PERFORMANCE OF THE STRETCHED- AND VIBRATING-WIRE: PERFORMANCE OF THE STRETCHED- AND VIBRATING-WIRE LOCATING QUADRUPOLE MAGNETIC AXES

A systematic comparison of performance of stretched-wire and vibrating-wire methods for measuring the magnetic axis of a reference quadrupole magnet is presented. The compatibility of the two measurements is demonstrated and the precision of the two methods is compared as a function of the magnet gr...

Sumario:A systematic comparison of performance of stretched-wire and vibrating-wire methods for measuring the magnetic axis of a reference quadrupole magnet is presented. The compatibility of the two measurements is demonstrated and the precision of the two methods is compared as a function of the magnet gradient. Furthermore, a correction technique for the influence of non-uniform background fields is proposed for the vibrating-wire method. Experimental results are given for a normal-conducting quadrupole magnet.
