Electron accelerators exist, and at least one e-e- collider was built (VEP-1), but generally the colliders are e-e+

Above describes the largest ever built. It was decommissioned to make way for the LHC (same tunnel).

To my very limited understanding, at TeV energies the nature of the colliding particles defines little the produced particles. They must just collide. So many particles are produced in a collision that the conservation rules have little influence on individual products.

 

I'm not quite convinced that the initial collisions produce many neutrinos. The processes to neutrinos tend to be slow. At least the experiments at the LHC use intermediate beams (of muons?) that take tens of metres to decay partially and produce neutrinos then.

 

A very strong constraint is synchrotron radiation, which lets particles lose power when they turn, more so with lighter electrons. This is why the LHC uses protons or atomic nuclei.

 

Though, protons and their internal structure reportedly make the analysis of the collisions more difficult, and elementary particles like electrons would bring finer results. One research direction would go back to straight electron accelerators, provided the energy can be given within few km. Present technology with superconducting cavities doesn't permit it, so designers hope to use the electric field of a strong light pulse to accelerate the electrons. µm-sized patterns of transparent material could give a longitudinal component to the electric field, despite in vacuum it's perpendicular to the propagation direction. Sums of tilted and slowed beams maybe, if accurate enough.
