The Scientific Experiment That's Never Been Done

What about it? Well, it's a story about particles and atoms, and in my story there's some people studying their behavior. The shoot energy at various materials. They compare how it behaves when the material is at room temp, as well as frigid and hot temps. When gamma passes a wall at room temp in a controlled experiment, that's more like it. But if that wall gets frozen to where the gas around it starts freezing, then will the experiment, which is controlled so that the beam is emitted with equal power, result in the beam going into the wall further, closer, or equal? And how about if the wall is heated? Will that effect the distance that the beam travels? How about if we shoot a beam through a pocket of air multiple times? And everything is the same each time, except that we differ air pressure. Will that effect the behavior? What magic is there still left for us to discover, hidden in the realms of the Quantum?
