Scope and content
Under the microscope you can see a pixel of silicon from a new generation of high-precision detectors under development for ALICE. The ALICE detector is designed for the periods when the LHC collides the nuclei of lead atoms rather than protons. These lead collisions produce extremely dense tangles of particle tracks and many short-lived particles. Precision is key! The new silicon detectors are extremely thin and can measure the passage of particles with a precision of 5 thousandth’s of a millimetre. The connections to the electronics are integrated into the silicon.
