LIU: LHC Injectors Upgrade
LIU plans to reliably deliver the beams required to reach the goals of the HL-LHC. This includes LINAC4, the PS booster, the PS, the SPS, as well as the heavy ion chain.

FCC: Future Circular Collider
The Future Circular Collider (FCC) design study explores options for accelerator projects in a global context, with emphasis on proton-proton and electron-positron high-energy frontier machines. These design studies are coupled to a vigorous accelerator R&D programme, including high-field magnets and high-gradient accelerating structures, in collaboration with national institutes, laboratories and universities worldwide.

ARIES: Accelerator Research And Innovation For European Science And Society
ARIES is an Integrating Activity project which aims to develop European particle accelerator infrastructures, co-funded under the European Commission's Horizon 2020 Research and Innovation programme. Over four years, ARIES will work towards improving the performance, availability, and sustainability of particle accelerators, transferring the benefits and applications of accelerator technology to both science and society, and enlarging and integrating the European accelerator community.  

QUACO: Quadrupole Corrector
The QUACO project is a part of the IR magnets in HL-LHC. Its objective is the production of the first two "First-of-a-kind" HL-LHC "two-in-one quadrupoles magnets".  

TIARA: Test Infrastructure and Accelerator Research Area
The main objective of TIARA is the integration of national and international accelerator R&D infrastructures into a single distributed European accelerator R&D facility. This will include the implementation of organisational structures to combine existing individual infrastructures, ensuring their efficient operation and upgrades, and the construction of new infrastructures as part of TIARA.

EuCARD: European Coordination for Accelerator Research & Development
EuCARD was a common venture of 37 European Accelerator Laboratories, Institutes, Universities, and Industrial Partners involved in accelerator sciences and technologies. The project, initiated by ESGARD, was an Integrating Activity co-funded by the European Commission under Framework Programme 7 for a duration of four years, starting April 1st, 2009.  

EuCARD-2: Enhanced European Coordination for Accelerator Research & Development
EuCARD-2 contributed to positioning European accelerator infrastructures at the forefront of global research, by building the next generation of particle accelerators. EuCARD-2 explored ways to develop smaller, more powerful, efficient, and smarter accelerators for the benefit of both science and society.  

HiLumi LHC Design Study: High Luminosity Large Hadron Collider Design Study
HiLumi LHC was an FP7 Design Study and part of an overall project that aimed to federate efforts and R&D of a large community towards the ambitious HL-LHC objectives. HiLumi LHC involved participants from outside the European Research Area (ERA), in particular leading US and Japanese laboratories, which facilitated the implementation of the construction phase as a global project.  

sLHC: super LHC
The sLHC project (super LHC) aimed for a tenfold increase in luminosity for 14 TeV proton–proton collisions, which was to be achieved through the successive implementation of several new elements and technical improvements from 2013–2018. These included the major replacement of several accelerators in the LHC proton-injector chain, upgrades of the LHC interaction regions and enhancements to the general-purpose experiments ATLAS and CMS. The accelerator part of the sLHC project consisted of a set of sub-projects that fell into three categories: sLHC construction projects, sLHC project preparation studies and an sLHC luminosity upgrade network.  

LARP: U.S. LHC Accelerator Research Program
LARP consists of four US laboratories: BNL, FNAL, LBNL, SLAC, who collaborate with CERN in the context of HL-LHC on the Large Hadron Collider to increase luminosity in the interaction regions and to use, develop, and preserve unique U.S. resources and capabilities.
