Abstract
Forming poles from sectors of a tube of carbon or a material with similar conductive properties and supporting the poles by bonding an insulating support ring thereto before removing end rings formed at the ends of the tube which temporarily support the poles provides a multipole deflector element of robust structure of high dimensional accuracy and stability in which eddy current and charging effects are avoided. The manufacturing method is much simplified, reduced in cost and increased in reliability, repeatability and yield over manufacturing techniques for known multipole deflectors.
