The capacitive coupling between an active sensor and a readout ASIC has been considered in the framework of the CLIC vertex detector study. The CLICpix Capacitively Coupled Pixel Detector (C3PD) is a High-Voltage CMOS sensor chip produced in a commercial $180$ nm HV-CMOS process for this purpose. The sensor was designed to be connected to the CLICpix2 readout chip. It therefore matches the...
The Phase-II upgrade of the LHC will result in an increase of the instantaneous
luminosity up to about $5\times 10^{34}$ cm$^{-2}$s$^{-1}$. To cope with the
challenges the current Inner Detector will be replaced by an all-silicon Inner Tracker (ITk)
system. The Pixel Detector will have to deal with occupancies of about 300~hits/FE/s
as well as a fluence of $2\times...
The current inner tracker of the ATLAS experiment is foreseen to be replaced at the High Luminosity era of the LHC to cope with the occuring increase in occupancy, bandwidth and radiation damage. It will be replaced by an all-silicon system, the Inner Tracker (ITk). This new tracker will have both silicon pixel and silicon strip sub-systems aiming to provide tracking coverage up to |η|<4.
For...
Facing the high luminosity phase of the LHC (HL-LHC) to start operation around 2026, a major upgrade of the tracker system for the ATLAS experiment is in preparation. The expected neutron equivalent fluence of up to $3 \times 10^{16}\; \text{n}_\text{eq}/\text{cm}^2$ at the innermost layer of the pixel detector poses the most severe challenge. Thanks to their low material budget and high...
The ATLAS collaboration is planning a major upgrade of the current detector systems in order to operate at the increased luminosity provided by the High Luminosity LHC (HL-LHC) scheduled for operation from 2025.
In order to operate at these increased luminosities, the inner most detector system known as the Inner Tracker (ITk) must be lower mass, higher granularity and more radiation hard...
