But for a beam focused from a cannon that field would need to be extended and shaped along the path of the blast -- the reactions aren't directional and would tend towards the widest arc possible.

I'd agree that conventional metals are almost certainly augmented either by extreme density or whatever dodgy Trek physics are popular in sci-fi this week for force fields, but a weapon being a shaped fusion reaction (rather than just drawing power from that reaction for explosive force -- there has to be particulate matter in there somewhere, it isn't travelling at light speed and can be dodged) is extremely unlikely and counter-intuitive.
