Abstract
It is shown that a cw electromagnetic wiggler can be constructed from chilled high-purity copper that is capable of delivering higher magnet ic field strengths and vector potential, a(w), than either permanent m agnet or superconducting wigglers. A model calculation with a 90 MeV b eam lasing at 1.7 mum showed a 20% higher a(w) than a superconducting system, giving a 23% shorter wiggler period and 16% higher efficiency. Experimental measurements of magnetoresistive effects in copper are i ncluded in this paper.
