Zusammenfassung:The high-resolution SHARAQ spectrometer and the dedicated high-resolution beam-line have been constructed at the RI beam factory and commissioned in 2009. Multi-wire drift chambers placed in the beam-line and cathode read-out drift chambers placed at the SHARAQ focal plane worked well for heavy ion beams with Z=1-7 at 200-300 MeV/nucleon. By introducing a dispersion matched operation of the beam-line, we have achieved a momentum resolution of Sp/p=1/8100 for a primary beam of (14)N beam with a momentum spread of plus or minus 0.1%. Experiments by use of novel RI-beam induced charge exchange reactions are planned.
