The High-Luminosity Large Hadron Collider (HL-LHC) project aims to crank up the performance of the LHC in order to increase the potential for discoveries after 2028. The objective is to increase luminosity by a factor of 10 beyond the LHC’s design value. The project is led by CERN with the support of an international collaboration of 44 institutions in 20 countries.
Luminosity is an important indicator of the performance of an accelerator: it is proportional to the number of collisions that occur in a given amount of time. The higher the luminosity, the more data the experiments can gather to allow them to observe rare processes.
The first pre-series cryomodule equipped with superconducting Radio Frequency Dipole (RFD) crab cavities was completed in October 2023 at Science and Technology Facilities Council (STFC)’s Daresbury Laboratory as a collaboration between HL-LHC-UK and CERN
Capable of better tracking the position of cold masses inside their cryostat, the new technique tested at Fermilab will equip all the HL-LHC's triplet quadrupoles and crab cavities.
The new metallic structure, installed in SM18, will be part of the IT String Test Stand. It will house the main components of the HL-LHC powering systems, due for arrival at the end of 2022
Crab cavities are critical to increase the number of interactions. After successful prototyping and testing, the US programme has entered series production.
