Wild cables and survivability of macroscopic molecular structures in hot tokamak plasmas

Abstract

The evidences for tubular rigid-body structures are found in tokamak plasmas, which are similar to long-living filaments observed in a Z-pinch ([1] Kukushkin, Rantsev-Kartinov, Proc. 26-th EPS conf., http://epsppd.epfl.ch/cross/p2087.htm). These structures are suggested to be a "wild cables" produced by the channelling of EM energy pumped from the external electric circuit and propagated to the plasma core in the form of the high frequency EM waves along hypothetical (carbon) microsolid skeletons [1] which are assembled during electric breakdown. It is shown that such skeletons may be protected from the high-temperature ambient plasma by the TEM waves produced thanks to the presence of microsolid skeletons.
