NFFA-Trieste is an open access facility to perform experiments in nanoscience that involve growth, nano-characterization and spectroscopy with synchrotron radiation, as well as dedicated DFT and simulation. NFFA-Trieste is the first Open Access Station entirely developed in the spirit of NFFA Design Study (FP7) that is to provide integrated services for nanoscience including growth (MBE, PLD, in-UHV depositions) characterization (LEED, MOKE, XPS, AES) and access to state-of-the-art fine analysis (Spin-ARPES, XMCD) at the APE-NFFA laboratory. The Open Access is regulated by an on-line proposal system and international peer-review that will consider NFFA specific projects that need integrated access to several relevant steps in the nanoscience research. An integrated data management and repository is in place for all NFFA-Trieste proposals and experiments. NFFA-Trieste is also accessible via NFFA-Europe H2020 Integrating Action.
