In this project, dubbed CHESS-U, an 80 meter section of the Cornell Electron Storage Ring (CESR) will be replaced by 12 compact double-bend achromats (DBA’s) to lower electron beam emittance by a factor of three. The critical element in the achromat is a 2.3 meter long combined function (CF) dipole magnet which has a curved geometry. In this cost-effective and transversely compact design, the magnet has a “C-shape” core of dimensions 260 x 412 mm and tapered pole shape. This vertically focusing bending magnet will produce a nominal field of 0.651 T and a gradient of 9.365 T/m. This project is currently in the manufacturing phases and is scheduled to have first articles ready for testing by March 2017.
