Yes, linear accelerators are smashing particles together to better learn the characteristics of their interaction (including how they form more complicated aggregations).
There are quantum particles. Such particles have properties, like spin, charge, momentum, energy, parity, mass, etc. Those properties determine how those particles interact with other particles. We are attempting to learn the specifics of those interactions. Note that energy is *one* of those properties. It is not, itself, fundamental in any way that is different than, say, charge, or spin.
But you can add just energy to the system. It is *something*.
No, you cannot just add energy to a system. To add energy, you have to apply a force. In other words, you have to interact with the system by some other system. Interactio between particles can, and does, change the dynamic properties of the particles involved. This includes energy and momentum, for example.
Energy is a property of the particles, not something that can be separated from them. Energy doesn't exist as a 'thing in itself', but solely as a property of such things: quantum particles.

thats right. its only our perspective that makes it look like its something separate. Like accelerating a car. you changed a property, kinetic energy, but the motor is part of the car.
also, changing the kinetic energy didn't change the total energy of the system. the total energy is the same, it just looks different to you.
You accelerate a car by applying a force to it. That force comes from a system other than the car (the force of the road on the car).
Yes, the total energy of the 'system' changes *if* you consider the system to be the car. If you consider the system to be the car plus the road, then not.
And, when it comes to cosmology, there are some inherent difficulties involved in even talking about the 'total energy of even a universe of finite extent. That is because the energy is one component of a four dimensional vector and there is no single way to parallel transport a vector in a curved spacetime. So, in some ways, energy is *less* fundamental than, say, charge, which is the same for all observers.

The energy that heats up one set is not nothing, and is not known to be a set of quantum particles. In the linear accelerator are quantum particles speeding up and smashing quantum particles ? No. Why build the damn thing if they are ?
Two *identical* sets of particles will have the same temperature because they will have the same kinetic energy. To be identical means to share all properties.
