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, the tokamak's performance is limited by the plasma's stability and confinement. One approach to improve the tokamak's efficiency is by 'compressing' the torus of plasma, which has been explored in various configurations, including the CT (Compact Torus), spheromak, and dynomak. In this article, we will delve into the concept of compressing tokamak plasma, its history, and the current state of research.
History of Compressing Tokamak Plasma
The idea of compressing tokamak plasma dates back to the 1970s, when researchers began exploring ways to improve the plasma's confinement. One of the earliest attempts was the Compact Torus (CT) experiment, which aimed to create a high-density plasma by compressing a toroidal field. The CT experiment was conducted at the University of Wisconsin-Madison in the 1970s and showed promising results, but it was eventually abandoned due to technical difficulties.
In the 1980s, researchers turned their attention to the spheromak, a type of toroidal plasma that is generated by a magnetic field. The spheromak's compact size and high plasma density made it an attractive alternative to the tokamak. However, the spheromak's stability and confinement were found to be limited, and it was eventually replaced by the tokamak as the primary fusion reactor design.
Dynomak: A New Approach to Compressing Tokamak Plasma
In recent years, researchers have revisited the concept of compressing tokamak plasma with the development of the dynomak. The dynomak is a type of compact torus that uses a magnetic field to compress a toroidal plasma. The dynomak's design is based on the idea of creating a high-density plasma by compressing a toroidal field, similar to the CT experiment.
The dynomak has been the subject of several scientific papers, including a 2019 paper published in the journal Physics of Plasmas (1). The paper presents a detailed analysis of the dynomak's design and operation, including its magnetic field configuration and plasma confinement. The authors conclude that the dynomak has the potential to achieve high plasma densities and confinement times, making it an attractive alternative to the tokamak.
Scientific Papers on Compressing Tokamak Plasma
Several scientific papers have been published on the topic of compressing tokamak plasma. Some notable examples include:
- Compact Torus Experiment (CTX): A 1977 paper published in the journal Physics of Fluids (2) presents the results of the CT experiment, which aimed to create a high-density plasma by compressing a toroidal field.
- Spheromak Experiment (SPH): A 1982 paper published in the journal Physics of Fluids (3) presents the results of the SPH experiment, which aimed to create a high-density plasma by compressing a toroidal field.
- Dynomak Experiment (DYN): A 2019 paper published in the journal Physics of Plasmas (1) presents the results of the DYN experiment, which aimed to create a high-density plasma by compressing a toroidal field.
Simulations of Compressing Tokamak Plasma
Simulations have played a crucial role in the development of compressing tokamak plasma. Researchers have used numerical simulations to model the behavior of the plasma and magnetic field in various configurations, including the CT, spheromak, and dynomak.
One notable example is a 2018 paper published in the journal Physics of Plasmas (4), which presents a numerical simulation of the dynomak's operation. The authors use a 3D magnetohydrodynamic (MHD) code to simulate the dynomak's magnetic field configuration and plasma confinement. The results show that the dynomak has the potential to achieve high plasma densities and confinement times.
