This document provides a set of one-page summaries for each of the 
major systems in the GlueX detector. These are not meant to be
detailed, complete discussions, but rather a quick overview of the
entire detector. These summaries briefly outline the 
purpose of the system, the requirements placed on the system by
physics goals of GlueX, and a brief description including channel 
count. This continues with  a discussion of the expected raw signals 
as well as needed amplification and final readout of the detector.
A brief discussion of the current stage of R\& D is given with 
outstanding questions pointed out. Finally, the groups and manpower
needed for final construction of the element are identified as 
well as an estimate of the required construction time.

It should be pointed out that due to the availability of both manpower
and interest within the collaboration, some systems are much further
along than others. In particular, the Lead-glass Calorimeter is
being built out of glass blocks from an existing device and a great
deal of experience exists. The Forward Drift Chambers were taken on
by the Ohio University group in late 2002, while the collaboration is
currently in discussions with the University of Tennessee and Oak
Ridge groups about taking responsibility for the Cherenkov system.
Independent of this, the collaboration believes that assuming timely
funding of the detector, a viable plan exists for getting physics 
out of the detector in a timely fashion.
