Best Designs - Linac900Ext9d2

As with last weeks 6d2 lattice, we're working on a series of blocks, and phases. Now 9 blocks and the d2 RF phase setup.

The best design was 0.789847% by a Boinc Wrapper user (there is no way to tell who it is)

In this, the second of the Ext sequence of lattices (the current generation), the complexity level has been increased from 6 blocks to 9. Running concurrent simulations like this helps to prevent only one design path from being looked at as a whole. A true optimum design would result in a similar design in all such tests, since they have a common design theme.

It is, in many ways, an alternate form of rechecking.

The search space is in the 10³⁶³ range with 121 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 24 minutes 13 seconds.
