New experimental setups

Some of the most important laser facilities in Europe generating ultrashort pulses are involved in the XLIC Action. Some examples are:

– IFN and Politecnico de Milano (IT) (F. Calegari and M. Nisoli)
– ICFO Barcelona (ES) (J. Bigert)
– CELIA Bordeaux (FR) (Y. Mairesse)
– Eurpean XFEL Hamburg (DE) (M. Meyer)
– EPFL Laussane (CH) (M. Chergui)
– Imperial Collegue (UK) (J. Marangos)

Collaborations among experimental groups are leading to new experimental setups. Some examples of these collaborations are:

  • Collaboration between the group of CNR-IFN Milano, Politecnico de Milano and ISMO Orsay. The Velocity Map Imaging (VMI) method that allows to measure the mass spectrum and the momentum distribution of the produced photo-fragments as a function of the delay between the XUV pump and the probe pulses (VIS-IR) has been coupled with a source of gas-phase biomolecules similar to the ones used in ISMO. See https://xlic.qui.uam.es/?p=1667
  • Collaboration between Milano and Barcelona to achieve the temporal characterization of attosecond pulses generated by mid-IR pulses using the techniques available at ICFO. See https://xlic.qui.uam.es/?p=1513
  • J. Greewood, at the Ultrafast Belfast Group, QUB (UK), has built and tested a chiral spectrometer. This was a collaboration with Jacinto Sa at Uppsala University. The instrument is a conventional time of flight mass spectrometer augmented with stereo-electron detection so that the photoelectron circular dichroism of samples can be measured which allows the enantiomeric excess of chiral samples to be determined. A paper describing this instrument is currently under consideration by Analytica Chimica Acta.
  • A new facility, Andromède, isavailable at Orsay for molecular and cluster production and acceleration at high velocity since a few months (Serge Della Negra, to be published). The AGAT set up has been displaced to this facility for studies of small highly hydrogenated carbon based molecules fragmentation. Experiments have been confronted with theoretical results predicted by the group of Manuel Alcamí at UAM.
  • Calegari, at CNR-IFN (IT), has developed a new source for the generation of bio-relevant molecules in gas-phase. The source has been realized in collaboration with Dr. Raluca Cireasa (Institut des Sciences Moléculaires d’Orsay, Orsay – France). For adittional information, you may see J. Phys. Conf. Ser., vol. 635, p. 112131, 2015; and the STSM http://xlic.qui.uam.es/?p=1667
  • Construction of an apparatus for gas phase study and soft –landing applications of large biomolecular ion species (CNR-ISM, Montelibretti), Roma. The development of the apparatus is based on a strong collaboration of the CNR-ISM (Rome) group with Dr. Steen Brøndsted Nielsen (Aarhus University, Aarhus, Denmark) and Dr. Patrick Rousseau and Alicja Domaracka (CIMAP-GANIL, Caen, France)
