Development of a portable isotropic neutron spectrometer.
A portable neutron spectrometry and dosimetry measurement device is in the process of development, which will be capable of accurate characterisation of neutron fields. The instrument is an amalgamation of two well-known techniques the Bonner-sphere and the surface barrier detector. Recent developments in semiconductor materials have allowed the growth of large-area thin-film based semiconductors upon high density polyethylene substrates, on which this detector is formed. Herein we discuss three plausible detection devices and test their results.
