Non-Fusion-Related Plasma Physics?

In summary: I'm also studying plasma physics and working on a project to model the dynamics of a laser-plasma interaction.In summary, plasma physics is important for astrophysics, but there is a lack of money and research in this field. There are applications for plasma technology beyond nuclear fusion, such as in laser-driven electron accelerators and waste disposal.

Hi everyone.

I am interested in studying plasma physics, but not so much in studying nuclear fusion.

Is there a market for plasma physics research that is not geared toward nuclear fusion technology?

Thanks

Plasma physics is extremely important for astrophysics, especially the physics of compact objects, accretion, jets, gamma ray bursts, supernovae, etc. There is less money and very little experiment in this field however. Not to mention that its entirely academic, no industry.

That is what I feared.
Thanks.

I suppose one could earn one's living teaching math/physics, while doing plasma research on the side then?

If you're not dead set on "pure" physics, one of the applications of plasma physics is spacecraft propulsion. Try looking up some papers on plasma physics from APS or IEEE.

Will do. Thanks. I'll still keep an eye on what's going on with fusion energy too.

It's just a guess, I don't know if there's any research needed, but what about plasma TVs?

Yeah, I never thought of that.
I guess that there are also industrial applications of plasma technology.

One area of non-fusion research is laser-driven electron accelerators (AKA plasma wakefield accelerators). These can accelerate particles to GeV's over a much shorter distance than current accelerators. There is a lot of interest in this for medical technologies, because right now accelerators for cancer therapy are too big and expensive for most hospitals. Laser-drive accelerators would supposedly be smaller and cheaper. See more information here: http://en.wikipedia.org/wiki/Plasma_acceleration

Plasma-arc waste disposal is another area, though I would imagine this is mostly engineering.

Take a look at the applied areas of research here for some more info: http://en.wikipedia.org/wiki/Plasma_(physics )

Inductively coupled plasmas are used for emission spectroscopy for determination of elements (including impurities) in alloys.
http://en.wikipedia.org/wiki/Inductively_coupled_plasma
http://www.cee.vt.edu/ewr/environmental/teach/smprimer/icp/icp.html
or search google for "Inductively-coupled plasmas"

There is plasma-etching as well - http://en.wikipedia.org/wiki/Reactive_ion_etching

Plasmas are used in propulsion - http://en.wikipedia.org/wiki/Pulsed_inductive_thruster

Plasmas can be used for surface modification including PVD.

Thanks for the responses everyone.

I think I like radio propagation in plasma environments (ie the ionosphere), the medical use, and space propulsion best. However, my concerns about fusion tech (60 yrs of being "on the cusp") may also apply to plasma propulsion. (Correct me if I am wrong!)

There are other schemes of laser-plasma interactions for accelerating particles. I'm an undergraduate working on ion acceleration from thin foil targets in the radiation pressure acceleration (RPA) scheme. My work is a mix of analytic theory and computational science.

1. What is non-fusion-related plasma physics?

Non-fusion-related plasma physics is the study of plasma, which is a state of matter consisting of highly ionized gas, in applications outside of nuclear fusion. This can include research on plasma-based technologies such as plasma display panels, plasma thrusters, and plasma medicine.

2. How is non-fusion-related plasma physics different from fusion-related plasma physics?

The main difference is in the focus of the research. Non-fusion-related plasma physics is primarily concerned with the behavior and applications of plasma in non-fusion settings, while fusion-related plasma physics is focused on understanding and controlling plasma for the purpose of achieving nuclear fusion reactions.

3. What are some practical applications of non-fusion-related plasma physics?

Non-fusion-related plasma physics has numerous practical applications, including in the fields of material processing, surface modification, and environmental remediation. Plasma can also be used in advanced propulsion systems for spacecraft, as well as in medical treatments such as sterilization and cancer therapy.

4. How is non-fusion-related plasma physics studied?

Non-fusion-related plasma physics is studied using a combination of theoretical models, numerical simulations, and experimental techniques. Researchers may use specialized facilities such as plasma reactors or tokamaks to create and study plasma in controlled environments.

5. What are the challenges in non-fusion-related plasma physics research?

Some of the main challenges in non-fusion-related plasma physics research include understanding and controlling the complex dynamics of plasma, developing efficient and reliable plasma sources, and finding ways to scale up plasma-based technologies for practical applications. Additionally, safety and environmental concerns must be considered when working with plasma, as it can be a high-energy and potentially hazardous form of matter.
