Pulsed Power for Future Linear Accelerators

Three types of high-energy collider machines are being studied by physics laboratories and collaborations worldwide. These studies cover linear e+e- colliders, muon colliders and very large circular hadron colliders with centre-of-mass energies of 1TeV and beyond. The difference between these new collider schemes and existing machines is the very large amounts of RF power that has to be generated, and therefore the necessary R&D programmes to make them power efficient, cost effective, reliable and compact. Pulsed power in an accelerator complex is associated with many sub-systems that assure an efficient acceleration and transfer of the particle beam from creation at the source, to its required destination. This paper reviews some of the pulsed klystron-modulator systems that are being proposed for the generation of this RF power in some of these e+e- linear collider schemes.
