A 14-MeV intense neutron source based on muon-catalyzed fusion - III: Thermohydraulic regime of the synthesizer

Design calculations of thermohydraulic parameters of the secondary target o f the intense neutron source (INS) based on muon-catalyzed fusion (mu CF) ( the mu CF-INS) are presented for a liquid deuterium-tritium (D-T) mixture. The synthesizer is connected to an external cooler by input and output pipe lines. The optimal mixture composition, synthesizer layout, and dimensions ave determined The possibility of creating a D-T mixture flow with a quasi- uniform velocity distribution is demonstrated. Possible vortexes were found to be eliminated by installation of corresponding hydraulic resistance in the shape of a spherical shell segment. At the mu CF-INS operation with its design parameters [neutron flux as high as 10(14)n/(cm(2).s)], the total h eat deposit in the D-T mixture due to fusion and charged-particle ionizatio n losses is estimated at similar to 117 kW. However, even at such condition s, with the appropriate synthesizer geometry and mass flow rate, the mixtur e temperature does not exceed the boiling point in any part of the synthesi zer.
