Introduction
What are fully ionized gases?
A gas is a state of matter in which the molecules are widely separated and move freely in random directions. When a gas is subjected to a strong electric field or a high temperature, some of its atoms may lose one or more electrons, creating positively charged ions and negatively charged electrons. This process is called ionization. A gas that contains a significant number of ions and electrons is called an ionized gas or a plasma.
Depending on the degree of ionization, plasmas can be classified into partially ionized or fully ionized. In a partially ionized plasma, some atoms remain neutral, while in a fully ionized plasma, all atoms are stripped of their electrons. Fully ionized plasmas are usually found at very high temperatures, such as in the cores of stars, in thermonuclear reactors, or in lightning bolts.
Who is Lyman Spitzer Jr.?
Lyman Spitzer Jr. (1914-1997) was an American physicist and astronomer who made important contributions to the fields of plasma physics and astrophysics. He is widely regarded as the father of space telescopes, as he proposed the idea of placing a large telescope in orbit around the Earth in 1946, which eventually led to the launch of the Hubble Space Telescope in 1990.
Spitzer was also a pioneer in the study of fully ionized gases and their applications to fusion energy and stellar dynamics. He founded the Princeton Plasma Physics Laboratory in 1951 and initiated the development of the stellarator, a device that uses magnetic fields to confine plasmas for fusion reactions. He also formulated the Spitzer-Härm theory, which describes how heat is transported by electrons in plasmas.

The properties of fully ionized gases
One of the main challenges in studying fully ionized gases is to understand how they behave under different conditions of temperature, pressure, electric and magnetic fields, and radiation. Unlike ordinary gases, fully ionized gases are strongly influenced by the interactions between the charged particles, which give rise to complex phenomena such as collective effects, waves, instabilities, and turbulence. In this section, we will review some of the basic properties of fully ionized gases and how they can be measured or calculated.
Temperature and pressure
The temperature of a fully ionized gas is a measure of the average kinetic energy of the ions and electrons. The temperature can vary widely depending on the source of heating or cooling. For example, the temperature of the solar core is about 15 million degrees Celsius, while the temperature of the interstellar medium is about 10 degrees Celsius.
The pressure of a fully ionized gas is a measure of the force exerted by the ions and electrons on a unit area. The pressure can be expressed as the sum of three components: the thermal pressure, which depends on the temperature and density; the electric pressure, which depends on the electric field; and the magnetic pressure, which depends on the magnetic field. The pressure can also vary widely depending on the conditions. For example, the pressure of the solar core is about 250 billion atmospheres, while the pressure of the interstellar medium is about 10^-12 atmospheres.
Electrical conductivity and resistivity
The electrical conductivity of a fully ionized gas is a measure of how easily it can carry an electric current. The electrical conductivity depends on several factors, such as the temperature, density, composition, and degree of ionization. Generally speaking, higher temperatures and densities lead to higher conductivities, while higher degrees of ionization lead to lower conductivities.
The electrical resistivity of a fully ionized gas is a measure of how much it opposes an electric current. The electrical resistivity is inversely proportional to the electrical conductivity. The electrical resistivity also depends on several factors, such as the temperature, density, composition, and degree of ionization. Generally speaking, higher temperatures and densities lead to lower resistivities, while higher degrees of ionization lead to higher resistivities.
Thermal conductivity and viscosity
The thermal conductivity of a fully ionized gas is a measure of how easily it can transfer heat by conduction. The thermal conductivity depends on several factors, such as the temperature, density, composition, degree of ionization, and magnetic field. Generally speaking, higher temperatures and densities lead to higher thermal conductivities, while higher degrees of ionization and stronger magnetic fields lead to lower thermal conductivities.
The viscosity of a fully ionized gas is a measure of how much it resists deformation by shear stress. The viscosity depends on several factors, such as the temperature, density, composition, degree of ionization, and magnetic field. Generally speaking, higher temperatures and densities lead to lower viscosities, while higher degrees of ionization and stronger magnetic fields lead to higher viscosities.
