A 4.7 Tesla metre solenoid for a partial Siberian Snake

We describe the engineering design of a 4.7 T-m solenoid magnet which will be installed at the Brookhaven National Laboratory AGS for a partial Siberian Snake Experiment which is an interlaboratory collaboration. The magnet has an overall length of 2.5 m, a clear bore of 15 cm and operates at a peak field of 2 T. It is pulsed at 4 second intervals with a peak current of 9500 A dc driven from a 150 V power supply. The construction uses conventional hollow copper coils but the return flux yokes are made from 1/8 inch plates bolted together. On assembly the flux yokes and endplates are clamped tightly to the coil to prevent any movement during the current pulse. The fabrication experience and test data will be presented. The magnet was installed in the summer of 1993
