A new pixel Front-End (FE) IC is being developed in a 130
nm technology for use in the upgraded ATLAS pixel detector. The new pixel FE will be made of smaller pixels (50×250
μm vs. 50×400
μm for the ...present FE, FE-I3), a much improved active area over inactive area ratio, and a new analog pixel chain tuned for low power and new detector input capacitance. The higher luminosity for which this IC is tuned implies a complete redefinition of the digital architecture logic, which will not be based on End-of-Column data buffering but on local pixel logic and local pixel data storage. An overview of the new FE is given with particular emphasis on the new digital logic architecture and possible architecture variations.
AbstractSeveral methods for the determination of the mass of the top quark with the ATLAS detector at the LHC are presented. All dominant decay channels of the top quark can be explored. The ...measurements are in most cases dominated by systematic uncertainties. New methods have been developed to control those related to the detector. The results indicate that a total error on the top mass at the level of 1 GeV should be achievable.
