Im in dark matter and not high energy or accelerator physics, though my PhD was in neutrino oscillations using a beam line. The accelerator works by
constantly circulating bunches, each bunch is basically a small cloud of protons (in the case of the HLC) that are confined to a small volume. Each of
these bunches is passed through RF cavities that impart energy onto the bunch. I dont know how many bunches are in the accelerator at any one time,
though for the one being built inJapan for the neutrino experiment used 5 or 6 bunches in the main accelerator that where cycled in unison.
Once the bunches obtain the desired energy, they magnetically focused to collide (in a collider they are accelerated in opposite directions, there
are basically two beam pipes that are brought together in the experimental hall)
It is not really a one shot thing, the object runs and does this all the time, all synchronized and in tune.
The collisions themselves are simply when the clouds of particles pass through each other, they have a chance of two protons colliding, or coming
close enough to interact. If they do, the interaction occurs and depending on a few different factors and a bit of randomness, you produce particles
moving out perpendicular to the beam.
There are beam dump or target experiments, but thats not how the LHC works. The images are built up event by event, but the analysis is performed
using billions of events.
Sound, I am not sure, I would expect a humming noise, probably similar to a motor running the cooling systems for the magnets. The machine itself im
not sure would sound more than the mains humming noise of power supplies.
I know that pulsed magnets can ring... a single shot or multi shot pulsed magnet can make a ringing noise similar to the sound of hitting a hammer on
