Security - Phasers
All variants of the 23rd century phaser store energy in a sarium krellide cell. Sarium krellide stores a maximum of 1.3x106 megajoules per cubic centimeter.
Parts of a Phaser
The power cell is connected in series to three control modules:
- Beam Control Assembly: The beam control assembly includes the controls which alter the beam's intensity and width, as well as the trigger.
- Safety Iinterlock: The Safety Interlock is used to identify and check the person using the phaser.
- Subspace Transceiver Assembly (STA): The STA is used as part of the safety system whilst on a Federation starship, automatically limiting power levels during firing when on board, usually to no more than heavy stun; it also has additional target sensors and processors for distance aiming.
Energy from the power cell passes through all three modules and is then routed through shielded conduits to the prefire chamber, a sphere of gulium arkenide-reinforced LiCu 521, 1.5 cm in diameter. This energy is stored temporarily by a charge barrier, which then collapses the energy, discharging it through the LiCu (the 'emitter crystal') as a pulse of energy.
The charge barrier collapse takes an average of 0.02 picoseconds, whereupon through a 'rapid nadion' effect the LiCu emitter converts the pulse into a tuned phaser discharge. As with a ship's main phaser banks, the greater the energy in the prefire chamber, the higher the percentage of nuclear disruption. Low to moderate phaser settings are calibrated to fall short of this nuclear disruption threshold, limiting the phaser discharge to stun and thermal electromagnetic effects.
