Planar pixel detector module development for the HL-LHC ATLAS pixel system

Publication Date
  • Qc Physics


The ATLAS pixel detector for the HL-LHC requires the development of large area pixel modules that can withstand doses up to 1016 1 MeV neq cm−2. The area of the pixel detector system will be over 5 m2 and as such low cost, large area modules are required. The development of a quad module based on 4 FE-I4 readout integrated chips (ROIC) will be discussed. The FE-I4 ROIC is a large area chip and the yield of the flip-chip process to form an assembly is discussed for single chip assemblies. The readout of the quad module for laboratory tests will be reported.
