Description

In the framework of MUNES project, a new neutron source was developed at the CN electrostatic accelerator of Legnaro National Laboratories. Neutrons are produced thruogh Be(p,n) reaction using a thin foil beryllium target brazed on a copper base. A 5 MeV, 3 microA proton beam is focalized onto the target so as to reach a 500 W/cm^2 power density on beryllium, the same as MUNES high intensity accelerator. A heavy water-graphite moderator is used for neutrons thermalization. Preliminary results show that a 1.2*10^6 s^-1*cm^-2 neutron density can be generated at the extraction window with a uniformity better than 1% over a 25 cm diameter circular area. Neutron spectrum is more than 90% thermal with a very low gamma contamination.
