A High Intensity Proton Linear Accelerator for the German Spallation Neutron Source (SNQ)

A proton linac of 1100 MeV energy and 100 mA peak beam current and 5 to 10% duty cycle is proposed for the German Spallation Neutron Source (SNQ). Low beam loss, excellent stability of the accelerating fields and high rf-power conversion efficiency are the major design aspects. Basic parameters and layout are given.
