Cross Section of a Detector
 
To give you an idea of the paths that particles 
will take through a detector, 
here is a cross-section view of a detector, 
looking down the tube the colliding 
beams come from. Note the different places where various particles will be 
detected.
Physicists can figure out the type of particle based on where that particle 
appeared in the detector.Test yourself and see if you can 
figure out a particle 
type by analyzing its path through a detector.
