A fusion relevant neutron source is strongly desired for blanket functional tests and material tests toward DEMO. The International Fusion Material Test Facility (IFMIF) is one of the most promising candidates of the fusion relevant neutron source. Here, a plan is presented for a new neuron source using an IFMIF/EVEDA prototype accelerator with 125 mA and 9 MeV D beam and a lithium test loop for the IFMIF target facility. Expected performances of three options (9 MeV and upgrading to 26 or 40 MeV) are discussed. The option of 40 MeV is desirable, however, the option of 26 MeV is acceptable for blanket functional tests and material tests.
