It's a chamber used for detecting charged particles. The chamber is filled with a superheated liquid, mostly hydrogen. As the particle moves through the chamber, the liquid vaporises around the ions, forming bubbles. The chamber can the be expanded by a piston to increase the size of the bubbles, and a photograph taken. There is a magneti field accross the chamber, causing circular paths, where the radius is proportional to the momentum of the particle, and differently charged particles spiral in different directions.

Hope that helps

wuts bubble chamber?? :frown:

its a chamber with liquid hydrogen and charged particles ionise the hydrogen particles and leaves a trace behind to create bubbles which will then reflect the light in the photograph
good luck all :frown:

spark chamber - box with charged plates and a gas in it, used to detecting charged particles. As the particle arrives it ionises the gas. a trigger system is used to increase the electric field and produce a spark wherever the particle is located

Whats a drift chamber? Our teacher never taught it to us so I assumed we didn't need to know it but it keeps poping up on these threads.

Good luck everyone! Don't stress yourselves out. You need to walk into that exam calm to be able to do well.

I doubt it would come up, but it is similar to a spark chamber - only a newer version. I didn't really revise that too much so I'm not incredibly sure on that.
