Studies of ferrite materials for the AGS Booster Synchrotron

The BNL (Brookhaven National Laboratory) Booster Synchrotron injects heavy ion and proton beams of increased intensity into the Alternating Gradient Synchrotron (AGS). Its accelerating cavities are sweep-tuned by varying the permeability of ferrite core rings within the cavities. Core material selection criteria and evaluation are discussed. Measurements of permeability, loss, and permittivity are presented.<
