Guess what this is a photo of!

Not a thing to do with sound or music.

Here is a pic of a the plasma device when not operating. There are variety of these things out there but they all have a common purpose.

the bit inside a plasma TV?
this is quite hard for a female you know ;0(
I don't have one in my handbag!

 

[qmax]

Not in your TV. Ask yourself, where and why would you use a device the emits a stream of plasma.

Here is another one, to give you some sense of scale.

Has this got anything to do with Einstein-coefficients approach, it is shown that synchrotron radiation can be amplified when a monoenergetic electron stream is gyrating in a helical path in the static magnetic field of a cold magnetoactive plasma.

 

[les]

just a thought ;0)

I couldn't say.

Tokamak?

Nope. Clue: it is space junk. Russians liked it more than the US.

Is it anything to do with the Hubble? Blimey this is really hard lol

The Hubble, as well as anything else in orbit would have equipment that would perform the function this does. Don't know if Hubble uses this particular variety.

mmmmmmmmm I'm really stuck on this one, sorry not much good! :0(

I've just about spelled it out as to functionality. What does every spacecraft need that emits/ejects something, in this case plasma?

 

[les]

well you may have spelled it out in your mind, but I can't guess it. Sorry mate I tried! I think there was not a lot of response to this so I give up.

Hopefully I will have time to get back on it this evening! I'm in the same boat as you Les! Maybe that's the problem--we're in a boat, but we need to be in a space ship!

If everyone is stymied, I can put up something else.

This thing is an ion thruster. It is used for station keeping and maneuvering on satellites and other spacecraft. It is one of several thruster types.

I'll post another pic in a while.

 

[Barbara L]

Darn, I was just about to say that! Just kidding of course, I wasn't anywhere near!

Ion thruster - Wikipedia, the free encyclopedia

The pics are of the Hall-effect version.

Ok, try this one. Something a little more down to Earth. What is the odd building in front?
