Plasma and Plasma Physics

UKAEA’s Dr Nick Walkden provides a basic introduction to the interesting world of plasma physics in this recent webinar and Q&A recording.

Hi Dr Nick, can you have plasma of mixed elements..ie air? how does that work? when ions and electrons are in a plasma soup, how do they know they are an oxygen electron or a hydrogen ion? is there stuff you can do with plasma amalgams or mixtures?

In addition to this great talk, I recommend "Plasma Physics and Controlled Fusion" by Francis F. Chen

SUPER. AWESOME. and a great help in understanding this incredible subject matter: Plasma Physics. 5 Star job. !!

During my training as a physics lab assistants from 1971, I saw a plasma for the first time during the testing of ion getter pumps. At that time it impressed me...

[whole_caveman_or_lions_den]

The first time I heard plasma was when plasma TV's were introduced, just recently started wondering what plasma is and what it's used for and why it behaves the way it does.

@18:50 doesn't that attraction of electrons towards that ion mean there are fewer electrons everywhere else, making everywhere else slightly positively charged?

[juneshgautam]

As per your example of turbulence in a cup of tea, what if I spin the cup in the same direction as I spin the spoon. Will that counteract the turbulence?

44:13 "I'm not sure I understand"
Me too, watch. Me too.

Just kidding, this was a great talk and gave a great intro to someone not at all involved in this field.

Since plasma uses the path of least resistance, is it possible to create some kind of Faraday cage to prevent changes from external influences?

[davidwilsonjunior]

As an electrical engineer Corona on high voltage was my first exposure

[hellovicki]

Really interesting. Is it possible to blend plasmas into a plasma alloy? What happens to plasma if neutrality is removed somehow?

[varunranganathan]

I believe the title of the video should be plasmer and plasmer physics

[shahidnawaz]

Sir I am Pakistani student and I am going to do research in plasma sir tell me about the modern research area

[sophiemingelbier]

What do you think about plasma physics on human being age generation .t seems to have a role on growing from child to adults?

[KaliFissure]

Wonderful introduction to the flow complexity of plasma! Thank you! 

Are there electrostatic containment methods? Make whole interior surface positive and the ionic nuclei would concentrate in middle no?

The natural meandering is so like that of a stream. The torsion caused by mean path differences inside outside causes pressure variations perturbations, meanderings. You are trying to keep it linear. Is that counter principle? Are any plasma facilities looking to intentionally cultivate filament pairs? Can you induce a curl harmonic?

[collinhauger]

Those instabilities can be corrected by chanting ohm.

[sophiemingelbier]

I am wondering impact of plasma on inondation and tsunami

[tibodeclercq]

I don't have a nice experience with Plasma Physics.
In Engineering Physics, I had a course Plasma Physics and the exercises were nothing but proving formulas and equations.

[sophiemingelbier]

I think altitude has an impact on gravity and plasma's reaction. Do you agree

[Dan-gskg]

Strange how the relation Current Density = Charge Density * Velocity is not mentioned.
