Abstract
A pair of pulsed quadrupoles spaced 180° apart in the Zero Gradient Synchrotron (ZGS) ring was installed to prevent the depolarization of polarized protons during acceleration in the ZGS. These quadrupoles must produce a 50-G/in gradient over a useful aperture of 2 in vertically and 10 in radially. The pulse must have a 10-¿s rise time and a 2¿-ms flattop. They must be pulsed up to ten times during the 1¿-s ZGS acceleration period. The computer calculations and the mechanical and electrical design and fabrication of the quadrupoles and their power supply will be described.
