The development and characterization of a mobile monitor for Background Neutrons --WITHDRAWN--

Presented by Mr. George TSATSI
Type: Poster Presentation
Session: Poster2
Track: Track B - Nuclear, Particle and Radiation Physics


The need for a dedicated mobile monitor in the immediate external environment of a particle accelerator containment facility led to this study. Essentially, the science and technology applied to the development, optimization and characterization of this mobile detector capable of monitoring the pseudo-background neutron flux, in the vicinity of an accelerator based neutron source was investigated. The details of the neutron flux and the detector response function were investigated and convoluted together to build a neutron profile for the designated area west of the accelerator facility at Necsa. Data from the external mobile monitor outside containment detection system under development was correlated with the standard detectors within the building. The external mobile monitor was designed, using modeling of the physics processes such as simulations of neutron transportation with respect to the skyshine phenomenon. The detector performance has been evaluated using carefully configured source – detector scenarios. Results shall be presented which reflect the cause and effect nature between neutron production, skyshine and the mobile detector response functions.
