Characteristics of the KIGAM long-counter for the neutron energy range below 2.5 MeV

Experimental and theoretical study of long counters on the departure of “point” assumption and scattering background influence

“…This kind of detector has being used for over 60 years since proposed by Hanson and McKibben in 1947. Many efforts have been made to improve its performance, like De Pangher and Nichols (Pangher and Nichols, 1966), East (East and Walton, 1969), National Physical Laboratory (NPL) Thomas, 2000, 1998;Tagziria et al, 2001;Roberts et al, 2004), Lacoste (Roberts et al, 2010;Lacoste and Gressier, 2010;Lacoste, 2010), KIGAM (Kim et al, 2012), and Hu (Hu et al, 2014).…”
