Scientific Activities

Experiments at CERN

The current experimental programme at CERN is summarized in the electronic version of the Grey Book database.

The experiments listed there use one of the following machines: the Large Hadron Collider (LHC), with energy up to 14 TeV, the most powerful accelerator in the world; the 400 GeV Super Proton Synchrotron (SPS), which now acts as an injector for the LHC, but also hosts fixed-target experiments and provides test beams; the 28 GeV Proton Synchrotron (PS), including the Antiproton Decelerator (AD) for slow antiprotons and the ISOLDE facility for short-lived ions. R&D projects aim at developing new detector technologies and data acquisition systems for the LHC experiments are also listed.

In addition there are Recognized Experiments that complement CERN's scientific programme, typically in astrophysics or non-accelerator experiments. A recent addition to the programme is the Neutrino Platform, which hosts R&D on detectors for future neutrino experiments around the world. Studies are also in progress for physics at possible future accelerators beyond the LHC, such as CLIC and FCC.

Activities in EP

The participation in the major LHC experiments is organized in groups for ATLAS, CMS, LHCb and ALICE.  The participation in non-LHC experiments is coordinated via the Small and Medium Experiments (SME) team, which includes direct participation in NA62, COMPASS, the AD experiments, ISOLDE, CAST and CLOUD. The Linear Collider Detector (LCD) group studies physics and detectors for future accelerators, including synergy with the FCC.  A group is being set up to act as a focal point for neutrino physics. 

A significant aspect of the scientific work in EP involves the development and installation of detectors, their readout electronics, and the software to exploit them for physics. Support groups for Detector Technologies (DT), Electronic Systems for Experiments (ESE) and Software Design for Experiments (SFT) provide support to the scientific activities across the experimental programme.
