Abstract
We have developed a simple one-dimensional scintillating fiber detector (SFD) for momentum tagging high-energy (a few hundred MeV per u) and high-intensity ( ∼ 10 6 particles per second, pps) beams of light ( Z ≤ 10 ) ions in the momentum-dispersive focal plane of a fragment separator. This SFD consists of 60 rows of scintillating fibers that have 2 mm square cross-sections. The detection efficiency is constant for beam intensities between 103 and 106 pps and a position detection efficiency of 100% is achieved by injecting ions obliquely. The position resolution is less than 1 mm (rms). In addition, the SFD is demonstrated to be effective for identifying particles in cocktail beams. These results show that the application of scintillating fibers is found to be one of the most suitable methods to tag the light radioactive ion beams.
