50 Years of RF Superconductivity
Hasan S. Padamsee (Cornell University)
Seminar Room 3, 15:00h
2011 is the 100th anniversary of Kammerlingh Onnes' discovery of
superconductivity. It is also the 50th anniversary of the launch of RF
superconductivity at Rutherford Appleton Laboratory in 1961. Exploration
of RF superconductivity took off at Stanford University in the early 1960's
with the acceleration of electrons in a lead-plated on copper resonator.
Steady advances in accelerating gradients have led to large-scale application
to electron, proton and ion accelerators around the world for research in
elementary particle, nuclear, and nuclear-astrophysics, high intensity x-ray
sources, free electron lasers, and neutron spallation sources. In all more
than one kilometer of cavities have provided more than 7GeV of acceleration.
The largest application underway today is a 15 GeV superconducting linac
for the European XFEL in Hamburg, Germany. A new Facility for Rare Isotope
Beams (FRIB) is under way at MSU in the US to allow the study of exotic
isotopes related to stellar evolution. A major future application is likely to be
the International Linear Collider (ILC). To achieve TeV energy will require 16 km
of superconducting cavities. The success of such applications has sprung
from the steady advances in performance of SRF. I will also discuss exciting
prospects for future advances.
