Abstract

An Adiabatic Matching Device (AMD), which generates a tapered magnetic field with initial on-axis field up to 5 Tesla, is required in ILC positron capturing optics. A proposed scheme is to use a pulsed normal conducting flux concentrator to generate the strong magnetic field. By varying the inner shape of a flux concentrator, one can shape the on-axis magnetic field profile of the AMD. In this paper, we present an equivalent circuit model of a pulsed flux concentrator based on frequency domain analysis. We have constructed a prototype flux concentrator based on the circuit model, and experimental results are presented to validate the model. Using the equivalent circuit model, a flux concentrator based AMD is designed for the ILC positron matching. The beam capturing simulation results using the designed AMD are presented in this paper.
