The Large Hadron Collider (LHC) will be improved to be able to reach about seven times its current nominal instantaneous luminosity. The High-Luminosity LHC (HL-LHC), is planned to start operation in 2027. To face the consequent increase of the particle fluence close to the proton-proton interaction point, the ATLAS detector will include in its upgraded Inner Tracker (ITk) new sensor...
The proven potential of 3D pixel at higher than 10$^{16}$ n$_{eq}/cm^{2}$ radiation fluences, in combination with a small cell approach, makes them an ideal choice for a precision timing tracker. In this study, the timing resolution of several different geometry 3D pixel cells is presented using 160 GeV SPS pion beams. Through a varied incidence angle study, field uniformity, Landau...
We present a novel scalable graphene-silicon hybrid photodiode that enables deep UV imaging. We have a created a photodiode with a reduced dead layer entrance window. Existing photodiodes are limited in sensitivity for low wavelengths due to the low penetration depth of photons of < 400 nm. Typical photodiodes have a junction implant which causes the low penetrating photons to be recombined in...
