Document Type and Number:
WIPO Patent Application WO/2015/122526
Kind Code:
A1
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 (1) having a roll contact surface (2) and a free surface (3). The core for a high-frequency acceleration cavity is characterized in that projections (5) having a crater-form depression are dispersed on the free surface (3) of the Fe-based nanocrystal alloy thin strip (1), and the apexes of the projections (5) are ground and blunted.
