Poloidal Simulation Variables

Overview

The Poloidal Field Generator simulation is a component of the fusion reactor simulation. It simulates the magnetic fields designed to maniuplat ethe shape of the main containment field to improve reaction efficiency. There are four polidal generators.

The polidal simulation has three functions, details below.

Inputs

The poloidal simulation has two inputs:

Poloidal Field Generator Input (PFGI) is user-controlled simulating power input to the generator.

Applied Toroidal Force (ATF) is output from the Toroidal Generator simulation

Outputs

The polidal simulation has two outputs. These are currently output as a single value, representing the avergae of the four poloidal generators. It is anticipated that future versions will provide more granular output:

Active Field Plane Focus (AFPF): simulates the shape of the active (ie that plasma reacts to) containment field. It is output back to the toroidal simulator.

Containment Field Pitch (CFP): simulate show steep the curve on the containment field is. It is output to both the toroidal simulator (where it moodfies the shape of the containment field) and MHD simulators where it simulates the effect of field pitch on the efficieny of plasma flow.

Poloidal Generator Output (PFGO)

This simulates the output response of the filed generators to input power.

Active Field Plane Focus (AFPF)

Ths simulates the shape of the main containment field (once it has been manipulated by the poloidal field).
