Abstract

The main goal of this study is to clarify the possibility to obtain the plasma discharge and to prolong its duration as much as possible, and to analyze what are the preventing reasons of obtaining this goal. Possible reasons can be improper operation of the power supply system, a high level of stray magnetic fields, lack of equilibrium, influence of MHD instabilities, and a high level of impurities. We analyze experimentally these possibilities and discuss them in more details.

Highlights

  • Introduction and Experimental FacilityThe Egyptian facility is a small device of rectangular cross section 25 × 20 cm

  • That is why first of all we checked the operation of the ohmic heating power supply system

  • It critically depends on the normal operation of a Vacuum Interrupter (VI) in the circuit of the so-called OH “slow” battery [1]

Study of Possible Obstacles Preventing Obtaining a Tokomak Regime in the Egyptian Machine. The main goal of this study is to clarify the possibility to obtain the plasma discharge and to prolong its duration as much as possible, and to analyze what are the preventing reasons of obtaining this goal. Possible reasons can be improper operation of the power supply system, a high level of stray magnetic fields, lack of equilibrium, influence of MHD instabilities, and a high level of impurities.
