity depends on the ratio of W, the half-width of the island, and rho(s), the...
متن کاملTopological Classification of Multiaxial U(n)-Actions
Since early 1980s, great progress has been made on the classification of finite group actions on the sphere. Deep but indirect connections to representation theory were discovered. The indirectness is reflected by the existence of non-linear similarities between some linearly inequivalent representations [3], via the equivariant signature operator [MR] (see also [HP??] [4]). Whitehead torsion, ...
