Title: Status of the CBETA splitter common magnet design

Abstract

The two common dipole magnets in each of the two CBETA splitter sections serve to direct the beams of 42, 78, 114 and 150 MeV from the linac or FFAG return loop exit into the separate splitter lines for path length adjustment and to direct the beams from the splitter into the linac or FFAG return loop entrance. Here we report the results of design and tracking studies based on the Opera V18R2 software. The choice of the H-magnet design included consideration of using the coil design developed for the internal splitter H-dipoles by Elytt Energy. Considerations of transverse space constraints and the bend angle of about 30 degrees for the 42-MeV beam led to the adoption of a T-shape for the pole. The XYZ magnet dimensions are 34 × 42 × 16 cm. The central field value is 3.6-3.9 kG, but the magnet can operate as high as 4.9 kG, allowing for tests of a beam energy as high as 54 MeV in the S1 splitter line. We include results of tracking studies showing optimal placement of the magnets based on bend angle uniformity for the four beam energies. The project now proceeds to the full engineering design andmore » fabrication to be performed by Elytt Energy.« less
