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. O096800100038
