O096800100005 AUTHOR (F.Flesch, S.E.Hirzebruch, G.Huentrup, H.Rocher, O096800100006 T.Streibel, E.Winkel, W.Heinrich) O096800100007 INSTITUTE (2GERGER) University of Siegen O096800100008 REFERENCE (J,RM,31,533,1999) O096800100009 HISTORY (20020604C) O096800100010 (20030512U) Last checking has been done. O096800100011 SAMPLE The target had a thickness of 20% of the interaction O096800100012 mean free path of the beam particles. This value was O096800100013 found to be a good compromise to maximize the number O096800100014 of projectile fragments produced inside the target O096800100015 without generating too many reinteractions of these O096800100016 fragments inside the target. O096800100017 ANALYSIS Track positions on CR-39 foils as well as the track O096800100018 area and shape of the each figures were determined by O096800100019 completely automated measurements.They were performed O096800100020 with scanning system based on computer controlled O096800100021 microscope stage and image analysis techniques. O096800100022 DETECTOR (TRD) CR-39 plastic nuclear track detectors- O096800100023 C-12/H-18/O-7. In experiments was used stacks with 3 toO096800100024 detector foils upstream and 9 to 12 detector foils O096800100025 downstream a target. Each detector foil had a thicknessO096800100026 of about 640-mum. O096800100027 COMMENT -By authors. The cross sections are derived from the O096800100028 number of particles with different charges counted up- O096800100029 and down-stream the target. Since one has to count the O096800100030 number of fragments produced inside the target by the O096800100031 interaction of a well defined number of incoming O096800100032 particles,the number of projictiles and fragments has O096800100033 to be counter in congruent areas. Between 80% and 90% O096800100034 of all tracks could be reconstructed through the thick O096800100035 targets. Some of these tracks were used to determine O096800100036 the congruent areas on the last foil side in the front O096800100037 and the first foil side in the back stack.
