Cím: The Low Density Matter Beamline at the Italian Free Electron Laser FERMI

Időpont: 2015. szeptember 18. 9 óra
Helyszín: Szeged, Tisza Lajos krt. 85-87.

In this talk the current status and recent results of the Low Density Matter
(LDM) beamline at the FERMI Free Electron Laser in Trieste, Italy will be
presented.

Free Electron Lasers fulfill the need for soft and hard X-ray radiation with
extremely high brilliance, a high degree of (transverse and longitudinal)
coherence, and duration in the femtosecond time domain. FERMI covers the
spectral range from 100 down to 4 nm and has been designed as a Users’
facility providing stable operation, high spectral purity, full tunability,
variable polarization, and low timing jitter. Since the beginning of Users’
operation in December 2012, FERMI has received ~200 proposals, and allocated
~1/3 of them. Three beamlines are open to users (Diffraction and Projection
Imaging; Elastic and Inelastic Scattering-TIMEX; Low Density Matter) and three
more are scheduled to open in 2016.

The LDM beamline caters to the atomic-, molecular-, and cluster-physics
community, offering an endstation for photoelectron, photoion, and photon-
scattering spectroscopy of supersonic jets (notably, of helium droplets, which
can be used to transport and cool large molecules). Beyond its standard
spectrometers (Velocity Map Imaging; ion Time of Flight; photon scattering)
the end-station has accommodated user-supplied instruments, for Users’
experiments as well as FERMI characterization experiments.
