M. Luszikbhadra et E. Dietz, REACTOR BEAM PROFILE MEASUREMENTS WITH ELECTROCHEMICALLY ETCHED TRACKDETECTORS, Nuclear tracks & radiation measurements, 22(1-4), 1993, pp. 669-670
The beam profile of the bismuth-filtered thermal neutron beam of the P
TB research reactor has been measured using CR-39 track detectors elec
trochemically etched on a relatively large area of 5.5 x 6.5 cm2. The
tracks were automatically counted with an image analysing system. With
the use of different converters it was possible to determine the loca
l distribution of the thermal neutrons and that of fast neutrons prese
nt in the beam.
