Abstract :
This paper reports the design and the evaluation of an high stability current source developed for energizing the C-field magnet of the high field cesium standard experiment, currently in progress at Politecnico di Torino. This source, devoted to C-field uniformity measurements, supplies about 1 kW dc power with a current stability of about 10/sup -7/.<>
