Description
In this programme we're going to concentrate on one particular experimental set-up. We're going to concentrate on the hydrogen bubble chamber, which is represented by this block here. Now before we... can say very much about the bubble chamber, we want to understand first of all how the particles get there. And so we must therefore consider the beam line, a particular beam line and the whole of the accelerator complex as being part of our experiment. Now you will remember from the text that the acceleration takes place in three stages. First of all we have a high voltage which gives the protons their initial kick. They're sent into a linear accelerator, which accelerates them in a straight line, until they meet the proton synchrotron ring. It's here that they are then led round the ring many many times until they reach maximum energy, and then they are ejected at some point and we're going to take it from this point here, the beam, that comes into this building which we call the East Hall. There the protons strike a target, produce all kinds of particles and then by a mixture of magnetic and electric fields we lead the particles that we're interested in into the bubble chamber.
