Abstract:

There is considerable and continuously increasing scientific interest
in high power, short-pulse radiation in the THz and IR region. Already
in 2003 in USA the BESAC Subcommittee recognized the importance of
IR/VUV production and encouraged facilities to consider VUV/IR science
within the concept of the existing dedicated storage rings. Later a
proposal for a Coherent Infrared Center (CIRCE) that would produce THz
and far IR coherent synchrotron radiation was presented by the Lawrence
Berkeley National Laboratory at the ALS. In the last years many SR
facilities performed with success experiments with coherent synchrotron
radiation (CSR).
IKNO (Innovation and KNOwledge) is a proposal for a multi-user facility
based on an electron storage ring optimised for the generation of
coherent synchrotron radiation (CSR) in the THz frequency range, and of
broadband incoherent synchrotron radiation (SR) ranging from the IR to
the VUV. [F. Sannibale, A.Marcelli and P. Innocenzi, IKNO, a user facility
for coherent terahertz and UV synchrotron radiation, J. Synch. Rad. 15,
655 (2008).] It will operated in an ultra-stable CSR mode with photon flux
in the THz frequency region up to nine orders of magnitude higher than
in existing 3rd generation light sources. Simultaneously, broadband
incoherent SR up to VUV frequencies will be available at the beamline ports.
The main characteristics of the IKNO storage and its performance in terms
of CSR and incoherent SR will be presented.
