The RAL front end test stand

A design for a proton driver front end test stand at the Rutherford Appleton Laboratory (RAL) in the UK is presented. The aim is to demonstrate the availability of well chopped H- beams suitable for future high power proton accelerators. Advantage is being taken of existing RAL R&D programmes on H- ion sources and beam choppers, and also of a previous RFQ test stand project at RAL for testing a new preinjector RFQ for the ISIS spallation neutron source
