Description
At the proposed future circular hadron collider, FCC-hh, the strong synchrotron radiation emitted inside the cold superconducting magnets represents a significant heat load, which is likely to limit the total beam current. This contribution discusses a new approach, namely synchrotron radiation power levelling: The idea is to adjust the beam energy during a physics store, either continually or in a few discrete steps, while the beam current decreases due to proton burn-off in collision, so as to keep the synchrotron radiation power at or below a certain limiting value. In this way, both peak and integrated luminosity of the FCC-hh are increased, compared with operation at a fixed beam energy, thereby maximising the physics output.
