XRD1

Welcome to XRD1 @ Elettra.

X-rays are an invaluable probe of the structure of matter, and the range of problems where X-rays have proved to be decisive in unravelling a material structure is very wide. Exploiting the wide spectrum offered by a powerful multipole wiggler, the XRD1 beamline offers the possibility to structurally characterize matter at many different levels, having a broad applications in science and technology.
X-ray diffraction can provide an atomic-detail, three-dimensional structure of small and large molecules, playing a pivotal role in synthetic chemistry and offering the basis to understand the response of a molecular structure to an external influence such as the variation of pressure, temperature or humidity, electric or magnetic fields, photo-excitation, and so on.
At higher level, X-ray diffraction can characterize matter according to the spatial arrangement of the molecules in solid state, justifying macroscopic properties of materials and opening to an infinity of technological opportunities. All these impact everyone’s everyday life, spanning from pharmaceutical drugs efficacy and efficiency to energy production and storage, pollutant-capture materials and food industry.

User Area

Proposal Submission - Monthly based

For measurements not requiring particular setups, exploiting instruments already available at the beamline is possible to use a rapid allocation mechanism offering different advantages:
- no deadline: it is possible to submit a proposal at any time;
- proposal evaluation on a monthly basis;
- reduced dead-time between proposal submission and allocation;
- automatic re-submission in case of overbooking.
We strongly encourage XRD1 users to take advantage of this new procedure, available at the VUO page via the link “Monthly proposal”. It will be still possible to apply on a six-month basis if the experiment requires a particular setup in order to be performed or extended time is required for bureaucratic purposes such as VISA applications.

Proposal Submission - Other

For experiments not eligible to monthly access (for which a particular setup or long times issues, as VISA, are required), the standard six-month based procedure should be followed (look for the User Area in the quick links). The deadlines for proposal submission for beamtime allocation are aroud mid-March, for the period January 1st to June 30th, and mid-September, for the period July 1st to December 31th, at 4:30 pm (MET).
