The East Area is one of CERNs experimental area, running since its foundation in 1958. Extracting a 24GeV proton beam from the Proton Synchrotron accelerator, the primary beam is divided into different secondary beams, serving various experiments and user’s facilities such as CLOUD, CHARM, IRRAD.

/CERN East Area Renovation project team
The East Area at the Proton Synchrotron is one of the intensely used facilities at CERN, serving for over 56 years beams nowadays to more than 20 user teams and experiments for about 200 days of running each year. Besides primary proton and ion beams for the irradiation facilities IRRAD and CHARM, mixed secondary beams of hadrons, electrons and muons within a range of 0.5 GeV/c to 12 GeV/c are provided. [...]

Study of the energy savings resulting from the East Area renovation

CERN’s East Experimental Area, situated on the Swiss side of the Meyrin site, with its four beamlines, has served physics for more than 40 years. As the building and equipment are reaching their end of life, a thorough consolidation project has been initiated in order to provide many more years of reliable operation. [...]

The East Area at CERN’s Proton Synchrotron delivers since over 56 years primary proton and ion beams as well as mixed secondary beams of hadrons, electrons and muons in a range of 0.5 GeV/c to 12 GeV/c. The CERN Management approved in 2016 a full renovation of this intensively used facility. [...]

How to Manage a Large Scale Beam Line Consolidation in a Highly Activated Area?
/ Evrard, Sebastien (CERN) ; Grenard, Jean-Louis (CERN) ; Harrouch, Erwan (CERN) ; Herve, Angelito (CERN) ; Pardons, Ans (CERN) ; Pira, Yann (CERN) ; Seraphin, Yann (CERN) ; Theis, Christian (CERN) ; Vincke, Helmut (CERN)
The TDC2/TCC2 consolidation is a good example showing how the complexity of interventions in high radiation areas has increased over the last five years. Due to its duration, its dispersion, the diversity of the teams involved, the fixed deadlines, the risks and external constraints, this worksite prefigures large scale-interventions in the LHC during long shutdown 2 (LS2) and even more LS3. [...]

Optimising Machine-Experiment Interventions in HL-LHC
/ Sanchez Galan, Francisco (CERN) ; Adorisio, Cristina (CERN) ; Bergstrom, Ida (CERN) ; Brethoux, Damien (CERN) ; Evrard, Sebastien (CERN) ; Gaddi, Andrea (CERN) ; Krzkempek, Lukasz (CERN) ; Lazzaroni, Michael (CERN) ; Perez Espinos, Jaime (CERN) ; Raymond, Michel (CERN) et al.
The luminosity reach of the HL-LHC experiments implies new constraints for the protection of the inner triplets from the machine debris. In general activation levels will increase a factor of 15-30 from the 2015 values (LS1), affecting both radiation tolerance of equipment and maintenance scenarios. [...]

Mechanical Consolidation of the LHC Inner Triplet Magnet Supporting System for Remote Alignment
/ Micolon, Frederic (CERN) ; Bourcey, Nicolas (CERN) ; Deschamps, Jean-Baptiste (CERN) ; Herty, Andreas (CERN) ; Le Naour, Sandrine (CERN) ; Mikkola, Tommi (CERN) ; Parma, Vittorio (CERN) ; Ramos, Delio (CERN) ; Rude, Vivien (CERN) ; Sosin, Mateusz (CERN)
Given the high radiation area and the tight alignment tolerances, the LHC inner triplet magnets were designed to be realigned remotely using motorized supporting jacks. However, during run 2 the LHC triplet realignment system started to show an unexpected behavior with erratic load variations on the magnet supporting jacks when operated [...]
