Description

A new linear analysis for magnetic helical instabilities of are discharges in a cylindrical plasma is developed based on a set of electrostatic magnetohydrodynamic equations. The resistive-viscous m =1 'slow' modes with an external axial magnetic field are studied in the correct electrostatic ordering for the perturbed energy equation. All quantities and the growth rates of helical instabilities are obtained analytically. In addition, the effects of the external axial magnetic field, the arc currents and the rates between arc column radius and tube radius, on the arc helical instabilities are discussed
