Best Designs - Linac900Ext9X

So, after 10 months, and 44 entries, the 'Best Designs' series comes to a temporary close, with Linac900Ext9X. This lattice, the last to be 'finished' brings the series to an end, but will be revisited when more lattices close.

The best design was 2.506735% by TOMAZ


So we finally come to Linac900Ext9X, the lattice that replaced Linac900Ext6X. As has been common with the Ext series, it's about trying to force new discovery paths.

Instead of the 6 blocks of 6X, as the name suggests, it uses 9. While the final yield was not the most impressive, it was terminated when stuck at a much lower value - around 1.76% - and this score came in 3 weeks later, and was not developed further. This may change.

This was the last lattice to be completed at present, so it's the last in this series for a while.

The search space is in the 10³⁰⁹ range with 103 parameters. The lattice showed a two-stage growth pattern.

The X in the lattice name, replaces the t and also indicates extended time, but also marked it as lattice that required v4.45 at minimum.

This is the 'best' design as recreated in v4.45. The original simulation length as recorded was 68 minutes 07 seconds.
