چکیده انگلیسی
We present the status of the silicon vertex tracker for the PHENIX experiment. The purpose of the PHENIX detector is to investigate very high-density and high-temperature matter, so called Quark Gluon Plasma in heavy ion collisions upto 100 GeV/nucleon and spin structure of the nucleon with polarized proton beam up to 250 GeV/beam. We plan to build the silicon vertex tracker to identify the charm and bottom quark decay by using displaced decay vertex, with two inner pixel layers and two outer stripixel layers. The design goal of the displaced vertex resolution is at the level of 30-50 μm in high charged multiplicity environment with minimum material budget requirement to avoid generating background for outer detectors in the PHENIX.
