Description
The CMS pixel detector is an all-silicon tracking device located
closest to the interaction point. Following the first long shut down
of the LHC, in order to maintain the high performance of the tracker,
the pixel detectors must be upgraded to handle the increased amounts
of event pileup. One of the components of the upgrade is the forward
pixel detector, which uses a High Density Interconnect (HDI) to
connect the pixels and the readout chip. During the shutdown, a pilot
system will be installed in the forward pixels to test the performance
of the new design. In addition to this pilot program, 50 HDI's are
currently being visually and electrically tested by a team from the
University at Buffalo, located on-site at Fermilab. The current
results of these tests will be presented.
