Abstract
Abstract
The National Physical Laboratory has provided industry and research with neutron fluence and dose standard neutron fields since the 1960’s. Sectors such as civil nuclear power, defence, radiation-protection and fusion generation rely on NPLs facilities to operate safely and ensure traceability back to an internationally recognised UK primary standard. A central part of the capability is the 3.5 MV Van de Graaff accelerator which, using light ions, generates monoenergetic fields of neutrons ranging from a few keV to 19 MeV and intense thermal neutron fields. This accelerator is reaching the end of its operational life and a project to replace it is underway.
