Neutronic weapon
Neutronic weapons were directed energy weapons carried by Penk's starship, a heavily-armed and armored ship used to stage Tsunkatse matches. 

When Neelix compared the ship to a "traveling carnival" in 2376, Harry Kim rebutted by noting the ship's neutronic weaponry, as well as its covariant shield-protected reinforced hull plating. ()
