Description

he high luminosity upgrade of the LHC is targeted to deliver 2500 fb-1 at a luminosity of 5x10E34 cm-2s-1. Higher granularity, 140 collisions per bunch crossing and existing bandwidth limitations require a reduction of the amount of data at module level. New modules have binary readout, on-chip pT-discrimination and capabilities to provide track finding data at 40 MHz. The CMS collaboration has undertaken R&D effort to develop new planar sensors for the pixel-strip module, which has to withstand 1x10E15 1 MeV neutron equivalent flux in the innermost layer of the tracker. The module is composed of a strip sensor and a macro pixel sensor with 100 μm × 1.5 mm pixel size. Sensors were characterized in the laboratory and the effects of different process parameters on planar n-in-p sensor concepts were studied. Module prototypes were built, noise studies on a new type of module design for the PS module were performed and beam tests of the first prototype assemblies are done. Status and progress of this effort will be discussed.
