Abstract

The EGYPTOR tokamak is a small device of rectangular cross section 25 × 20 cm. Its major (R) and minor (A) radius are 30 and 10 cm, respectively. The aspect ratio is 3. The present work is devoted to measure the absolute values of the discharge currents and to calibrate the different power systems used to supply different coils in the tokamak. Two different methods are applied to measure the discharge currents from different capacitor banks. The first is the direct method employing a calibrated resistance R=0.008 Ω; this resistance was prepared and calibrated in the IPP of the Czech Academy of Sciences, Czech Republic. The second is the indirect method using a calibrated Rogowski coil, fabricated and calibrated also in Prague (Czech Rogowski coil). Both methods are applied simultaneously. Details of each power system presently used are reported. Sensitivity calibration of two different Rogowski coils is also done, and comparison with the calculated sensitivity shows good agreement.
