Response of BP-1 to 197Au heavy ions at 11.3 GeV/nucleon

Abstract BP-1 track detectors were exposed to a 11.3 GeV/nucleon 197 Au beam. BP-1 is found to be very sensitive to relativistic heavy ion beams and offers the possibility for accurate systematic measurement of spallation cross sections. The total charge changing cross section and some elemental cross sections for a carbon target were determined.
