The IFMIF linacs are designed to accelerate 125 mA
CW deuteron beams up to 40 MeV. The SILHI source
designed to produce such CW high intensity protons or deuterons beams has been recently tested for the IFMIF project. More than 170 mA of deuteron beam have been extracted. In order to avoid neutron production in the Low Energy Beam Transport line the duty factor had to be kept
below 0.2%. Dangerous neutron production level at the beam stop location was observed in less than 2 hours. Beam characteristics and neutron production in the LEBT are reported.
