TL;DR: The ALICE silicon pixel detector (SPD) constitutes the two innermost layers of the inner tracking system (ITS), and the basic building block of the SPD is the half-stave carrying two detector ladders as discussed by the authors.
Abstract: The ALICE silicon pixel detector (SPD) constitutes the two innermost layers of the inner tracking system (ITS). The basic building block of the SPD is the half-stave carrying two detector ladders. The half-stave is equipped with a multi-chip module (MCM) and an optical fibre link for control and readout. A 5-layer aluminium/polyimide bus ensures the distribution of power and signals on each half-stave. The half-staves are mounted on a light-weight carbon-fibre structure with an integrated evaporative cooling system. An overview of the SPD development and the current status of the construction are presented.

TL;DR: The ALICE Silicon Pixel Detector (SPD) as mentioned in this paper uses 1200 bump-bonded readout chips produced in a commercial 0.25 μ CMOS process, each chip has 8192 pixels of size 50 × 425 μ m 2.
Abstract: The ALICE Silicon Pixel Detector (SPD) will include 1200 bump-bonded readout chips produced in a commercial 0.25 μ CMOS process. Each chip has 8192 pixels of size 50 × 425 μ m 2 , which leads to about 10 million readout channels in the whole detector system. Test beam measurements were recently carried out at the CERN SPS using a positive proton/pion beam as well as a 158 A GeV/c heavy ion beam (In) with a fixed Pb target. Analysis show good performance of the ALICE chip and assemblies in the positive beam as well as in the high multiplicity In beam. Preliminary results from data analysis show good performance of the SPD and fulfill the ALICE requirements.

TL;DR: The silicon pixel detector (SPD) is the innermost element of the ALICE inner tracking system (ITS) and prototypes of the full read-out chain have been produced and tested.
Abstract: The silicon pixel detector (SPD) is the innermost element of the ALICE inner tracking system (ITS). The on-detector electronic system consists of several ASICs in a commercial 0.25μm CMOS process (radiationhardened by design), a low-mass multi layer Kapton cable for power and signal distribution (pixel bus), and a multi-chip module that includes a custom designed, very compact optical transceiver. The control and readout data transmission is done via optical fibres. Prototypes of the full read-out chain have been produced and tested. Integration issues and test results are presented and discussed.
