Description

We have been developing a flux concentrator (FC) type positron focusing solenoid for SuperKEKB. Due to a serious damage in the present FC by discharge, we have to limit the operation current to less than half of the specification. It is presumed that the yield strength of the FC head made of OFC was not sufficient against magnetic force under a static magnetic field generated by the bridge coils surrounding the FC. We have manufactured a new FC and applied a work hardening process to the head to increase the yield strength. This paper reports on a status of the new FC and a test bench to evaluate the performance of the FC under the magnetic field of the bridge coils. (author)
