Presentation Transcript

  1. HISPEC/DESPEC FAIR (Facility for Antiproton and Ion Research) (Darmstadt, Germany) 350m ~1GeV/u fragmentation/fission fragment separator PANDA R3B low-energy cave 0-200 MeV/u HISPEC, DESPEC, LASPEC Zsolt Podolyák ring branch EXL, ILIMA

  2. Production yields and physics at FAIR: High primary beam intensity ~1012 ion/s for 238U High transmission (SuperFRS)

  3. Comparison of FRS and Super-FRS -increase in transmission for fission products (a factor of 10) -cleaner beams due to the higher number of stages H. Geissel et al. NIM B 204 (2003) 71

  4. CDR p.65. Some physics questions with radioactive beam

  5. N=82 N=126 Larger differences (lack of experimental data) H. Grawe, K. Langanke, G. Martinez-Pinedo, to be published.

  6. Features • isotopes of all elements; 0 MeV/u < E <200 MeV/u • ions with short lifetimes (>100 ns) • beam cocktail or mono isotopic beams • isomeric beams • -gamma-ray spectroscopy + + • - particle spectroscopy + + • intermediate energy beams: 50-100 MeV/u • Coulomb barrier beams • decay spectroscopy HISPEC/DESPEC

  7. High-resolution In-flight SPECtroscopy (HISPEC) Particle tracking (Z,pos.,E) Identification (spectrometer, LYCCA) Charged particle det., plunger γ-ray det.
