description | CLIC is an option for a future high energy linear $e^{+}e^{−}$ collider at CERN in the post-LHC era. The CLIC machine is designed to reach centre-of-mass energies ranging from a few hundred GeV up to 3 TeV. To achieve high precision measurements, e.g. of the Higgs- width, challenging requirements are imposed on the CLIC detector. A single point tracking resolution of 7 μm and a material budget of 1-2%$X_{0}$ per layer are required for the tracker. Moreover, to suppress background hits from beam-beam interactions, a precise time slicing of hits of 10 ns is needed. To address these requirements, a large area silicon tracker is foreseen for the detector at CLIC. In this context, integrated technologies are promising candidates to achieve large scale production and low material budget. The Investigator chip is a test chip developed for the ALICE Inner Tracking System upgrade, implemented in a 180 nm CMOS process on a high resistivity substrate. It contains various test-matrices with analogue functionality, which are read out by external sampling ADCs. This paper introduces the process and technology of the Investigator chip, describes the data taking and reconstruction setup and presents results on spatial and timing resolutions, as well as efficiency measurements, for a pixel pitch of 28 μm. |
