Run D is designed to measure the yields of antinuclei produced in these
collisions and to search for negative strangelets.
The magnet will be set to -0.75 T so as to have a good acceptance for
the 
, 
, 
systems. This run is also
sensitive to 
composite.
Since the range of Z/A we wish to cover in this run is larger than for the positive
strangelet runs ( from 0.1 to 0.67 for this run), the acceptance for some species
is less. As seen in Table 
the acceptance times efficiency
for drops to 3.4%. For negative strangelets the acceptance
remains comparable to that for positive strangelets.
We note however that the total flux of particles through the
apparatus is less in the negative running so that we believe we can increase
the interaction rate by up to a factor of three. This would give a sensitivity
for the negative strangelet search of 
of all interactions
and for antinuclei of 
of all interactions (90% confidence
level).
