O097100100003 AUTHOR (F.Flesch, G.Lancu, W.Heinrich, H.Yasuda) O097100100004 INSTITUTE (2GERGER) University of Siegen O097100100005 (2JPNIRS) National institute of radiological sciences. O097100100006 REFERENCE (J,RM,34,237,2001) O097100100007 REL-REF (R,O0968001,F.FLESCH+,J,RM,31,533,1999) Details of O097100100008 experiments. O097100100009 HISTORY (20020607C) O097100100010 (20030512U) Last checking has been done. O097100100011 SAMPLE A set of nine stacks containing the following targets- O097100100012 polyethylene, Al, Cu, Ag and Pb. The target had a O097100100013 thickness of about 10% of the interaction mean free O097100100014 path of the beam particles. This value was found to beO097100100015 a good compromise to maximize the number of projectile O097100100016 fragments produced inside the target without generatingO097100100017 too many reinteractions of these fragments inside theO097100100018 target. O097100100019 ANALYSIS Track positions on CR-39 foils as well as their track O097100100020 area and shape of the etch figures were determined by O097100100021 completely automated measurements. They were performed O097100100022 with scanning system based on computer controlled O097100100023 microscope stage and image analysis techniques. O097100100024 The cross sections are derived from the number of O097100100025 particles with different charges counted up- and O097100100026 down-stream the target. Since one has to count the O097100100027 number of fragments produced inside the target by the O097100100028 interaction of a well defined number of incoming O097100100029 particles, the number of projictiles and fragments has O097100100030 to be counter in congruent areas. Between 80% and 90% O097100100031 of all tracks could be reconstructed through the thick O097100100032 targets. Some of these tracks were used to determine O097100100033 the congruent areas on the last foil side in the front O097100100034 and the first foil side in the back stack. O097100100035 DETECTOR (TRD) CR-39 plastic nuclear track detectors- O097100100036 in experiments was used stacks with 5 detector foils O097100100037 upstream and 12 detector foils downstream a target. O097100100038 Each detector foil had a thickness of about O097100100039 640-micrometers. By using stacks of Cr-39 foils, it is O097100100040 possible to determine the trajectories and the charges O097100100041 of the projectiles ions and their fragments. O097100100042 The authors get charge resolutions between 0.1 and 0.12O097100100043 elementary gharge for fragments charge numbers from 6 O097100100044 upto 13.
