Description
Summary:A steady‐state source of electrons was installed in the Compact Auburn Torsatron (CAT) [Fusion Technol. 18, 28 (1990)]. The transport of the electrons was studied with externally applied resonant magnetic fields. Magnetic fields with primary modes n/m=1/4 and n/m=1/3, and average radial field amplitude 〈(b r /B φ)rms〉∼1% have been employed. The perturbation fields produced mixed islands and stochastic regions at the outer region of the CAT torsatron. The particle diffusion coefficient was measured and compared to stochastic transport models.
