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

摘要

The ATLAS pixel detector for the HL-LHC requires the development of large area pixel modules that can withstand doses up to 10~(16) 1 MeV n_(eq) cm~(-2). The area of the pixel detector system will be over 5 m~2 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.
