Finemet versus ferrite -- Pros and cons

PDF Version Also Available for Download.

Description

There is a new magnetic alloy called Finemet which has very constant {mu}'{sub p}Qf up to {approximately} 2 kG and is very stable at high magnet flux density and temperature. It may be a good can-didate for high-gradient rf cavities. However, it has a rather low quality factor and is therefore very lossy. We compare the pros and cons of Finemet versus the common ferrite, when used in low-energy accelerating cavities, insertion for space-charge compensation, and barrier cavities.
