Beta = 1 is the target operating regime. Our best analysis indicates that it should be Beta = to just less than one (blowout control, and other thoughts). Scaling will impact where the balance occurs, and that is part of dialing the knobs on the machine. But in my mind, Beta is somewhat synonimous with Wiffleball.Joseph Chikva wrote:If scaling changes beta should you have infinitely large reactor for achievement beta=1?tomclarke wrote:of course wb7 & wb8 beta << 1. It is all about how scaling changes beta.
When the talk is about 3 m reactor what value beta should have?
As I heard from Dan Tibets and others: beta=1, B=10T, n=10^22 m^-3 for 3m reactor.
Are there possible anything destroying scaling law?
Like TOKAMAK for which nobody really knows its behavior when instead of induced current non-induced current will flow (so called "Advanced TOKAMAK").
As far as the WB8 expected outputs, there is a lot we do not know. One of them being the drive potential of the new E-guns on the machine. We know the B field, and we can estimate size from the graphic (from 1.5 to 2.0) based on the bolt patterns and vendor checks. As I recall one estimate was 5/3 size based on the bolt patterns. I would rather go conservative and under-estimate things, that leaves room for pleasant surprise in this case. So say we run numbers for 1.5 x size, 8 x B field (known), and 20KV E-Guns? We can table higher E-gun KV as well if interested.
