摘要
SIRIUS-M is a fusion materials test facility designed to duplicate the time-dependent radiation damage structure unique to ICF systems in order to provide the technology base necessary for an ICF demonstration facility. Single-shell ICF targets are symmetrically illuminated by 32 beams of a KrF laser with a total laser energy of 1 MJ. A wall loading of 2 MW/m 2 is achieved at a repetition rate of 10 Hz and target gain of 13.4. Xenon gas at a pressure of 133 Pa (1 torr) is placed in the 2 m radius, graphite-tiled, cavity in order to protect the first wall from the X-rays and ions produced by the explosions. Two circular test modules are used in SIRIUS-M. Each module has a front surface area of 1 m 2 and fits between three beam ports. No significant radial and azimuthal damage variation in the module results from these penetrations. The peak dpa rate is 24 dpa/FPY yielding a peak accumulated damage of 120 dpa at the end of life of the SIRIUS-M facility. A total volume-integrated-damage figure of merit of 2840 dpa-l per full power year can be achieved in SIRIUS-M. © 1986.