Radiation and opacity
The radiation of a fully ionized gas is a measure of how much energy it emits or absorbs by electromagnetic waves. The radiation depends on several factors, such as the temperature, density, composition, degree of ionization, and frequency spectrum. Generally speaking, higher temperatures and densities lead to higher radiation rates, while higher degrees of ionization lead to lower radiation rates.
The opacity of a fully ionized gas is a measure of how much it blocks or scatters electromagnetic waves. The opacity depends on several factors, such as the temperature, density, composition, degree of ionization, and frequency spectrum. Generally speaking, higher temperatures and densities lead to higher opacities, while higher degrees of ionization lead to lower opacities.
The applications of fully ionized gases
Fully ionized gases have many applications in various fields of science and technology, ranging from fundamental research to practical engineering. In this section, we will review some of the main areas where fully ionized gases play an important role.
Plasma physics and fusion energy
Plasma physics is the branch of physics that studies the behavior and interactions physics has many subfields, such as plasma dynamics, plasma chemistry, plasma diagnostics, plasma waves, plasma instabilities, plasma turbulence, and plasma simulation. Plasma physics also has many applications, such as plasma processing, plasma medicine, plasma lighting, plasma propulsion, and plasma display. One of the most important and challenging applications of plasma physics is fusion energy. Fusion energy is the process of generating energy by fusing light nuclei into heavier ones, releasing a large amount of energy. Fusion energy is the source of power for stars, such as the Sun. Fusion energy has many advantages over other forms of energy, such as being clean, safe, abundant, and sustainable. However, achieving fusion energy on Earth is not easy. It requires creating and maintaining a fully ionized gas at very high temperatures and pressures, and confining it for a long enough time to allow fusion reactions to occur. There are two main approaches to achieve fusion energy: magnetic confinement and inertial confinement. Magnetic confinement uses magnetic fields to confine the plasma in a toroidal or spherical shape, such as in a tokamak or a stellarator. Inertial confinement uses lasers or ion beams to compress and heat a small pellet of fuel to ignite fusion reactions. Astrophysics and space science
Astrophysics is the branch of physics that studies the origin, structure, evolution, and behavior of astronomical objects and phenomena, such as stars, planets, galaxies, black holes, nebulae, cosmic rays, and gravitational waves. Astrophysics uses many tools and methods, such as observations, theories, models, simulations, and experiments.
Space science is the branch of science that studies the exploration and utilization of outer space for scientific and technological purposes. Space science includes many disciplines, such as astronomy, cosmology, astrobiology, planetary science, space engineering, space weather, and space medicine. Space science uses many instruments and platforms, such as telescopes, satellites, probes, rovers, rockets, and space stations.

Magnetohydrodynamics (MHD) is the branch of physics that studies the dynamics of electrically conducting fluids, such as plasmas, in the presence of magnetic fields. MHD combines the principles of fluid mechanics and electromagnetism to describe how magnetic fields affect the flow and transport of plasmas, and how plasmas generate and modify magnetic fields. MHD has many applications in plasma physics, astrophysics, geophysics, engineering, and medicine.
Shock waves are rapid changes in pressure, density, temperature, and velocity that propagate through a medium. Shock waves can be caused by various events, such as explosions, supersonic flights, collisions, or abrupt changes in magnetic fields. Shock waves can compress, heat, accelerate, or deflect the medium they encounter. Shock waves can also trigger chemical reactions, phase transitions, or instabilities in the medium.
Fully ionized gases are often subject to magnetohydrodynamic effects and shock waves. For example, in the solar wind, the interaction between the plasma and the interplanetary magnetic field can create MHD waves and instabilities that propagate and transfer energy throughout the heliosphere. Similarly, in supernova explosions, the blast wave from the star can create shock waves that sweep up and ionize the surrounding interstellar gas, forming a shell of hot plasma that emits radiation. Fully ionized gases can also produce their own shock waves when they move at high speeds or encounter obstacles or boundaries.
Laser physics and optics
Laser physics is the branch of physics that studies the generation, amplification, manipulation, and application of coherent and monochromatic light beams, known as lasers. Laser physics uses the principles of quantum mechanics, electromagnetism, optics, and statistical physics to describe how lasers work and how they can be controlled and modified. Laser physics has many applications in science, technology, industry, medicine, and entertainment.
