Readout of GEM stacks with the CERN SRS system

The PHENIX Collaboration at the Relativistic Heavy ion Collider (RHIC) is considering a Gas-Electron Multiplier (GEM) tracker as part of a major upgrade of the PHENIX apparatus. The CERN RD51 collaboration has developed a “Scalable Readout System” (SRS) to facilitate a standard readout system which is suitable for GEM stacks. For the tests we are currently conducting, we have implemented the readout of the SRS into our bench-top DAQ system, “RCDAQ”. In addition to showing some early data from our GEM test detector, we will introduce the concepts behind RCDAQ, show the implementation of the SRS, and highlight the main features of the system.
