Description
The CMS detector is a multipurpose collider detector that is being
constructed at the Large Hadron Collider and is scheduled to begin taking
data in 2007. At the heart of the all-silicon tracking system is a silicon pixel
detector divided into a cylindrical barrel and forward disks. The forward pixel
system is currently being assembled and is scheduled for insertion into CMS
in 2008. There are a large number of subcomponents present in the
system, some assembled by outside vendors and others assembled at
collaborating institutions. To ensure the quality of the final detector, a
testing program has been developed to ensure the use of known good parts
at each phase of assembly. This report will focus on the testing performed
on individual detector modules. This involves a thorough test of the
functionality, noise, gain, and other characteristics of all 18 million pixels in
the full system. Results are presented on the first 20% of modules that
have been assembled and tested.
