The radial electric field is calculated from the radial component of the force balance equation. It has been shown that three major driving forces have contributed radial electric field including radial pressure gradient, poloidal and toroidal rotation. In this study, we have considered the contribution of these terms, thereby calculating the profiles of plasma parameters by using fluids equations...
The magnetic field of a set of saddle coils compared to the magnetic field of the helical winding coil on IR-T1 tokamak in a simulation method. The equation of helical windings that they mounted on vacuum chamber in a spiral modes (L=2, n=1) and (L=3, n=1), where L represents the number of toroidal rounds, and n represents the direction of the poloidal round, using Green function has been calculated,...
A suitable instrument for electron temperature measurement in Tokamak is electron cyclotron emission diagnostic. We used a heterodyne radiometer in Iran-Tokamak-1 (IR-T1) to measure this parameter. This 5 channel system works in Kα-band and has a very fast response time and good resolution frequency for IR-T1 tokamak. This receiver was used outside the Tokamak, perpendicular to Bt, and with second...
A method for the measurement of the plasma position in the IR-T1 tokamak in toroidal coordinates is developed. A sine-coil, which is a Rogowski coil with a variable wiring density is designed and fabricated for this purpose. An array of Mirnov coils employed for measurement of plasma position. An analytic solution of the Biot-Savart law, which is used to calculate magnetic fields created by toroidal...
