A small size spectrometer for detecting heavy reaction products emitte
d at small angles has been developed. It is installed at the synchrotr
on storage ring CELSIUS in Uppsala. It uses the focussing and bending
magnetic elements of the storage ring itself in combination with a det
ector telescope, made of high-purity germanium, inserted into the ring
vacuum. The spectrometer has been used for studies of pion production
reactions close to threshold. The spectrometer is described together
with results of ray-trace calculations and experimental tests.
