WEAPONS LOCKER - LOWER PERSONAL PHASERS The primary defensive arms carried by Starfleet crew members are two types of small phasers, Type I and Type II. Both are high-energy devices sized for personal use and can be stowed in or attached to oneÕs uniform. As with the larger ship-mounted arrays, the Type I and II phasers convert stored energy into tightly controllable beams for a variety of applications. Phasers operate on a modified version of the rapid nadion effect (see index topic listing for 'PHASERS - Bridge' ). Rapid nadions produce a pulsed protonic charge in the heart of the device, a stabilized LiCu 521 superconducting crystal (lattice formula Li<>Cu>O). LiCu 521 is an advanced version of the 518 crystal mass-produced for the shipÕs Type X Main Phaser and exhibits a 3% improvement in thermodynamic efficiency at 92.65%. Æ
