Description
It is currently planned to increase the energy of the CEBAF recirculating linear accelerator to 22GeV by adding two new recirculating arcs that contain multiple new energy passes. These new passes at six different energies must be matched to the existing linac simultaneously, as the beam is continuous (CW), so magnets cannot be ramped. This paper studies propagating several energies in the same beam pipe with a line of quadrupoles acting on all of them simultaneously, with the goal that the combined effect produces a match for each energy. Computer optimisation of the performance this system under various constraints (beamline length, number of energies) is studied.
