New LHC detector technology - Installing the ATLAS IBL

The video explains the structure and function of the pixel detector in the Atlas experiment, focusing on the newly added Insertable B-Layer (IBL). The IBL is the innermost layer, enhancing the detector's precision. The installation process involved significant international collaboration, with major contributions from the USA. The IBL's successful integration into the Atlas detector highlights the project's complexity and the collaborative effort required to achieve it.

Explain the international collaboration involved in the development of the IBL.
