| Abstract |
IFMIF (International Fusion Material Irradiation Facility) will be a Li(d, xn) neutron source providing equivalent neutron spectrum of DT fusion reactions and comparable neutron flux of future commercial reactors. IFMIF, presently in its EVEDA (Engineering Validation and Engineering Design Activities) phase is installing LIPAc (Linear IFMIF Prototype Accelerator) in Rokkasho (Japan), a 125 mA CW 9 MeV deuteron beam as validating prototype of IFMIF accelerators. The MPS of LIPAc manages the interlocks for a fast beam stop during anomalous beam losses or other hazardous situations. High speed processing is essential to achieve MPS goals driven by investment protection principles. Since Bragg's peak depth is dependent of energy, power densities by uncontrolled beam losses can be very damaging at low energies; the MPS principles for LIPAc are validating those for IFMIF. Beam losses may lead to severe damages by excessive thermal stresses, annealing or even burn/melting of materials. Careful studies to set the maximum allowable time for a beam shutdown to prevent undesired scenarios during the accelerator operational life have been undertaken.
