Query: Quality Assurance Test of Silicon Photomultipliers and Electronic Boards
  for STAR Event Plane Detector   The event plane detector (EPD), installed in the Solenoid Tracker at the
Relativistic Heavy-Ion Collider located at the Brookhaven National Laboratory
is a plastic scintillator-based device that measures the reaction centrality
and event plane in the forward region of the relativistic heavy-ion collisions.
We used silicon photomultiplier (SiPM) arrays to detect the photons produced in
the scintillator via the fiber connection. Signals from the SiPM arrays were
amplified by the front-end electronic (FEE) board, and sent to the
analog-to-digital converter (ADC) boards for further processing via the
receiver(RX) board. The full EPD system consisted of 24 super-sectors (SSs);
each SS was equipped with two SiPM boards, two FEE boards and two RX boards,
and they corresponded to 744 readout channels. All these boards were mass
produced at the University of Science and Technology of China, with a dedicated
quality assurance (QA) procedures applied to identify any problems before
deployment. This article describes the details of the QA method and the related
test system. The QA test results are presented along with the discussions.
