As far as I understand it, this Large Hadron Collider is some kind of an atomic test. It'll probably lead to bigger and more powerful nuclear weapons and also much more bigger and powerful nuclear reactors.
Yes other than anti matter which is still a relatively complex science to be understood anytime soon. Proton or even neutron “spallation” in reactors to replace other more expensive means of neutron absorption by critical material to create a sustained and controlled chain reaction is possible in the near future. However to replace the normal method of shooting a sub-critical material into critical material in nuclear bombs to create an uncontrolled chain reaction by proton or neutron beam smashing I don’t think is feasible yet.
