Bonner Balls are used to determine the energy spectrum of a neutron beam. The methodology, which was described in 1960 by Bramblett, Ewing and Bonner of Rice University, uses thermal neutron detectors inserted in the center of polyethylene moderate balls of various sizes. From the comparison of the neutrons detected by each sphere, it is possible to accurately determine neutron energy.
Because of the complexity with which neutrons interact with the environment, precise determination of neutron energy is quite difficult. Bonner Spherical Spectroscopy (BSS) is one of the few methods that provide an accurate neutron spectrum measurement.
A single Bonner sphere of appropriate size can be used for dosimetric determinations using sensitivity sensors approximate to the neutron energy that you want to measure. These Bonner spheres are sometimes known as remballs. Notemodify wikitesto Bibliografiamodifica wikitesto
