Third-generation laser uranium enrichment out of Australia, similar to CRISLA, superseding AVLIS and MLIS. The third generation is primarily defined by its end-to-end use of UF6 (uranium hexafluoride). AVLIS used uranium metal; MLIS output UF5.

There are two fundamental insights behind SILEX:

Using hex and a carrier gas G:

  • UF6+G dimers can be broken up and excited with a single photon
  • The mass difference between 235UF6 and a dimer of 238UF6+G is (assuming G is 40Ar), 43, much larger than that between
    • 235U and 238U (3, traditional separation) or
    • 235UF5 and 238UF6 (22, MLIS)
