Abstract
A detector system of the first focal plane of SMART, the 135 MeV/u hig h-resolution spectrometer at RIKEN Accelerator Research Facility, is d escribed. It consists of a pair of multi-wire drift chambers and a tri gger scintillator hodoscope contained in a He-filled detector box. A m ajor subject using this system is the measurement of the (d,He-2) reac tion making the most of its large angular and momentum acceptances. Wi thout seriously sacrificing the detection efficiency, reasonably good energy and angular resolutions for He-2, 460 keV and 9 mrad (FWHM), re spectively, have been achieved after optimizing the optics property of the spectrometer.
