HiCANS are new neutron sources of a very high interest for the future. However some major technological issues remain; one the biggest one being the development of targets able to sustain the high intensity proton beam during a time long enough to have a smooth operation of the source. We will present the developments made in Saclay on high temperature Berylium targets. Two different targets have been tested with a 3 MeV proton beam during long runs; a small ones design to sustain a power up to 1 kW, and a big one design to sustain a power up to 50 kW. Results of 100 hours operations will be presented.
This work is part of the collaboration within ELENA and LENS on the
development of HiCANS. It has been funded by the "CANS Inflexion" program at the CEA and the "IPHI-Neutron" SESAME project of the Ile de France region.
