Best Designs - Linac88MHz900MeV6

Just as Linac88MHz900MeV1 took PhaseRotLinac1 onward, so too will Linac88MHz900MeV6 for PhaserotLinac6.

The best design was 2.481781% by Team Anandtech's's amd.borg.

This was the fifth and final release in the January 2008 burst, but also had the most number of simulations performed. As the name implies, instead of the single block-per section of Linac88MHz900MeV1, it has 6.

This lattice is, like it's sister lattice, Linac88MHz900MeV1, a refinement. It is also notable because it's one of the first times you can clearly see the actions of the Phase Rotation in a simulation. I've marked the five distinct groups in this screengrab from the video at around the 3 minute mark.

The search space is in the 10³⁷⁵ range with 125 parameters. The lattice showed a single-stage growth pattern.

This is the 'best' design as recreated in v4.45. The original simulation length as recorded was 39 minutes 55 seconds.
