1. A waveguide for use in a linear accelerator, the waveguide comprising:
multiple cells arranged to receive a beam of charged particles therethrough along a particle path, the waveguide being configured to receive an electromagnetic field from a source of electromagnetic radiation, wherein a plurality of the multiple cells are individually switchable cells, and wherein each individually switchable cell includes a respective switch configured to adjust a supply of electromagnetic radiation to the individually switchable cell; and
a first supply channel and a second supply channel arranged substantially parallel to the particle path, wherein each individually switchable cell is arranged between the first supply channel and second supply channel, and wherein the first supply channel and the second supply channel are each configured to supply the electromagnetic radiation to each individually switchable cell.
