Abstract
This core for a high-frequency acceleration cavity has shape formed with the single roll process by winding, with an interposed insulating layer, a Fe-based nanocrystal alloy thin strip having a roll contact surface and a free surface. The core for a high-frequency acceleration cavity is characterized in that projections having a crater-form depression are dispersed on the free surface of the Fe-based nanocrystal alloy thin strip, and the apexes of the projections are ground and blunted.
