Best Designs - Linac900NoGaps1

One of the constants is the gaps between segments. It allows fields to be separate. What if the gaps could be reduced, or even eliminated? That's what Linac900NoGaps (as the name suggests) looks to investigate.

The best design was 2.280941% by Team Anandtech's's amd.borg (AGAIN!)

After the rash of design lattices, it was almost 6 months before a new lattice was released. This one was not very popular, partly because of initial seeding allowing it to top-out quickly.

This lattice is, yet again, a refinement lattice, taking Linac88MHz900MeV1 and tweaking it. The initial 10 solenoids in the design can have a zero gap ,which led to some unusual designs

The search space is in the 10³⁶⁰ range with 120 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 41 minutes 28 seconds.
