CERN hosts the largest accelerator complex in the world. The flagship machine is the LHC providing proton and heavy ion collisions at the energy frontier to 4 main experiments and a number of smaller ones. In addition, the LHC injector complex provides beams at a variety of energies and particle types to a number of experimental areas serving many fixed-target experiments together forming the CERN physics diversity programme. After a short recap of the history of LHC run 2, the status of the presently approved programme will be outlined. This includes the major upgrades to both the LHC and the injector complex as well as a number of upgraded, or new facilities coming online after the present long shutdown.
The European Particle Physics Strategy Update (EPPSU) is presently in progress to determine the priorities for the field in Europe during the coming years. As part of the input to this process, CERN has provided details of a number of projects that could be realized at CERN. These include studies for the next energy frontier machine as well as a number of possible facilities to enhance the diversity physics programme. The major studies for CLIC and FCC will be presented as well as a few of the other projects where significant additional infrastructure or enhancements to the complex are needed to realize them. It is hoped that the EPPSU will set the direction for taking some of the proposals forward within the constraints of the available resources of the organization.
