MOBP02 FAIR at GSI ion, antiproton, storage-ring, synchrotron 24

  A new faciliy for antiproton and ion research (FAIR) is being planned and prepared to be built at GSI, Germany. R&D and prototype design is presently conducted at GSI and several other institutes worldwide, representing the future FAIR member states. Furthermore a major upgrade program for the running GSI accelerators, the heavy ion linac UNILAC and the heavy ion synchrotron SIS18 has been started. In parallel, the plannings for buildings and tunnels and the permit procedure for construction were launched. The new facility will consist of a two stage heavy ion synchrotron SIS100/300 for the generation of intense heavy ion and proton beams. These beams can be delivered wether as short compressed bunches for the production of secondary beams with subsequent processing in storage rings or as slow extracted beams with high duty cycle for fixed target experiments. The quality and intensity of the produced secondary beams (rare isotope and antiproton beams) will be significantly improved in a number of storage rings used for stacking, beam cooling and for internal target experiments.  
 
MOBP03 Upgrade of BNL Accelerator Facility luminosity, ion, electron, proton 29

  A number of upgrades are planned for the Brookhaven accelerator facility that is primarily made of RHIC and its injector, the AGS. The RHIC luminosity and proton polarization are to evolve towards the Enhanced Design parameters by 2008. A new Electron Beam Ion Source is under development, and commissioning is expected in 2009. The aim of the RHIC II upgrade is to increase the heavy ion luminosity by an order of magnitude, through electron cooling in store. With the addition of an electron ring, the high-luminosity electron-ion collider proposal eRHIC can be realized. Studies have also been done for a new injector to the AGS replacing the present Booster for an upgrade of the beam average power to 1 MW at 28 GeV. The new injector to match the AGS repetition rate can be either a 1.5-GeV SCL or a FFAG accelerator. With the upgrade of the injector complex, neutrino superbeams could be produced.

  The proposed design of the Rare Isotope Accelerator (RIA) driver linac is based on cw fully superconducting 1.4 GV linac capable to accelerate uranium ions up to 400 MeV/u and protons to 1 GeV with 400 kW beam power. Extensive research and development effort has resolved many technical issues related to the construction of the driver linac and other systems of the RIA facility. Particularly, newly developed high-performance SC cavities will provide the required voltage for the driver linac using 300 cavities designed for six different geometrical betas. We are currently looking at alternatives for staging the facility to reduce the initial cost by about a factor of two. A possibility for the first stage includes ~850 MV driver linac to deliver uranium beams at 200 MeV/u and protons at 550 MeV. Thanks to successful tests of the front end systems, 400 kW beams can be obtained with increased intensities of heavy-ion beams from the ECR and higher rf power in the linac even at the first stage of the facility.
