| Abstract: | In this work, neutron measurements were carried out for the interaction of 60 and 67.5 MeV 12C,
57.3 and 65 MeV 13C ions with thick aluminium target by using CR-39
detectors and neutron rem meter. Both the detector systems were irradiated at
different angles viz. 0°, 30°, 60°, 90° with respect to the beam
direction. The normalized track density (tracks cm-2 projectile-1 at 1 m)
in CR-39 detectors was correlated with the normalized dose equivalent values
(µSv projectile-1 at 1 m)
obtained using the neutron rem meter. The track density was found to be more in
case of 13C than 12C. However in all the cases, the track
density per incident projectile was found to decrease as the angle with respect
to beam direction increases, indicating non-isotropic nature of neutron
emission. The ratio between measured dose equivalent in rem meter to the
measured track densities in CR-39 detectors was found to be (2.8±0.2) µSv cm2, which remains constant irrespective of the change in
angle with respect to the beam direction as well as in neutron energy
distribution, indicating a flat dose response of CR-39 detectors. |
