Injector design for high-current cw proton linacs

We present an injector design for high-power cw proton linacs with particular emphasis on intense neutron-spallation sources. Long-term operational reliability and availability dominate over specific beam parameters for these accelerators. We discuss technical requirements for the ion source and low-energy beam transport line and compare different options. A prototype design for a 75-kV, 110-mA cw proton injector is presented.<
