µ-TPC: a future standard instrument for low energy neutron field characterization

Congrès Animma 2013 / 23-27 juin 2013, Marseille (France)

​In the framework of associated laboratory to the French standard laboratory LNE, IRSN (French Institute for Radioprotection and Nuclear Safety) develops tools to produce neutron fields but also must develop instruments and methods to characterize the neutron fields. In order to measure energy of neutron fields, with energy ranging from 8 keV to 1 MeV, a new primary standard is being developed at the IRSN. This future standard, μ-TPC (Micro Time Projection Chamber), developed in collaboration with the LPSC (Laboratory of subatomic physics and cosmology), is a gaseous detector of recoil nuclei.
