Pixel IBL Stave Testing

The ATLAS pixel detector is expected to be upgraded by stage to meet the challenge of high occupancy and radiation dose at high luminosities. The first stage the installation of another inner-most pixel layer (Insertable B-Layer: IBL) on a smaller beam pipe within the current pixel detector during 2013 shutdown.  The IBL staves consist of both traditional planar sensors and the very radiation hard new 3D sensors bump-bonded to the new large FE-I4 readout ASICs. The first IBL stave is still being assembled while the summer is expecting the first batch of production staves to be tested. SLAC has been a primary contributor in establishing the stave testing system at CERN Point 1 SR1 building. The stave test readout system is in particular using the first generation prototype of the generic DAQ R&D Reconfigurable Cluster Element (RCE) concept originated from SLAC.  This is as an integrated entity of electronics hardware and software support implemented on the high bandwidth modern ATCA (Advanced Telecommunication Computing Architecture) platform with I/O capacity at several hundred times faster than the more commonly used VME systems in HEP and a prime candidate technology for wide range of future ATLAS upgrade needs.
