How To Use Tokamak In A Sentence
-
The stainless steel quarto plates, made out of low cobalt 304, will be used in the cylindrical section of the cryostat, which is the hull surrounding the main components of the Tokamak reactor.

-
As discussed earlier, full steady-state operation in a tokamak requires that the inductive plasma current is completely replaced by a non-inductive one.
-
A tokamak, which is what ITER will be, is basically a D-shaped car tire.

Other potential magnetic consequences of the SOLC are identified: its error field can introduce complications in feedback control schemes for stabilizing MHD activity and its toroidally non-axisymmetric field can be falsely identified as an axisymmetric field by the tokamak control logic and in equilibrium reconstruction.
-
A tokamak is a doughnut-shaped vessel in which researchers use powerful magnet fields to squeeze and heat a plasma of hydrogen isotopes until the nuclei fuse together forming helium and releasing large amounts of heat.
News
-
RFP devices have the same toroidal and poloidal components as a tokamak, but the current flowing through the plasma is much stronger and the direction of the toroidal field within the plasma is reversed.
Nuclear fusion power
-
Fusioneers have worried that bigger tokamaks would require a much stronger magnetic-field ‘bottle’ to confine the superhot plasma that fusion requires.
-
The CFNS is based on a tokamak, which is a machine with a "magnetic bottle" that is highly successful in confining high temperature more than 100 million°C fusion plasmas for sufficiently long times.
Nuclear Fusion-Fission Hybrid Saves The Future
-
In the tokamak, two powerful electromagnets create fields that are so powerful that they can hold a hot plasma in place as readily as a person can hold an orange in her hand.
-
The most common mechanism for controlling plasma reactions today is called a tokamak, originally designed by the Russian physicist Lee Artsimovich in the late 1950s.
-
As far as the dangers go, its a lot safer than nuclear fission power (the reactor types that are being used now) because it produces virtually no radiation or nuclear waste (ohmic heating of a plasma in a tokamak replaces the irradiated water if a fission reactor which produces nuclear waste).

-
These low-aspect-ratio stellarator-tokamak hybrids differ from conventional stellarators in their use of the plasma-generated bootstrap current to supplement the poloidal field from external coils.
-
* A tokamak has two directions: poloidal and toroidal.

Nuclear fusion entails forcing together the nuclei of light atomic elements in a super-heated plasma, held in a doughnut-shaped chamber called a tokamak, so that they make heavier elements and in so doing release energy.

The time - resolved neutron flux density measurement system on HT - 7 Tokamak is presented in the paper.
-
In a tokamak, the toroidal field is created by a series of coils evenly spaced around the torus-shaped reactor, and the poloidal field is created by a strong electric current flowing through the plasma.
