STAR is the only running experiment at Relativistic Heavy Ion Collider (RHIC) and is dedicated to exploring the properties of Quantum Chromodynamics. The main focuses at RHIC in the following years (2022-2025) are cold QCD and spin physics. Therefore, the STAR Collaboration has installed a suite of new detectors in the forward rapidity region (2.5 < eta < 4) this year (2021), enabling a program of novel measurements in p+p, p+A and A+A collisions. The new subdetectors comprise a Forward Calorimeter System, with electromagnetic and hadronic calorimetry. As well as a Forward Tracking System, which consists of 3 layers of silicon mini-strip detectors and 4 layers of small-strip Thin Gap Chambers.
In this presentation, the detailed description on the deign and manufacturing of the mechanical structure of the STAR forward silicon tracker, will be given.
