I tried to take a picture with the highest possible denisity of Science per cubic meter I could find. I think this angle of Alcator C-Mod probably does it. Look at all this science!

Next-Generation Power: Is Fusion Back On The Table?

Nuclear fusion is a powerful form of energy generation, but it has been seen as extreme and dangerous. However, this has not stopped the study and testing of fusion as a possible mid-century power solution.

[literallymechanical]

I do plasma science and nuclear fusion research in the Nabisco Laboratory.

“Nabisco?” You ask. “Surely that’s just some obscure scientist’s name. You’re not referring to the National Biscuit Company, right?”

Nope, that’s exactly what I’m talking about.

My lab was made possible by the public’s love of Oreos and Nutter Butters.  The old Alcator C-Mod tokamak, and the upcoming SPARC tokamak, only exist because Chips Ahoy! and Fig Newtons are so delicious.

I still don’t like Wheat Thins, though.

Torque

Okay so here’s the absolute unit from an angle I haven’t posted before

See that oval-shaped window down at the bottom? Let’s take a peek inside.

That’s a view of the center column of the torus. Like if you were to look at a donut from the edge, but the donut were hollow, and instead of a hole in the middle there was a pillar covered in molybdenum tiles. Let’s take closer look

See how those tiles are twisted clockwise? That’s not on purpose. What happens is that the crazy strong magnetic flux in the torus induces an electric current with the tile. And when you put a current-carrying piece of metal in a magnetic field, it applies a force to that metal. That’s how magnetic braking in electric cars works, for example.

The magnetic field in the torus was strong enough that it torqued these tiles so hard they twisted in their mountings.

That’s some crazy powerful torque. Some incredibly impressive torque, with super dense, strong magnetic fields. Just, torque for days.

The technical term for torque that’s beefy enough to yoink molybdenum tiles off of inconel superalloy studs is:

Torcc.

NUKLIR FUSI SEPERTI MATAHARI (BUKAN FISI SEPERTI ATOM) DILAKUKAN DI MIT

NUKLIR FUSI SEPERTI MATAHARI (BUKAN FISI SEPERTI ATOM) DILAKUKAN DI MIT

ENERGI adalah salah satu permasalahan terbesar bagi manusia. Sumber energi yang dipakai saat ini berasal dari berbagai hal mulai dari sinar mahatari dan bahkan hingga penggunaan energi fosil.

Penggunaan energi Matahari dan penggunaan energi seperti Matahari bekerjaadalah dua hal yang semakin berkembang saat ini. Khusus penggunaan energi seperti Matahari bekerja akan memerlukan keadaan khusus yang…

The Alcator C-Mod Tokamak

For 40 years MIT’s Plasma Science and Fusion Center (PSFC) has been exploring nuclear fusion as a source of energy through a series of tokamaks. The C-Mod is the third in a series of Alcator tokamaks developed at MIT since the 1960s. Characterized by a donut-shaped vacuum chamber wrapped in high-field magnets, the Alcator approach makes it possible to produce very dense and well-confined plasmas in a relatively compact device. (The name "Alcator" comes from alto campo torus = high field torus.)  Its metal (molybdenum) walls can accommodate high power densities. Alcator C-Mod has made significant contributions to the world fusion program in the areas of plasma heating, stability, and confinement of high field tokamaks.Alcator C-Mod is the only tokamak in the world operating at and above the ITER design magnetic field and plasma densities, and it produces the highest pressure tokamak plasma in the world, approaching pressures expected in ITER.

Fusing atoms make a very loud and very eerie sound.

Alcator C-Mod (Alto Campo Toro) Tokamak

Alcator C-Mod is a tokamak (magnetically confined nuclear fusion device) that is part of MIT's Plasma Science and Fusion Center. It has the highest magnetic field and the highest plasma pressure of any tokamak in the world, and represents the largest fusion reactor operated by any university.

Unfortunately, Alcator C-Mod has been slated to be shut down in October of this year, per the Fiscal Year 2014 budget request. The outcome is uncertain, pending an FY 2014 Congressional budget. The FY 2013 House budget funded Alcator C-Mod but the Senate did not, so FY 2013 funding was carried out under a Continuing Resolution rather than a real budget.
