Abstract

The use of an achromatic bend for a medium energy electron cooling beamline in the new Recycler Ring at Fermilab is required to ensure a stable beam position. This first order 180° achromat consists of two 90° dipoles with a 61 cm bend radius and a central dispersion-suppressing quadrupole flanked symmetrically by a weak solenoid and an air-core cos(2θ) quadrupole. The mechanical design and technique of fabrication for each bend component is discussed. Each of the air cooled mechanical designs are simple yet precise in terms of construction technique. The results of magnetic field measurements are also presented
