Description
A silicon vertex tracker (VTX) is one of the upgrade programs
in the PHENIX experiment to measure the production of
heavy (charm and bottom) quarks in Au+Au and polarized p+p collisions.
The production of heavy quarks is a powerful tool
to study both the properties of a dense partonic matter created in
high energy heavy ion collisions and the gluon contribution to
the spin structure of proton in polarized p+p collisions.
The VTX provides the precise measurement of heavy flavors
and a clear separation of charm and bottom contributions.
The VTX comprises the four layers of the barrel detectors.
The two inner layers consist of silicon pixel detectors
and the two outer layers consist of silicon stripixel detectors.
The VTX was constructed and installed during the shutdown period
of year 2010.
In this poster presentation,
we report the details of the VTX construction and installation.
