The PAX Collaboration is being involved in experiments employing polarized internal targets. In this framework, the team is since years exploring techniques to produce a beam of polarized antiprotons by means of the spin-filtering technique. Another physics objective of the collaboration, is a test of time reversal invariance by investigating the T-violating null observable Ay,xz that could be accessed by using a vector polarized proton beam and a tensor polarized deuteron target. To support these investigations, the collaboration has developed and commissioned a multipurpose high-acceptance vertex detector. The detector of 4 silicon telescopes arranged in a diamond configuration around a storage cell. It has been designed to cope with proton (anti)proton and proton-deuteron reactions in the energy range between and 30 MeV and 200 MeV In a commission run, the detector was installed in the “PAX” low ß section of the COSY storage and employed as a target polarimeter by making use of the analyzing power in p-d elastic scattering. This paper is dedicated to technical part of different systems of the detector. The talk will address mechanical construction, arrangement of the silicon detectors and electronic readout together with additional supplementary devices such as Atomic Beam Source and Breit-Rabi polarimeter.
