An experiment to study double-strangeness systems was performed at the
BNL-AGS via the (K-, K+) reaction using a diamond target and scintill
ating fiber (SCIFI) blocks (E885). A search for the H dibaryon through
the stopped Xi(-) process is one of the objectives. The number of sto
pped Xi(-)'s is about 9,000, and the expected sensitivity of the H dib
aryon search is more than one order of magnitude higher than that of t
he previous experiment at KEK-PS (E224).
