I think it is because they do not carry a charge. They are neutrons therefore they are neutrons. The LHC can accelerate protons because they carry a positive charge, for example. The LHC uses magnetic fields to accelerate particles, which will have no effect on neutrally charged particles.
The mass of an electron is very small. The electron would be accelerated to relativistic (extremely fast) speeds, which would effectively increase the mass of the electron. The change in mass of the electron would mess up the revolution of the electron.
The LHC at CERN is like all accelerators of that ilk, they require a charged particle so that the surrounding EM force can pull or push them into faster and faster speeds.
So the only two sub-atomic particles used in such accelerators are protons (plus charge) and electrons (negative charge). The LHC accelerates protons. Neutrons have no charge; so they cannot be pushed or pulled into acceleration by EM force and thus the LHC can't use them.
Cyclotron
electrons and protons
My butt is an electron
Proton is a positive particle and electron is a negative particle.
Helium has no electron affinity.
In a cyclotron, the most important condition is that of the cyclotron frequency. The frequency of the square wave oscillator connected to the dees of the cyclotron must match the frequency of revolution of the charged particle being accelerated. For ordinary ions, once the frequency is set there is no need to change or adjust the frequency. The equation for cyclotron frequency is As it is clear from the above equation that the cyclotron frequency is inversely proportional to mass of the ion. The frequency of revolution is apparently constant for ordinary ions. If an electron is accelerated in a cyclotron, it quickly picks up high-speed comparable to the speed of light because of its light mass. The speed comparable to the speed of light is called relativistic speed. At relativistic speeds, mass is not constant but varies according to the relation. As per the equation as speed increases, relativistic mass increases. This will change the frequency of revolution and the revolution will go out of phase. The acceleration will stop.
The electric field in a cyclotron appears across the gap in the D's inside which the particles are accelerated. (There is a bit more to this, but not much.) Use the link below to a related question about the construction and operation of this nuclear particle accelerator.
The final energy attained by a deuteron undergoing cyclotron acceleration depends on the design of the cyclotron. In some machines the final energy may be as low as 3MeV whilst in others, 25MeV. Above 25MeV reletavistic effects kick-in and the cyclotron needs to be more sophisticated in its design. It does depend on the cyclotron. Theres actually an equation for that. It takes into account the maximum radius of the orbit of the particles and the wavelength of the accelerating voltage. So for a given cyclotron with exactly specified values for radius and wavelength, the maximum kinetic energy of a particle depends on its rest energy and, hence, its rest mass. But heres an easy way to figure it out: If a given cyclotron can accelerate protons to an energy of say, 2 MeV, then deuterons can be accelerated to 4 MeV. Multiply by a factor of 2.
it is the magnetic field not the electric field which accelerates the ion inside the dees
The primary difference is that the cyclotron provides a "circular" path for the accelerated particles, and the linear accelerator provides a "straight tunnel" as a pathway for the accelerated particles. Both devices accelerate particles, but are suited nicely to be used in tandem The cyclotron is frequently applied as the "initiator" of a particle stream in physics labs with multiple accelerators. The cyclotron feeds the linear accelerator, which then provides a final boost to particles before directing them into a target. And this pair of devices can be set up to feed a larger "ring" accelerator. That is a "simple" three-stage setup for generating and accelerating a string of particles to ramp them up to near light speed. The accelerated particles, with their extreme energies, are then directed into selected targets and the scattering reactions observed.
Beta tron is a device for speeding up electrons to extremely high energies with the help of expanding magnetic field. The beta tron differs from cyclotron in the two fundamental respects - 1) in beta tron the electron are accelerated by expanding magnetic field 2)the circular orbit has a constant radius.

A cyclotron operator is responsible for running a cyclotron. The average salary of a cyclotron operator is $64,000 per year.
He was as his wikipedia article makes plain. Electron microscope, linear accelerator, atomic bomb, cyclotron, etc.
The cyclotron was discovered by one Ernest Lawrence.
the alpha particle will accelerate slower and follow a tighter/smaller spiral outward than the proton.
