We will present the first characterization of a low mass, vertically integrated modular system optimized for the demanding thermal environments expected in the innermost layers of LHC experiments after the PH2 upgraded luminosity. The system is composed by a stack of three silicon layers for a total thickness of less than 1mm. From the top a radiation hard, 230 micron thick 3D silicon sensor (fabricated at CNM-Barcelona) with the same design of the ones used for the ATLAS-Insertable-B-Layer, integrated to a 100 micron thick FE-I4 front-end electronics pixel chip and a silicon micro-channel layer designed to circulate evaporated CO2. The paper will show the system electrical and thermal functionalities, discuss results on the use of 3D printed ceramic components which could further improve the detector system’s large area design and conclude with future plans.
