Fusion By 'compressing' Tokomak Plasma (CT, Spheromak, Dynomak Etc.)
Introduction
The quest for sustainable and clean energy has led to the development of various fusion reactors, with the tokamak being one of the most promising designs. However, achieving controlled nuclear fusion in a tokamak is a complex task, requiring the confinement of hot plasma at incredibly high temperatures. One approach to enhance plasma confinement is by 'compressing' the torus of plasma in a tokamak, a concept that has garnered significant attention in recent years. In this article, we will delve into the idea of compressing tokamak plasma, exploring the scientific papers and research that have been conducted on this topic.
What is Tokamak Plasma Compression?
Tokamak plasma compression involves the use of external forces to compress the torus of plasma in a tokamak, thereby increasing the plasma pressure and density. This compression can be achieved through various methods, including the use of magnetic fields, inertial confinement, or a combination of both. The goal of plasma compression is to create a more stable and controlled plasma environment, which can lead to improved confinement times and increased fusion yields.
History of Tokamak Plasma Compression
The concept of compressing tokamak plasma dates back to the 1970s, when researchers first proposed the idea of using magnetic fields to compress the plasma. However, it wasn't until the 1990s that the first experiments were conducted to test this concept. Since then, numerous research groups have explored various methods of plasma compression, including the use of magnetic fields, inertial confinement, and hybrid approaches.
Magnetic Field Compression
One of the earliest approaches to compressing tokamak plasma was through the use of magnetic fields. Researchers proposed the use of external magnetic fields to compress the plasma, thereby increasing the plasma pressure and density. Several experiments were conducted to test this concept, including the Tokamak Fusion Test Reactor (TFTR) at Princeton Plasma Physics Laboratory (PPPL) and the Joint European Torus (JET) at the Culham Centre for Fusion Energy (CCFE).
Inertial Confinement
Inertial confinement is another approach to compressing tokamak plasma. This method involves the use of high-powered lasers or particle beams to compress the plasma, creating a high-pressure and high-density plasma environment. Several experiments have been conducted to test this concept, including the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) and the Omega Laser Facility at the University of Rochester.
Hybrid Approaches
Hybrid approaches to compressing tokamak plasma involve the combination of magnetic fields and inertial confinement. This method aims to leverage the strengths of both approaches, creating a more stable and controlled plasma environment. Several research groups have explored hybrid approaches, including the use of magnetic fields to compress the plasma and high-powered lasers to further compress the plasma.
Spheromak and Dynomak Approaches
In addition to tokamaks, researchers have also explored the use of spheromaks and dynomaks as potential fusion reactors. Spheromaks are toroidal devices that use a magnetic field to confine the plasma, while dynomaks are a type of spheromak that uses a dynamic magnetic field to compress the plasma. Several experiments have been conducted to test these concepts, including the Spheromak Experiment (SPHEX) at the University of Washington and the Dynomak Experiment (DYNEX) at the University of California, Los Angeles (UCLA).
Simulations and Modeling
Simulations and modeling play a crucial role in the development of fusion reactors, including those that use plasma compression. Researchers use computational models to simulate the behavior of the plasma, predicting the effects of compression on plasma confinement and fusion yields. Several research groups have developed advanced simulation tools, including the National Ignition Facility (NIF) simulation code and the Princeton Plasma Physics Laboratory (PPPL) simulation code.
