Pulsed Wire Measurements of a 120-Pole Superconductive Undulator
摘要
Abstract
The authors consider a way of measuring the magnetic fields of undulators based on wires with a pulsed current. The technique is promising for creating fine-tuning systems for undulators that can work in real time because a single measurement takes only several seconds. Measurements of a pulsed wire field are made using a superconductive 128-pole undulator with a magnetic field amplitude of 1.15 T and a magnetic period of 15.6 mm.
