Which is why the cannon shell is matter. The energy radiating off of the internal plasma shield acts as a barrier, protecting the antimatter until it hits the target. Then, standard explosive charges detonate inside the shell, destroying the generator, exposing the antimatter to matter. This is all supplemented with a "may not work in real life" disclaimer.
