Indirizzo
Forma di lavoroTo take full advantage of the complementarity and modularity of soft/tender X-ray imaging techniques, plans are underway for the realization of a new Coherent Diffraction Imaging (CDI) beamline with multimodal capabilities in the energy range 350-4000 eV. The beamline and its experimental station have been designed to address a broad spectrum of scientific cases by performing soft/tender X-ray scattering and imaging experiments in different modes and geometries on a rich variety of samples; as such, it will represent a unique experimental facility worldwide, providing enhanced capabilities for Bragg ptychography, diffractive imaging, Fourier transform holography, scanning X-ray nanodiffraction and X-ray photon correlation spectroscopy.
The experimental station, currently under construction, is based on a fully UHV-compatible diffractometer. Within the vacuum chamber, a robust support platform will precisely position the optics, ensuring optimal alignment relative to the sample. Scanning nanoactuators will be used to position the pinholes and the set-up comprising the zone plate and order-sorting aperture. A liquid-helium cooled sample manipulator will enable access to the most intruguing phases of novel superconductros and electronic materials. The high-efficiency, fast X-ray detectors (both pixelated and area-integrating) installed on the moveable diffraction arms will provide both time-domain access for the investigation of collective ordering dynamics as well as off-scattering plane angular capabilities.
The successful candidate will be engaged in the development and operation of the CDI beamline at Elettra 2.0. Specifically, he/she will oversee all aspects of testing and commissioning of the new experimental station, from conducting factory acceptance tests to supervising its installation. This responsibility includes evaluating the overall performance of the experimental apparatus in collaboration with physicists and engineers of the optics, mechanics, vacuum gruop, detector laboratories and ICT staff. Moreover, the envisaged role requires a proactive approach to supporting the future users and collaborators of the CDI beamline through every phase of their activity, from preparing the experimental set-up to conducting complex data analysis and writing scientific manuscripts.
In order to gain high-level skills in Coherent Diffraction Imaging with state-of-the-art soft x-ray scattering and imaging tools, the successful candidate will be required to spend a working period of 12 months at the Coherent Soft X-ray Scattering (CSX) beamline of the NSLS-II synchrotron radiation facility at the Brookhaven National Laboratory (USA). See:
https://www.bnl.gov/nsls2/beamlines/beamline.php?r=23-ID-1 for more information.
For logistic reasons a driving license valid for the USA - such as an Italian driving license optionally accompanied by an international driving license - is required. After this initial training period, he/she will return at Elettra Sincrotrone Trieste to contribute to the development and commission the CDI beamline.
