Hotter than the Sun: JET – Earth’s biggest fusion reactor, in Culham


Re: scaling up is the answer?

The SEM fusor is a kind of linear design: sidewards the deuterium ions and electrons are confined by a relatively modest magnetic field of about 1 or 1,5 tesla, and vertically by an electrostatic field generated by a couple of charged rings and spheres. In the computer simulation the particles stay confined, with speeds up to 3E6 m/s (for fusion is needed about 2E6 m/s). As in a Farnsworth-Hirsch fusor, the ions move more or less also back and forwards towards the centre of the vacuum chamber, only now there isn't an inner grid. To find out if this is really an easy way of accomplishing nuclear fusion a real experimental setup should be built...
