So, it's a design using magnetic mirrors?
I was asking what happend with this way of building a fusion reactor. The last that I know is that was used on the 60's.
Tokamaks are the direct evolutionary step up from magnetic mirrors because these had problems with with electron containment at the mirrors. A circular design removes the mirrors and therefore this problem. Unless these guys have completely novel mirror configuration, they must run intonth same issue because electron and proton trajectories are quite different at these energies.
