S. Cluzeau et P. Letourneur, STATIONARY DIANE EQUIPMENT - DESCRIPTION AND PERFORMANCE OF THE THERMAL-NEUTRON SOURCE, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 89(1-4), 1994, pp. 428-431
A new neutron radiography facility using a GENIE 46 generator is now o
perating at SODERN (France). In contrast to the first mobile DIANE sys
tem working at IABG (Germany), this new version uses a stationary ther
mal neutron source. With this second equipment the performance has bee
n significantly improved. Thanks to computer simulations and experimen
tal thermal neutron cartography, progress has been made on neutron mod
eration/thermalization (combination of lead and HD polyethylene), extr
action geometry, neutron and photon collimation. The results in terms
of gamma ray and thermal neutron contents in the beam are reported.
