  1. 219. INVITED: Design challenges of hybrid pixel detectors for spectral imaging
    Xavi Llopart Cudie (CERN)
    27/06/2022, 14:00
    Oral

    Hybrid pixel detectors with spectral imaging capability have multiple energy bins in each pixel capable of creating ‘colour’ images of an incoming polychromatic X-ray beam. The energy information, which is extracted for each incoming photon, can be used for image contrast enhancement, improved material identification or reduction of beam hardening artifacts in Computed Tomography. One...

    Oral

    Timepix4 is a versatile readout chip with 55 µm pixels, developed by CERN on behalf of the Medipix4 collaboration. Detector group at Deutsches Elektronen-Synchrotron (DESY) develops readout systems for the Timepix4 chip that can be used for experiments at modern synchrotrons and free-electron lasers (FELs). Timepix4 has two operating modes. Detectors with this chip operated in photon counting...

  3. 160. First tracks and initial timing results with Timepix4 Detectors
    Martin Van Beuzekom (Nikhef National institute for subatomic physics (NL))
    27/06/2022, 14:50
    Oral

    A single arm beam telescope based on the recently developed Timepix4 ASIC was built in order to perform first tests of synchronous multiple-detector readout and track reconstruction. The Timepix4 is a hybrid pixel detector readout ASIC designed to record time-of-arrival (TOA) and time-over-threshold (TOT) simultaneously in each pixel. It has a 448x512 pixel matrix with square pixels at a 55...

  4. 52. The new monolithic ASIC of the preshower detector for di-photon measurements in the FASER experiment at CERN
    Sergio Gonzalez Sevilla (Universite de Geneve (CH))
    27/06/2022, 15:10
    Oral

    The FASER experiment at the LHC is designed to look for new, long-lived fundamental particles. To extend its discovery potential, a W-Si preshower detector is currently under construction, with the objective of enabling the discrimination of photon pairs with O(TeV) energies and separation down to 200 µm. The detector will be based on a new monolithic silicon pixel sensor in 130nm SiGe BiCMOS...

  5. 183. A flexible, customizable and open-source software for the Timepix4 ASIC configuration and read-out
    Viola Cavallini (Universita e INFN, Ferrara (IT))
    27/06/2022, 15:30
    Oral

    We present a new C++ software for the configuration and read-out of Timepix4, a
    large 4-side buttable ASIC developed by the Medipix Collaboration for high-rate
    radiation imaging with improved energy and time resolution.
    The software is organized in a structure of classes that allows to configure and
    manage both the Timepix4 ASIC and the Control Board for data-handling and
    interface with...
