| Résumé | The ROSEBUD collaboration measured the differential flux of fast neutrons inside a shielding of lead irradiated with a source of Cf-252 using two scintillating bolometers of LiF and Al2O3 at 20 mK. We compare an unfolding method using a three parameter model for the fast component of the neutron flux with a multigroup method in which the energy interval of interest is divided into groups. Some issues regarding the neutron monitoring with LiF or Al2O3 in a cryogenic experiment searching for dark matter WIMPs are discussed. |
