With a baseline operating gradient of 31,5 MV/m at a Q-value of 1·1010 the superconducting nine-cell cavities for the ILC are a challenging milestone for SRF technologie. Worldwide intensive ILC R&D programs are underway or in the planning stage in the all three regions of America, Asia and Europe. This paper will give an overview of the main activities in superconducting RF (SRF) technology.

The unanimous ICFA decision to choose the TESLA “cold” technology as the basis for the International Linear Collider, ILC, gave a global impulse to the superconducting RF, SCRF, technology. The perspective of building large accelerators based on high gradient superconducting cavities poses a number of new problems in term of performance reproducibility, large scale manufacturing and cost containment. In parallel with the ongoing R&D on basics in labs and universities, new large regional SCRF infrastructures are being developed to qualify treatment, assembly procedures and ancillary integration in performing cryomodules. US at Fermilab and Asia at KEK are strongly investing in these facilities and also Europe is considering duplicating and adjourning at CERN the operational facility set up at DESY by the TESLA Collaboration. In this paper the ongoing global effort on SCRF through the development of large regional infrastructures is outlined together with their status and plans.

JINR actively participates in ILC project. JINR physicists are planning to take part in several fields of activity in ILC: works on photo injector prototype, participation in design and construction of cryomodules, laser metrology, etc. Moreover Joint Institute is full-member pretender for possible hosting of ILC in the region near Dubna. International intergovernmental status of JINR, comfortable location of site, well developed infrastructure, geological, climate and relief conditions may become powerful advantages of Dubna siting among other proposals of ILC location. All above mentioned topics are discussed in the presented report.

Precise, single shot measurement of the beam position with a sub-micrometer resolution is required for the next generation linear accelerators such as International Linear Collider (ILC) and X-ray Free Electron Laser (XFEL). As a pill-box cavity structure is sensitive to the transverse offset of the beam at the dipole-mode resonance, e.g., TM110-mode, a pill-box type cavity is a good candidate for the sub-micrometer beam position monitor (BPM). Test cavity BPM had been designed and tested in KEK successfully, and miscellaneous improvements for the final prototype fabrication and beam tests are performed in collaboration between KEK, SLAC and PAL. With the successful results of beam test in ATF, 41 cavity BPMs will be produced by PAL and installed in ATF2, which is an advanced beam-test line under construction as the extension of existing ATF for the beam studies on the final focus of the planned ILC program. Technical design considerations, fabrication and test results are described in this paper.

CLIC main linac accelerating structures have extremely demanding high-gradient, high-power and wakefield performance requirements. The research program which has been put into place to develop such structures, as well as recent experimental and technological results are described. The current understanding of the effects which both limit the ultimate accelerating gradient and fix the practical operating gradient is presented.

Towards a Multi TeV Linear Collider; Drive Beam Generation with CTF3

The 3 TeV compact linear collider, CLIC, foresees an RF source based on a high current drive beam running parallel with the main linac. To generate this drive beam of very high instantaneous power a sophisticated complex consisting of a fully beam-loaded linac and several stages of beam compression is used. Although this scheme is very promising in terms of cost and power efficiency, it needs demonstration in a scaled version before construction of CLIC can be envisaged. This is the aim of the CLIC Test Facility CTF3, build by an international collaboration. CTF3 is constructed and exploited in several phases. Here we report present status, experimental achievements and future plans for CTF3.
