Best Designs - Linac900Ext6tc2

The revisiting of a past simulation looks to improve on what was a fairly mediocre design, with a bit more time, and a 'twist'.

The best design was 4.387044% by a Boinc Wrapper user (there is no way to tell who it is)

There was some concern over the RF field used. 'd2' lattices had been rather lacklustre in the past, and l900r6c2 had been one of the best results. Do adding the Ext touch, and letting it have a longer maximum simulation time (from 2µs to 3.5µ, hence the t in the lattice name) gives us the lattice.

It has been the best performing lattice since the move to the high target energy range with Linac88Mhz900MeV1, and only the 7th one to break 4% overall.

The search space is in the 10237 range with 79 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 1 hour, 33 minutes 50 seconds.
