First launch of a new type fusion reactor "Wendelstein 7-X" successfully generated helium plasma
At the Max · Planck Institute in Germany, a nuclear fusion reactor "Wendelstein 7-X"Initial experiments were conducted and succeeded in plasma generation using helium.

"Wendelstein 7-X" began construction in April 2005, completed in May 2014. Tests to actually move it from there were done over a year. The figure photographed in 2011 in the middle of construction is like this.
In order to realize a nuclear fusion reactor, it is necessary to trap high temperature / high density plasma, so farTokamak typeHas been considered to be powerful, but in Wendelstein 7-XHelical type (stellator)Was adopted.
It looks like this according to "Science". The upper gray item shows the outermost cryogenic cooling system. The middle is the inside view of the cooling device, yellow is a flat superconducting electromagnet, and red is a nonplanar superconducting electromagnet. At the same time, non-planar electromagnets are not arranged in the same shape but are arranged twisting like a spiral, although they are arranged to draw a circle. The bottom shows the electromagnet and the plasma (blue) born in it.

Below is a short summary of the state of construction, but it contains a very comprehensible picture of how the electromagnet arrangement is.

This is where non-planar electromagnets are arranged. One electromagnet is roughly about the height of an adult male.

It is assembling an outside cooling device with a diameter of 18 m.
I looked down from above. A lot of parts are placed.
Schematic from here. The inside "twist" structure is like this.
Nonplanar electromagnets themselves have complicated shapes, and 50 pieces are arranged so as to draw a spiral with respect to the circle.
Twenty planar electromagnets on the outside.
Cooling device covers the whole. Plasma is born in this.
In fact the plasma that was filmed this time is.
In this case, about 1 million degrees of plasma was produced in 1 / 10th of a second using helium, but this is for testing whether plasma generation can be done without problems, and from the end of January 2016 Plasma generation using hydrogen will be performed.
For nuclear fission reactors that utilize the nuclear fission reaction of atoms, since there is no chain reaction in the nuclear fusion reactor, runaway does not occur and unlike uranium and plutonium, it is enough to use common resources such as hydrogen, so it is put into practical use It is awaited.
