Homework Help: How frequently a collision takes place in a collider

  1. Oct 30, 2009 #1
    1. The problem statement, all variables and given/known data

    If its circumference is 27km, and there are 4 equally spaced points where the beams collide, show a collision takes place every 22 microseconds at each one of the collision points

    2. Relevant equations

    I don't know where to start, which equation should I use?

    3. The attempt at a solution

    Hi there,

    From my point of view, your problem is lacking quite a few information. From the information you are giving, it sounds very much like the CERN's LHC.

    To figure out how many collisions take place, you need to know at least the current density of the beam, and the speed of the particles.

    That's what I thought, but that is all the information that I have been given to solve it...

    ah, it says they are accelerated up to 45GeV...
