BeamLine description

GasPhase Beamline - BL instrumentations & infos

Differently from most other beamlines at ELETTRA, there is not a permanent end station at GasPhase. Our beamline is presently equipped with many distinct interchangeable apparatuses, listed below. Any apparatus is available to Users for their proposals, the choice of the end station depending on experimental requirements.

Moreover Users can bring their own apparatus to perform experiments, provided that it is compatible with beamline requirements (please contact beamline staff to check).

photoemission experiments on aggressive molecular species (radicals, transients, reactive species)

1. VG-220i set up for photoemission experiments on condensable vapours, also equipped for TOF mass spectrometry
2. Multi-coincidence experiments set up, for angle resolved and electron-electron coincidence experiments in a versatile multichannel configuration.
3. Molecular beam set up, for PEPICo mass spectroscopy
4. Velocity Map Imaging (VMI) 
5. PIFS, Photon Induced Fluorescence Spectroscopy (UV-Vis dispersed fluorescence with Minuteman 305V Czerny-Turner 0,5 m Spectrometer) 
6. ARPES, angle-resolved photoemission experiments on aggressive molecular species (radicals, transients, reactive species)
7. Two colors experiments SR + IR laser beam.
8. Absolute absorption cross section cell 

Two colors experiments SR + IR laser beam can be performed with set up 1 to 5 on the low energy branch line.

1.  SES200-ULLA, for high resolution photoemission of molecular vapours (LTP 20115157, prof. Carla Puglia, University of Uppsala, Sweden) [doi: 10.1063/1.4907723];
2. PIFS+ "XUV-PIK”, for dispersed emission experiments with a compact XUV spectrometer (LTP 20130233, dr. Luca Poletto, IFN-CNR, Padua, Italy) [doi: 10.1063/1.4898315];
3. “CESyRa”, for photoionization  of clusters of refractory materials, via electron-ion multicoincidence detection. (LTP 20170487; prof. Paolo Piseri, CIMAINA, University of Milan, Italy [on going upgrade; doi: 10.1016/j.elspec.2008.05.003]

Moreover each user can bring his own apparatus to perform experiments, provided that it is compatible with the beamline requirements (please contact beamline staff to check).
