New LHC detector technology - Engineering the ATLAS IBL

The video tutorial provides an overview of the Insertable B-Layer (IBL) at CERN's Atlas experiment. It explains the IBL's function as a particle detector, its structure composed of staves, and the innovative use of 3D sensors. The tutorial highlights the differences between planar and 3D sensors, emphasizing the latter's robustness in harsh radiation environments. It concludes with the installation and testing process of the IBL, ensuring all systems are operational before data recording begins.

What is the primary function of the sensors in the IBL?

• To provide power to the detector

• To detect particles instead of light

• To cool down the system

• To capture images of particles

What is the main difference between planar and 3D sensors in the IBL?

• Planar sensors are a new technology

• 3D sensors have vertically embedded electrodes

• 3D sensors have horizontally arranged electrodes

• Planar sensors are more robust against radiation

What is the purpose of the carbon support structure in the IBL?

• To provide cooling to the sensors

• To support the sensors and chips

• To power the sensors

• To detect particles

What is the next step after installing the IBL?

• Connecting and testing all systems

• Starting data recording immediately

• Handing it over to the operations team

• Reworking the sensors

What indicates the success of the IBL installation from the team's perspective?

• Installation of more sensors

• Completion of all tests and checklists

• Immediate data recording

• Reduction in radiation levels
