TL;DR: In this article, the innermost ring (R0) of the end-cap part in the upgraded ATLAS inner tracker (ITk) was irradiated with 70-meV protons at CYRIC, Tohoku University (Japan) and reactor neutrons at the Jožef Stefan Institute (Slovenia) to three different 1-MeV neutron equivalent fluences: 0.5, 1 and 2 x 1015 n eq cm−2.

TL;DR: In this paper, a planar pixel detector for the inner part of the ATLAS detector upgrade of the High Luminosity LHC has been developed, where the pixel size is smaller compared to the currently operating pixel detector in ATLAS and the 2 pitch options, 50 μ m × 50 µm and 25 µm × 100 µm, are readout by the same 50 μ µm − µm pitch readout ASIC.

TL;DR: In this article, a scintillating tile/fiber calorimeter was irradiated with 2.5 GeV electrons at the KEK linac and the induced damage was evaluated in a 2 GeV electron test beam by measuring the reduction in pulse height after irradiation.

Optics of large scintillating tiles with wavelength shifting fiber readout: Application to a hadron calorimeter
TL;DR: Light yield and response uniformity of a scintillating tile/fiber system were measured for tiles with a side length up to ∼50 cm in this paper, where the SDC barrel hadron calorimeter was used as a model to evaluate the performance of a Calorimeter composed of tile and fiber systems with such a lateral nonuniformity and with light yield variation in depth.
