Dynamic Axial Field

[RobP]

I’m not sure if the question has been asked before, would there be any benefit in dynamically adjusting the axial field during the shots?

Feedback from the shot itself may even improve the dynamic variation of the field as well, assuming the timings are possible.

Sounds like a good “fuzzy logic” app …

More like using a genetic algorithm to control the change in axial field based on some monitored output, which would then find the ideal variance in axial field to produce the best energy gains.

the field generated in the plasmoid will quickly dominate the process. i doubt there is any benefit

As I understood the process, the axial field is used to start the field rotating in order to assist the process, and that it is an important part of the process. So, I think that tuning the action of the axial field has merit – especially if there’s no closed form solution available. A genetic (algorithm) search, or even a drunkards-walk, through the solution space should do to settle what the best setting should be. A fuzzy-logic controller would be more suited to a system that varies shot-to-shot, and has some characteristic that can be monitored by the controller, and used to moderate the axial field.

I’m thinking, though, that a rheostat to tune things would probably work as well – so long as the trigger is stable.

*tuning* has merit. but, once the pinch has started, there isn’t much you can do. what use would it be to affect .00000001% of the field, if you have only a few nanoseconds to sense and correct?

Tuning during the shot is not the point; optimizing shot-to-shot and as the generator runs for long periods is. The components of the chamber acquire some permanent magnetism,e.g., and influence the magnetic environment, so there isn’t either a single-number fix, or a need to play with the field during the kinking process so much as match the contribution of the axial field to the best trend. Hence my suggestion to use fuzzy logic; “a bit more of this, a bit less of that.”

From what i have read they plan to remove the permanent magnetization of the materials in the DPF by using non magnetic materials so it shouldn’t be a problem in the future.
