Preaccelerator concepts for an energy-recovering superconducting accelerator

Preaccelerator concepts for an energy-recovering superconducting accelerator

In this paper we compare two concepts of a preaccelerator for the energy-recovery linac MESA: a hybrid injector that combines normal conducting and superconducting technology and a fully normal conducting injector. The particle source delivers polarized electrons at 100 keV. Thus the first accelerat...
