Does a charge have spin outside an atom?

    Is spin of electron taken into account when people accelerate electron in LHC?

    The LHC accelerates protons, not electrons.

    Electrons (and all other particles with spin) have a spin outside of atoms.

    This spin is taken into account at electron- positron colliders.

    The spin is not relevant at high-energetic proton-(anti)proton collisions, as you don't care about elastic collisions there*. Deep inelastic collisions (the interesting stuff) are collisions between parts of the protons, where you cannot control the spin anyway.

    *don't tell that the scientists of the TOTEM experiment. But the proton spin is so small that I don't think they care about it.
