Toroidal'naya kamera s magnitnymi katushkami, accorting to Wikipedia.
This is a truly beautiful device. The torus is a recurring shape in nature. I think our own inventions will ultimately follow, ever more closely, the shapes and forms of nature's, and be better for it.

ruzuzu commented on the word tokamak
"ITER is based on the 'tokamak' concept of magnetic confinement, in which the plasma is contained in a doughnut-shaped vacuum vessel. The fuel—a mixture of Deuterium and Tritium, two isotopes of Hydrogen—is heated to temperatures in excess of 150 million°C, forming a hot plasma. Strong magnetic fields are used to keep the plasma away from the walls; these are produced by superconducting coils surrounding the vessel, and by an electrical current driven through the plasma."

ruzuzu commented on the word tokamak
“Harnessing this form of nuclear power, though, has proven extremely difficult, requiring heating a soup of subatomic particles, called plasma, to hundreds of millions of degrees – far too hot for any material container to withstand. To work around this, scientists developed a donut-shaped chamber with a strong magnetic field running through it, called a tokamak, which suspends the plasma in place.“

Is it an acronym or more specifically a clipped compound? I don't know Russian, but it seems like it's coming from To-ka-ma-k, not T.O.K.A.M.A.K. or T.K.M.K but maybe that's how you pronounce those letters?
