Detectors for beam tracking for HISPEC/DESPEC

• First tests of tracking at Coulomb barrier
  energies on the basis of existing detectors
• Feasibility studies begin with the RISING slow
  down campaign.

• ?t 0.1 ns. Rate 106 s-1
• Secondary electron detection (TOF position
  information), Saclay, Rosendorf
• ?t 0.1 ns. ?x,?y 1 mm. Rate 106 s-1
• Silicon strip detectors (?E, Z position) fir
  light ions, Seville.

Detectors for beam tracking for HISPEC/DESPEC

• Simulations with key ions 19B, 55Ni, 100Sn,
  132Sn, 220Rn at energies
• 100 MeV/u (GSI, Surray), 10 MeV/u (GSI,
  Seville), 5 MeV/u (Köln, Seville).
• Groups from Köln and Seville proposed to use
  their tandems for detector tests with defocused
  stable beams.
