Magnetic measurement system for high-field magnets

Abstract

One of the main principles in electrodynamics, the change of magnetic ®eld¯ux inducing an EMF in a wire coil, is applied for magnetic measurement. A scheme and the main parameters of the magnetic measurement system are described. The system was successfully used for magnetic measurement of a 7 T superconducting wiggler for LSU CAMD; results are presented.

Superconducting 7 T wiggler for LSU CAMD

“…After six quenches, a maximum ®eld of 7.2 T was achieved on 16 March 1997. The results of the magnetic ®eld measurement along the wiggler axis are presented by Borovikov et al (1998).…”

Status of the CAMD Light Source

“…With the growth in the Facility's research program over the last several years, and in particular following the commissioning of a 7 T wiggler [2], a demand has arisen for both higher flux density and beam brightness. The flux density was increased by changing the optic to give a significantly reduced vertical beta value [3] at the wiggler source point.…”
