Abstract

A precision long counter, based on the design of De Pangher and Nichols, and usually referred to as a De Pangher long counter, has been assembled and characterised for neutron fluence measurements at the Joint Research Centre Geel laboratory. The instrument is based on a De Pangher long counter body that was available at NPL and a new BF3 counting tube. Efficiency and effective centre values for the instrument are presented, as a function of neutron energy, with details of the measurements and calculations that underpin these parameters that are required when deriving the neutron fluence from the counts produced by the instrument.
