During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new pixel layer, the Insertable B-Layer (IBL), was to maintain or improve the robustness and performance of the ATLAS tracking system, given the higher instantaneous and integrated luminosities realised following the shutdown. Because of the extreme radiation and collision rate environment, several new radiation-tolerant sensor and electronic technologies were utilised for this layer. This paper reports on the IBL construction and integration prior to its operation in the ATLAS detector.

Electron reconstruction and identification in the ATLAS experiment using the 2015 and 2016 LHC proton-proton collision data at $\sqrt{s}$ = 13 TeV (2019, background): “The innermost part of the inner detector consists of a high-granularity silicon pixel detector and includes the insertable B-layer [6, 7], a new tracking layer closest to the beamline designed to improve impact parameter resolution, which is important primarily for heavy-flavour identification.”
Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in $\sqrt{s}=13$ TeV $pp$ collisions using the ATLAS detector (2019, background): “During the first LHC long shutdown, a new tracking layer, known as the Insertable B-Layer [34,35], was added with an average sensor radius of 33 mm from the beam pipe to improve tracking and b-tagging performance.”
Luminosity determination in $pp$ collisions at $\sqrt{s}=13$ TeV using the ATLAS detector at the LHC (2022, background): “The measurement was derived from randomly sampled colliding-bunch crossings, where only the data from the silicon tracking detectors (i.e. the SCT and pixel detectors, including a new innermost layer, the ‘insertable B-layer’ (IBL) [11, 12] added before Run 2) were read out, typically at 200 Hz duri”
Jet energy scale and resolution measured in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector (2020, background): “most space-point provided by the insertable B-layer that was installed before Run 2 [11,12].”
Study of the rare decays of Bs0 and B0 mesons into muon pairs using data collected during 2015 and 2016 with the ATLAS detector (2018, background): “[19] for details about the new innermost silicon pixel layer that was installed for Run 2.”
