Abstract

Abstract: GLAST is a small spherical tokamak with an insulating vacuum vessel of pyrex. It has major and minor radii of 20 and 10 cm, respectively. Magnetic measurements play a fundamental role in plasma breakdown and start-up studies. This paper presents the development, fabrication, calibration, and installation of magnetic diagnostics on GLAST III Tokamak. Magnetic diagnostics consist of the flux loops, magnetic field pickup sensors, and Rogowski coil. The signals obtained from various coils are integrated with passive analog integrators. The experimental results obtained from these magnetic diagnostics are presented and discussed.
