A Pion Generator for Medical Irradiation (PIGMI) possessing many technical innovations is being developed at the Los Alamos Scientific Laboratory. The heart of the PIGMI facility is a linear accelerator designed to provide a 650-MeV beam of protons at a beam current of 100 ..mu..A. The accelerator will be 120 m long and suitable for installation at major hospital sites. Obviously, a shorter machine may be more convenient to the medical profession. One possibility of reducing the total length of the facility is to bend the linac back on itself at the halfway point. However, the 180/sup 0/ bending system used for this purpose must have the very special properties of being both achromatic and isochronous in order to transport the proton beam without destroying the transverse or longitudinal dimensions of the bunch. The design of two such possible systems is dicussed.
