Abstract
A 3.5 Tesla pulsed magnet with a 1.35 meter bore wound with copper strips has been developed, successfully tested and used at GE Global Research. The magnet has energy of 14 MJ at the peak field. The magnet is composed of 4 pancake coils in series pre-cooled with liquid Nitrogen and powered by a 750 V, 8000 A power supply. This paper describes the design of the magnet, power supply, control circuit and the test results of the system
