We describe the technical design and show results of first measurements of a network based on the Timepix3 and the Katherine readout (with Gigabit Ethernet interface) installed in the ATLAS cavern in the LHC in January 2018. The network consists of four Timepix3 detectors, arranged in two two-layer telescopes. [...]

/ATLAS Collaboration
Four hybrid pixel detectors of Timepix3 technology, installed in the ATLAS experiment, were continuously taking data from April 2018 until the end of the Run-2 data taking period (December 2019). These detectors are synchronized with each other and the LHC orbit clock. [...]

Determination of Luminosity With Thermal Neutron Counting Using TPX Detectors in the ATLAS Cavern in LHC Proton-Proton Collisions at 13 TeV
/ Sopczak, André (IEAP CTU, Prague) ; Ali, Babar (IEAP CTU, Prague) ; Begera, Jakub (IEAP CTU, Prague) ; Bergmann, Benedikt (IEAP CTU, Prague) ; Billoud, Thomas (Montreal U.) ; Biskup, Bartoloměj (IEAP CTU, Prague) ; Burian, Petr (IEAP CTU, Prague) ; Caforio, Davide (IEAP CTU, Prague) ; Heijne, Erik (IEAP CTU, Prague) ; Janeček, Josef (IEAP CTU, Prague) et al.
A network of Timepix (TPX) devices installed in the ATLAS cavern has the unique capability of measuring the luminosity with thermal neutron counting in Large Hadron Collider proton-proton collisions at 13 TeV. Compared with the hit-counting method, the method of thermal neutron counting has the advantage that it is not affected by induced radioactivity. [...]

New developments of pixel detectors based on GaAs sensors offer effective registration of the transition radiation (TR) X-rays and perform simultaneous measurements of their energies and emission angles. This unique feature opens new possibilities for particle identification on the basis of maximum available information about generated TR photons. [...]

A network of ten GaAs:Cr semiconductor Timepix detectors with GaAs:Cr sensors was installed in the ATLAS cavern at CERN's LHC during the shutdown periods 2015–2016 and 2016–2017 in the framework of a cooperation between ATLAS and the Medipix2 Collaboration. The purpose was to augment the existing system of measuring and characterising the radiation environment in the ATLAS cavern that is based on ATLAS-TPX devices with pixelated silicon sensors. [...]

An application of the use of MPX detectors for the measurement of induced radioactivity in the Large Hadron Collider (LHC) experiment environment is presented. The sixteen ATLAS-MPX detectors measured the associated photon ambient dose equivalent rate (H$^*$(10) rate) in ATLAS due to the LHC operation. [...]
