Main themes

 

The R&D on accelerators for high energy physics is organised around several future world-wide projects:

  1. Facilities providing proton beams with ultra-high intensities and energies, aiming at very large hadron colliders, and covering as well luminosity and energy upgrades of the LHC at CERN.
  2. Electron-positron linear colliders with energies ranging between 500 and 3000 GeV in the centre-of-mass system, using the technology of superconductive high gradient accelerator structures recently developed by the TESLA international collaboration, and aiming at exploiting as well the two-beam technique for obtaining ultra-high gradients at room temperature developed by the CLIC international collaboration.
  3. Facilities providing intense neutrino beams (see for example Nufact or β-beams), using both improvements to the existing methods based on intense proton beams, and the more novel techniques based on radioactive ion or muon beams.
  4. Facilities delivering very high luminosity for the study of  Flavor physics such as SuperB.

Critical R&D required to build facilities providing proton beams with high intensity and energy include in particular the development of very high field superconductive magnets.

 

Specific R&D required for electron-positron linear colliders has been outlined by the International Linear Collider Technical Review Committee (see the report) of ICFA. A ranking of R&D items has been provided, both globally and for the different technical solutions discussed, which serves as an input to ESGARD.
Included among the main R&D items are further improvements to the superconductive technology (aiming in particular at rationalising the preparation of components and transferring the competences to industrial partners in view of future large scale cost-effective production), development of large scale control systems (including GAN, the Global Accelerator Network), reliability and safety aspects, precision beam dynamics, diagnostics and controls, as well important tests of power extraction structures and of the drive beam generation in the two-beam warm-temperature technique.

Critical R&D required to build facilities providing intense neutrino beams include work on high intensity targets, improvements to horn designs and beam phase-space cooling methods for muon beams.
 

 

In addition, important aspects of the work are common to all projects:

  1. Accelerator physics, beam dynamics and multi-purpose/wide-band optical systems, including tools for design and modeling.
  2. Global parameter optimisation and tolerance studies, with standard methods for qualification and evaluation.
  3. Development of high resolution beam diagnostic instrumention, both intercepting and non-intercepting.
  4. Definition of common parameter databases and protocols.


In the case of the R&D required for electron-positron linear colliders, several of the R&D items are also highly relevant to the on-going development of ultra-high brilliance Free Electron Laser sources (FELs), in particular work on low emmittance photo-injectors, and important aspects of the superconductive technology and diagnostic systems.
 

 

Finally, two additional aspects are common to the projects, and are pursued actively within ESGARD:

  1. Training and educational programmes aiming at spreading and sharing the knowledge base in the community at large (including both academia and associated industrial partners), in view of strengthening and enhancing the community of accelerator physicists and engineers at the European level.
  2. Dissemination of the information and of the outcomes of the R&D in the scientific community at large, as well as outreach activities directed towards the society at large (particularly in high-schools and universities) to popularise the achievements in the field and help promote the attractiveness of scientific careers among young Europeans.
