I. INTRODUCTION HE test stand system for the iFVTX silicon detector of the Pioneering High Energy Nuclear Interaction eXperiment

PHENIX is the largest of the four experiments currently taking data at the Relativistic Heavy Ion Collider (RHIC), and the iFVTX is a new pixel tracker which will be installed in the forward tracker region of PHENIX. Fermilab has developed a complete test stand system for the examination of FPix2.1 modules, hybrids, and pixel chips that will be installed in the iFVTX. The system is currently in use for chip, module, and wafer testing at Fermilab. The test stand architecture is flexible and can be adapted to new requirements. In this paper, the software and hardware integration will be discussed followed by an analysis of the advantages of choosing a modular approach for the system. Finally, a selection of tests supported by the system, along with sample results, will be presented and explained. Index Terms — Data Acquisition, FPix2.1, iFVTX, PHENIX, Test Stand.
