Magnetized Positive Column in Turbulence

Positive Column in magnetic fields B which are much stronger than the critical field B c for helical instability is studied theoretically. Radial density distributions n 0 ( r ) of charged particles are expressed by the confluent hypergeometric function when the time average is proportional to r n 0 ( r ), where n 1 and E 1 are the fluctuating densities and electric fields. Relative magnitudes of the discharge electric field E 0 z to that at B =0 are estimated through the degree of . From constant fields E 0 z regardless of an increase of B , it is derived that | | almost linearly depends on B and loss flows of the plasma across B become constant.
