Abstract :
New quadrupole focusing magnets have been designed and are being tested and produced for use with the sidecoupled accelerating structure of the Linac Upgrade at Fermilab. Beam dynamic calculations require 1.84 T-m/m for a 2-cm radius aperture. The choice of a 3 beta lambda /2 bridge coupler limited the longitudinal dimension of the magnet core to 7 cm. The magnet is pulsed at the linac´s 15-Hz repetition rate, which forced the development of new field quality measurement techniques. The studies that were made during the design of the magnet and the evaluation of a prototype are presented.<>
