ATLAS is one of the four big LHC experiments and currently its Pixel-Detector is being upgraded with a new innermost 4th layer, the Insertable B-Layer (IBL). The upgrade will result in better tracking efficiency and compensate radiation damages of the Pixel-Detector. Newly developed front-end electronics and the higher than originally planned LHC luminosity will require a complete re-design of...

We present the design and initial prototype results of a pixellized proton beam profile monitor
for the COMET experiment at J-PARC. The active element of the detector is single crystal diamond grown
by chemical vapor deposition (sc-cvd). The goal of the COMET experiment is to look for charged lepton flavor
violation by direct $\mu$ to e conversion at a sensitivity of $10^{-18}$. In the...

The high luminosity upgrade of the Large Hadron Collider (HL-LHC) foreseen for 2022 will allow the experiments at the collider to collect data at a luminosity of $5~\times~10^{34}$ cm$^{-2}$s$^{-1}$, enhancing the discovery potential for new physics.
The precise determination of vertices in the high radiation environment close to the HL-LHC interaction points demands the development of solid...

This work presents new avalanche pad detectors with low gain (LGAD) fabricated with a technology based on APD but with a modified doping profile, in order to have detectors suitable to be used for tracking in high energy physics experiments (such as colliders) and resistant to the high radiation fluencies expected in the future LHC upgrade at CERN. If a significant improvement of the...

The first upgrade of the ATLAS Pixel Detector is the Insertable B-Layer (IBL), just installed in May 2014 in the core of ATLAS. Two different silicon sensor technologies, planara n-in-n and 3D, were used, connected with the new generation 13o0nm IBM CMOS FE-I4 readout chip via solder bump-bonds.
Production quality control tests were set up to verify and rate the performance of the...

The ATLAS Experiment is reworking and upgrading systems during the current LHC shut down. In particular, the Pixel detector is inserting an additional inner layer called Insertable B-Layer (IBL). The Readout-Driver card (ROD), the Back-of-Crate card (BOC), and the S-Link together form the essential frontend data path of the IBL’s off-detector DAQ system. The strategy for IBLROD firmware...

The CMS collaboration will upgrade the CMS pixel detector in 2016/2017. For this upgrade the readout chip (ROC) had to be modified. An improved readout logic, larger data buffers and the digital readout scheme promise a significant increase in hit detection efficiency at the high particle flux expected in the LHC environment of a luminosity of $2\times 10^{34}$ cm$^{-2}$s$^{-1}$. To test the...

We have been developing an X-ray detector system using a 64-pixel silicon avalanche- photodiode (Si-APD) linear array (pixel size: 100 μm × 200 μm) and pulse counting electronics for multichannel scaling (MCS). The Si-APD linear array consists of 64 pixels 100 × 200 μm^2, with a pixel pitch of 150 μm and a depletion depth of 10 μm. The fast response of Si-APD and the MCS system are used for...

Silicon based sensors have become the dominant technology for the tracking systems of most modern particle physics experiments. The demand for these sensors is increasing and the existing production capabilities might not be sufficient to fulfill the demands of the future upgrades of the LHC experiments.
To establish a new supplier for the production of silicon strip and pixel sensors a...

In the Phase-II Upgrade of the Large Hadron Collider, the instantaneous
luminosity will be increased up to about 5*1034 cm-2s-1, which creates many
challenges for future detectors. This necessitates a fundamental redesign of the
ATLAS Inner Tracker (ITk) to cope with increased radiation damage and increased occupancy in the sub-detectors.
Several...

The Pixel Detector is the innermost part of the CMS Tracker. Therefore it has to prevail in the hardest environment in terms of particle fluence and radiation. Also it is one of the most important detectors of CMS: it gives essential information for vertex reconstruction which is crucial for every analysis.
The efficiency of the Pixel Detector can decrease throughout a run by several...

The instantaneous luminosity of the Large Hadron Collider (LHC) is being increased in several steps over the next 10 years to maximize its discovery potential for new physics. However, at a luminosity of twice the design luminosity of the LHC of $1 \times 10^{34}$ cm$^{−2}$s$^{−1}$, the performance of the current CMS pixel detector is degraded by substantial deadtime incured by the readout...
