Plasma Physics: A Comprehensive Introduction

In summary, plasma is a distinct phase of matter that consists of ionized gas with free electric charges that make it electrically conductive. It was first identified in 1879 by Sir William Crookes and named "plasma" by Irving Langmuir in 1928. Plasmas are the most common phase of matter in the visible universe and have many applications in fields such as astronomy and fusion technology. The NRL Plasma Formulary is a useful resource for formulas and information related to plasmas.

In physics and chemistry, a plasma is an ionized gas, and is usually considered to be a distinct phase of matter. "Ionized" in this case means that at least one electron has been dissociated from a significant fraction of the [atoms or] molecules. The free electric charges make the plasma electrically conductive so that it couples strongly to electromagnetic fields. This fourth state of matter was first identified by Sir William Crookes in 1879 and dubbed "plasma" by Irving Langmuir in 1928, because it reminded him of a blood plasma.

Plasmas are the most common phase of matter. The entire visible universe outside the solar system is plasma: all we can see are stars. Since the space between the stars is filled with a plasma, although a very sparse one (see interstellar- and intergalactic medium), essentially the entire volume of the universe is plasma (see astrophysical plasmas). In the solar system, the planet Jupiter accounts for most of the non-plasma, only about 0.1% of the mass and 10−15 of the volume within the orbit of Pluto. Alfvén also noted that due to their electric charge, very small grains also behave as ions and form part of a plasma (see dusty plasmas).

I was browsing the Naval Research Laboratory and found this nice resource on formulas, constants, vector identities and other useful information concering plasmas and plasma physics - http://wwwppd.nrl.navy.mil/nrlformulary/index.html
files available in postscript and pdf formats

The NRL Plasma Formulary has been the mini-Bible of plasma physicists for the past 25 years. It is an eclectic compilation of mathematical and scientific formulas, and contains physical parameters pertinent to a variety of plasma regimes, ranging from laboratory devices to astrophysical objects.

Thank you for providing a comprehensive introduction to plasma physics. It is fascinating to learn that plasma is the most common phase of matter in the visible universe and that it was first identified by Sir William Crookes in 1879. The references you have provided are also helpful in understanding the various applications of plasma physics, from astronomical objects to fusion and magnetoplasmadynamic systems. I will definitely check them out to further my understanding of this interesting field of study.
 

FAQ: Plasma Physics: A Comprehensive Introduction

What is plasma physics?

Plasma physics is the study of the fourth state of matter, in which gas particles become ionized and form a highly energized state of matter. Plasma is commonly found in stars, lightning, and fluorescent lights.

How is plasma different from other states of matter?

Plasma differs from other states of matter in that it is made up of charged particles, rather than neutral particles. This makes it highly electrically conductive and responsive to electric and magnetic fields.

What are some applications of plasma physics?

Plasma physics has a wide range of applications, including fusion energy research, space propulsion, plasma display panels, and materials processing. It also plays a crucial role in understanding and predicting space weather.

What are some key concepts in plasma physics?

Some key concepts in plasma physics include plasma confinement, which is the process of containing and controlling plasma, and plasma instabilities, which refers to the tendency of plasma to become unstable and disrupt its own confinement. Other important concepts include plasma heating mechanisms, plasma diagnostics, and plasma simulation techniques.

What are some current research topics in plasma physics?

Current research topics in plasma physics include developing more efficient and sustainable forms of fusion energy, understanding the properties of plasmas in extreme conditions, such as in space or in laboratory experiments, and studying the effects of plasma on materials and biological systems. Other areas of research include plasma turbulence, plasma-surface interactions, and plasma astrophysics.
