It is known that for the current design of planar pixel sensors, there is a drop of efficiency at the punch-through structure of the biasing system at the edge of pixels. Various geometries, as part of the ATLAS Inner Tracker (ITK) upgrade, are being investigated to reduce this inefficiency. A planar pixel sensor with multiple alternative bias rail geometries has been tested at the SPS beam...

ATLAS upgrade for foreseen High Luminosity LHC will require the high radiation tolerance on Pixel Detector. The n$^{+}$-in-p silicon technology is a promising candidate for the pixel upgrade, due to its radiation hardness and cost effectiveness. We have developed n$^{+}$-in-p planar pixel sensors produced by HPK (Japan) connected by bump bonding to the ATLAS read out chip FE-I4. The new...

27. Latest development of HPK/KEK n$^+$-in-p planar pixel sensor modules for HL-LHC and understanding their performance with TCAD simulations

We have been developing planar-process pixel sensors in p-type 6-in. silicon wafer for an application in ATLAS detector for the luminosity upgrade of the large hadron collider (HL-LHC). Our motivation is to develop a highly radiation-tolerant and cost-effective pixel sensor for covering large area of the pixel detector. In the 1st prototype pixel sensors, after irradiation and beamtest,...
