'confinement device' is a correct and usable idiom in written English.
Example: This study investigates the effectiveness of a new confinement device in restricting the movement of children.
A tokamak is a plasma confinement device that can be used to achieve magnetically confined nuclear fusion within a reactor.
It produces the highest plasma temperatures, densities, and confinement durations of any confinement device.
But in March 2009, using an inertial electrostatic confinement device, Wilson did it.
During the 23 years Alcator C-Mod has been in operation at MIT, it has repeatedly advanced the record for plasma pressure in a magnetic confinement device.
During the 23 years MIT's Alcator C-Mod tokamak fusion experiment was in operation, it repeatedly advanced records for plasma pressure in a magnetic confinement device.
ITER is to be a magnetic confinement device of the type called a tokamak, which has a toroidal (donut-shaped) configuration and a strong, confining magnetic field.
The results of the experiments are applied to both man-made plasma confinement devices, such as future thermonuclear fusion plants, and to plasmas confined in planetary magnetospheres.
Description of magnetic confinement devices: tokamaks, stellarators and RFPs, their design and operation.
These effects can be exploited in a variety of plasma devices, including Hall thrusters, plasma mass filters, and fusion confinement devices.
Conveyor belts, without specific powder confinement devices, spread out fine particles, causing dust pollution and generating risk for workers' health (silicosis).
Stellerators are more complex magnetic confinement devices than tokamaks, and therefore have always appealed to theoreticians possessing complicated minds and access to supercomputers, but Nature is indifferent to both.
