TRANSPORTER SYSTEMS INTRODUCTION

	Extravehicular transport to and from the ship is accomplished by a 
number of transporter systems, which allow personnel or equipment to be 
transported at ranges up to 40,000 kilometers.
	Transport for crew and guests is provided by four personnel 
transporters located on Deck 6 of the Saucer Section. Two additional 
personnel transporters are located on Deck 14 in the Engineering Section.
	Cargo transport is provided by four low-resolution transporters 
located in the Deck 4 cargo bay complex, and four more located in the Deck 
38/39 cargo bay complex. These units are primarily designed for operation at 
molecular (non-lifeform) resolution for cargo use, but they can be set for 
quantum (lifeform) resolution transport if desired, although such usage 
would entail a significant reduction in payload mass capacity.
	Emergency evaluation from the ship is provided by six emergency 
transporters, four of which are located in the Primary Hull, with two 
additional units in the Secondary Hull. These transporters are equipped with 
high-volume scan-only phase transition coils and are capable of transport 
from the ship only; they cannot be used for beam-up. These emergency 
transporters are designed to operate at reduced power levels compared to 
standard units, but have therefore reduced range and Doppler compensation 
capabilities. Typical range is about 15,000 km, depending on available power.
	Each pair of transporters is designed to share a single pattern buffer 
tank, generally located on the deck directly below the actual transport 
chambers. The emergency transporters are designed to access the pattern 
buffers from the primary personnel transporters to supplement their own 
buffers. This doubling of hardware results in only a 31% reduction in payload 
capacity of the shared pattern buffers, but yields nearly a 50% increase in 
system throughput in emergency situations.
	The Enterprise exterior hull incorporates a series of seventeen 
transporter emitter array pads. These conformal emitters incorporate long-
range virtual-focus molecular imaging scanners and phase transition coils, 
and are strategically located to provide 360-degree coverage in all axes. 
There is sufficient overlap of emitter coverage to provide adequate operation 
even in the event of 40% emitter failure.  Æ
