Theta-pinch, or θ-pinch, is a type of fusion power reactor design. The name refers to the configuration of currents used to confine the plasma fuel in the reactor, arranged to run around a cylinder in the direction normally denoted as theta in polar coordinate diagrams.
Screw pinch – A combination of a Z-pinch and theta pinch [15] (also called a stabilized Z-pinch, or θ-Z pinch) [16] [17] Reversed field pinch or toroidal pinch – This is a Z-pinch arranged in the shape of a torus. The plasma has an internal magnetic field. As distance increases from the center of this ring, the magnetic field reverses ...
The FRC was first observed in laboratories in the late 1950s during theta pinch experiments with a reversed background magnetic field. [3] The original idea was attributed to the Greek scientist and engineer Nicholas C. Christofilos who developed the concept of E-layers for the Astron fusion reactor.
A concept of Z-pinch fusion propulsion system was developed through collaboration between NASA and private companies. [1] The energy released by the Z-pinch effect would accelerate lithium propellant to a high speed, resulting in a specific impulse value of 19400 s and thrust of 38 kN. A magnetic nozzle would be required to convert the released ...
However, the LSX used a method of forming FRCs called a theta-pinch, which does not allow FRCs to be further sustained and heated. The US Department of Energy funded the TCS program as an extension of LSX, in order to demonstrate the RMF method of sustaining FRCs formed via the theta-pinch method.

Pseudorapidity values shown on a polar plot. In particle physics, an angle of zero is usually along the beam axis, and thus particles with high pseudorapidity values are generally lost, escaping through the space in the detector along with the beam.
