Abstract

The high-resolution SHARAQ spectrometer and the dedicated beam-line have been constructed at the RI beam factory. Cathode-readout drift chambers placed at the focal plane of SHARAQ and multi-wire drift chambers in the beam-line worked satisfactorily for heavy ion beams with Z=1-7 at 200-250 MeV/nucleon. By introducing a dispersion matched operation of the beam-line, we have achieved a momentum resolution of Δp/p = 1/8100 for a primary beam of ¹⁴N beam with a momentum spread of ±0.1%.
