[en] The preionization is discussed in Alvand IIC tokamak. Various preionization methods have been examined. It was found that the preionization has a strong influence on the formation and equilibrium of Alvand IIC tokamak plasmas. Carelessly handling of it leads to either not formation or delayed formation of plasma and causes a great deal of preliminary energy loss. Although a high frequency induced electric field makes a suitable preionization at high energies but creates noises in controlling and diagnostic systems and spoils their operation. Electron beam injection by means of an electron gun, makes sufficient preionization in high Zeff, if the beam flow direction is chosen correctly, but in low Zeff it fails in not so low beam energies. However, it has found that an arc discharge between two electrodes installed in limiter shadow, creates a suitable preionization if it is arranged correctly. We have used the secondary of a pulse transformer with a very low turns' ratio of secondary to primary to feed the electrodes

[en] A new method for creating high-current plasma channels is developed. The method uses a narrow gas column formed by the leading particles of a nonsteady gas jet outflowing into a vacuum. An electric discharge device with a system for the formation of a narrow gas column is experimentally studied. The parameters of emission from the plasma channel are measured
