  The baseline design for the ESS-B accelerator adheres to suggestions made by ESS-I, and seeks to enter a design phase for a machine based upon a 150 mA +H proton beam. Such intensity was to be delivered, as stated in the 2003 Technical Report by a tandem of two proton ion sources of some 85 mA each funnelled after the two beams are accelerated up to about 20 MeV. Current activities developed during the last few years within the CARE and EUROTRANS efforts have resulted in significant advances in both ion source and low-energy acceleration technologies which will surely have a relevant impact on the proposed accelerator design. More into specifics, our current activities are being directed towards the exploration of:
  1. The use of a single proton source capable to deliver proton currents of 150 mA or above. Proton sources such as SILHI at CEA have already produced currents of 130 mA at low duty factors.
  2. The use of superconducting cavities (spokes, quarter-wave etc.) for medium energy (40 - 100 MeV) acceleration (IFMIF and SPIRAL2).
  3. The behaviour of beams extracted from present day proton ECR sources at medium and high energies.

  High power proton accelerators (HPPAs) with beam powers in the several megawatt range have many applications including drivers for spallation neutron sources, neutrino factories, waste transmuters and tritium production facilities. The UK's commitment to the development of the next generation of HPPAs is demonstrated by a test stand being constructed in collaboration between RAL, Imperial College London, the University of Warwick and the Universidad del Pais Vasco, Bilbao. The aim of the RAL Front End Test Stand is to demonstrate that chopped low energy beams of high quality can be produced and is intended to allow generic experiments exploring a variety of operational conditions. This paper describes the current status of the RAL Front End Test Stand.
