Magnetic enclosure: big improvement

@@ Line 15: / Line 15: @@
 == Magnetic enclosure ==
-Tokamak devices can be scaled down greatly by raising the intensity of the plasma confining magnetic field.
+For a basic introduction please consult the Wikipedia article about "magnetic confinement fusion"
-The power fluxes become very high though. (Higher than atmospheric reentry of a space-shuttle)
+[https://en.wikipedia.org/wiki/Magnetic_confinement_fusion]
-It's hard to project how the performance of superconductors will further increase. This limits the range of predictions severely. (See: [[non mechanical technology path]]).
+=== Field strength and plant size ===
-Using light diamondoid materials for the structural frame parts and superconductor carrier strips (cables) that have low radiation exposure can reduction the overall weight by a lot. This is especially important for application in spaceships. Currently (2016) it still seems rather impossible to reach anything near light enough.
+The limit in achievable magnetic field strength has led to the construction giant prototype plants (see ITER).
-The requirement to absorb most of the neutron radiation before it reaches coils and cryo-system creates a natural lower end size limit for magnetic enclosure fusion.
+It is yet unknown what kind of fields will be achievable once advanced APM gives us much more control over matter and lets us mechanosynthesize super-exotic thermodynamically metastable superconductor compounds.
