Spectrum unfolding is a key tool used together with diagnostics in the determination of nuclear fields that are associated with a range of nuclear technologies spanning fusion, fission, nuclear medicine and accelerator domains. The underlying process requires a mathematical method for solving the Fredholm integral equation of the first kind. This p…

We discuss the development, testing and comparison of a combined framework of methods for per-forming neutron spectrum unfolding, which includes the UF_G and UF_M codes, based on the un-derlying mathematics of the GRAVEL and MAXED methods respectively, along with a custom pa-rameterised code, UF_P. We compared the behaviour of each method using a s…


This paper reports new activities conducted as part of the JET technology programme under the WP-JET3 ACT sub-project collaboration. The aim of the sub-project is to take advantage of the significant 14 MeV neutron fluence expected during JET operations to irradiate samples of materials that will used in the manufacturing of main ITER tokamak compo…
