  1. Some facts about the existing GSI facility and the planned FAIR project • A short review of the today used electronics for the synchrotron BPMs at GSI • Idea of one unique „Digital BPM analysis electronics“ for all GSI synchrotrons/storage rings • Parameters of the GSI synchrotrons (now and in the future) and others • European collaboration (FP6 proposal): GSI, CERN, FZJ, TUD and Instrumentation Technologies • First prestudies at GSI – talk of Andreas Galatis 1

  2. 1.5 GeV/u U28+ 1012 /s 34 GeV/u U92+ 109 /s 29 GeV p 1013 /s Superconducting double-synchrotron SIS 100/300 2

  3. Heavy Ion Synchrotron Ion sources High Current Linear Accelerator Therapy Renewed 1999 1990 1975 1 -2 GeV/u FRS + ESR with electron& stochastic cooling 15 MeV/u Multi-beamoperation 1997 3

  4. Gain compared to the existing facility/ • new and special beam properties: • Primary beam intensities: Factor 100 – 1000 • Primary beam energy: Factor 25 • Secondary beam intensities for radioactive ions: up to a factor 10000 • New: cooled antiproton beams up to 15 GeV • Special: intense cooled radioactive ion beams • Efficient parallel operation of several experiments 4

  5. Nuclear Structure and Astrophysics Primary beam: 1.5 GeV/u 1012/s uranium ions /50 ns single pulse (1 Hz) or ‘dc’ Secondary beams: Exotic nuclei 0-1000 MeV/u • Research with Antiprotons Primary beam: 30 GeV 2x1013/pp protons / 50 ns single pulse(0.2 Hz) Secondary beams: Stored antiprotons 100 keV - 15 GeV • Nucleus-Nucleus Collisions at High Energy Primary beam: up to 34 GeV/u 109/s uranium ions Pulse structure on the target: ‘dc’ • Dense Plasma Physics Primary beam: 400-1000 MeV/u >1012/pp uranium ions Pulse structure on the target: 50 ns single pulse • Atomic Physics Primary beam: up to 10 GeV/u 109/s uranium ions 5

  7. Turn-by-turn analysis Scheme of the both BPM electronics used at GSI´s SIS18 and ESR Analysis on ms scale 7

  8. Idea of one unique „Digital BPM analysis electronics“ for all GSI accelerators (and others....) Direct digitization of the signals and following data treatment using math. algorithms Amplififier and attenuator chain with 160 dB dynamics Capacitive Pick-ups for cryogenic and warm sections of the synchrotrons New BPM System Setup Idea: Use of modern digital signal processing electronics using fast 12/14-bit 100-250 MSa/s ADCs, DSPs and FPGAs and a „software“ capable to treat (more than) 1 MB/ms raw data of the BPMs! 8
