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.
The following is a list of characters that appear in 2025, by order of first appearance. All characters are introduced by the soap's executive producer, Lucy Addario. The 38th season of Home and Away began airing from 13 January 2024. [1] Detective Mark Townsend was introduced during the same episode.
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.
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 ...
In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text. The entity must either be predefined (built into the markup language) or explicitly declared in a Document Type Definition (DTD). The format is the same as for any entity reference: &name;
These systems were originally referred to simply as pinch or Bennett pinch (after Willard Harrison Bennett), but the introduction of the θ-pinch (theta pinch) concept led to the need for clearer, more precise terminology. The name refers to the direction of the current in the devices, the Z-axis on a Cartesian three-dimensional graph. Any ...

The q profile in a reversed field pinch The poloidal field in a reversed field pinch. A reversed-field pinch (RFP) is a device used to produce and contain near-thermonuclear plasmas. It is a toroidal pinch that uses a unique magnetic field configuration as a scheme to magnetically confine a plasma, primarily to study magnetic confinement fusion.
