Latest Developments in Superconducting RF Structures
Superconducting RF technology is since
P. Kneisel (Jefferson Lab)
nearly a decade routinely applied to different
kinds of accelerating devices: linear accelerators,
storage rings, synchrotron light sources and FEL’s. With the technology recommendation for the International
Linear Collider (ILC) a year ago, new emphasis has been placed on improving the performance of accelerating cavities
both in Q-value and in accelerating gradients with the goal to achieve performance levels close to the fundamental
limits given by the material parameters of the choice material, niobium. This paper will summarize the challenges
to SRF technology and will review the latest developments in superconducting structure design. Additionally, it will
give an overview of the newest results and will report on the developments in alternative materials and technologies.
New Developments on RF Power Sources
The classical generation of RF power with
J. Jacob (ESRF)
klystrons and tetrodes is evolving and changing
to meet the demands of higher efficiency
and simpler maintenance. Developments of IOT tubes for FEL, Energy Recovery Linacs and Storage Rings, together
with solid state technology approaches and combination techniques for high power generation are opening new
alternatives to the classical ones. An overview of the new concepts, designs and solutions applied to the new accelerators
will be presented. Advantages and drawbacks of new versus classical technologies as well as strategies for the
selection will be discussed.
Digital Low Level RF
The demand on high stability and precision
M.-E. Angoletta (CERN)
on the RF voltage for modern accelerators, as
well as better diagnostics, maintenance and
flexibility is driving the community to develop Digital Low Level RF systems (DLLRF) for the new linear accelerators,
but also for synchrotrons. An overview of the state of the art in digital technologies applied to DLLRF systems and
an overview of the different designs developed or in development at the different labs will be presented.
