2. Simulation of HR GaAs:Cr Timepix3 detectors with Allpix2

Dr Petr Smolyanskiy (IEAP CTU in Prague)

09/05/2022, 14:40

New Featues

Recent advantages in crystal growth have facilitated the production of high resistivity (HR) chromium compensated gallium arsenide (GaAs:Cr), which has become an alternative to silicon, especially in X- and gammas-ray detection and imaging, where such sensors profit from their higher absorption efficiency.

To explore charge transport properties of the HR GaAs:Cr material we measured the...

9. Radial strip detectors in Allpix-Squared

Radek Privara (Palacky University (CZ))

09/05/2022, 15:05

New Featues

The Allpix-Squared simulation toolkit has long been used by the ATLAS ITk Collaboration to perform simulations of pixel and strip silicon detectors.
In this contribution, a new functionality added into the toolkit is presented, enabling simulations of ATLAS ITk strip end-cap detectors featuring a trapezoidal sensor shape with detection strips fanning out radially from a common focal point....

10. Simulation of hybrid pixels using precise TCAD simulations

Keerthi Nakkalil (APC,CNRS/IN2P3 and Université`de Paris), Marco Bomben (APC & Université de Paris, Paris (FR))

09/05/2022, 15:30

Applications & Studies

In view of the High Luminosity LHC phase the ATLAS collaboration is preparing a new all silicon tracking detector - the Inner Tracker (ITk).
At the core of the new tracker there will be 5 barrel layers instrumented with hybrid pixel detectors with fine pitch (50x50 or 25x100 um).
The new detector will have to sustain radiation damage levels up to 10 times larger than the actual tracker....

5. Cosmic Strips Telescope Simulation with Allpix

Maximilian Caspar (DESY)

09/05/2022, 15:55

Applications & Studies

We are simulating the performance of the ATLAS ITk Strips EC System Test as a Cosmic Muon Telescope with the Allpix Squared framework. A couple of modifications to the Allpix (and Corryvreckan) frameworks have been made to deal with the particularities of the cosmic particle flux.

Planned contents of the talk:

• The ATLAS ITk Strips System Test
• ITk Strips Endcap Modules (with a...

6. Development and simulation of a new preshower detector for the FASER experiment at the LHC

Rafaella Eleni Kotitsa (Universite de Geneve (CH))

10/05/2022, 13:25

Applications & Studies

The design of a new high-granularity pre-shower detector for the FASER experiment at LHC is in progress, with the purpose of measuring and discriminating electromagnetic showers generated by photons with O(TeV) energies and separation down to 200 µm. The new pre-shower will comprise six planes of monolithic silicon pixel detectors with hexagonal pixels of 65 µm side.
The detector simulation...

13. Simulations of 65 nm silicon sensors using Allpix Squared

Manuel Alejandro Del Rio Viera (Deutsches Elektronen-Synchrotron (DE))

10/05/2022, 13:50

Applications & Studies

The Tangerine project’s goal is to develop the next generation of small collection electrode monolithic silicon pixel detectors using the 65nm CMOS imaging process which offers a higher logic density and overall lower power consumption compared to previously used processes.
A combination of TCAD and Monte Carlo (MC) simulations are used in order to understand the processes and parameters...

12. Beam telescope simulations in Allpix Squared

Sara Ruiz Daza (Deutsches Elektronen-Synchrotron (DE))

Applications & Studies

Beam telescopes are used to investigate future particle detector prototypes, and to do this efficiently they must provide excellent position and time resolution at the device under test location. One of the goals of the Tangerine Project is to develop a beam telescope based on sensors created in a 65 nm CMOS imaging process. In order to study the tracking performance and choose the best...

Applications & Studies

The 100µPET project, a SNSF SINERGIA between UNIGE, EPFL and HUG, aims at producing a small-animal PET scanner with unprecedented volumetric spatial resolution by using multi-layer monolithic silicon pixel detectors.
The Allpix${}^2$ framework is central for the detector's parameters optimization. Different detector geometries and electrical parameters are studied in order to optimize the...

17. Using Allpix Squared for proton computed tomography

Christopher Krause (Technische Universitaet Dortmund (DE))

10/05/2022, 15:25

Applications & Studies

Proton therapy is, due to its higher precision of energy deposition, an effec-
tive alternative to conventional x-ray therapy. Occurring uncertainties due to
the use of x-ray computed tomography in treatment planning can be reduced
through the use of proton computed tomography. To accurately predict the
range of the protons in tissue, it is necessary to reconstruct the tracks of...
