The Planar Pixel Sensors R&D Project (PPS) for the ATLAS Upgrade (exchanged with T 55.8) — •Daniel Muenstermann on behalf of the ATLAS PPS collaboration — TU Dortmund, Experimentelle Physik IV, D-44221 Dortmund
The ATLAS detector is a multi-purpose experiment at the Large Hadron Collider (LHC). Contrary to previous planning that relied on a design luminosity of 1034 cm−2 s−1, it is now anticipated to increase LHC’s luminosity in a continuous way up to more than 2 · 1034 cm−2 s−1 in 2016. In a second step, a major upgrade of LHC could enable as much as 1035 cm−2 s−1 in 2021.
The luminosity enhancement will increase both, radiation levels as well as occupancy of the inner tracker. To cope with this, upgrades of the inner tracker will be necessary.
In 2008, an ATLAS R&D project[1] was founded to investigate the suitability of the proven and reliable planar pixel technology for the upgrades. The collaboration comprises 15 institutes from 7 countries with more than 70 scientists.
The presentation will briefly describe current plans for the ATLAS upgrades, the requirements for the sensors of the inner tracker and the role of planar pixel sensors. An overview of the workpackages within the R&D project will be given.
