  • Where and for how long will experimental data be stored?

    Experimental Data will be stored by Diamond for a minimum period of 30 days from the date of its creation.   Following this initial storage period, Diamond will create a single archive copy of the Experimental Data for long-term access.  If more resilient long-term storage is required, this is the Users’ responsibility.

  • Access to experimental data

    Diamond shall use reasonable endeavours to preserve the confidentiality of Experimental Data during the Embargo Period.


    After the Embargo Period, Diamond may make Experimental Data available on an open access basis under a CC-BY-4.0 licence.


    Any PI or PI's Establishment that wishes to extend the Embargo Period for an additional 12 months at a time shall be entitled to submit an advance written request to Diamond's User Office within 3 months of the end of the Embargo Period. The request should specify the reasons for the proposed extension and will be considered and decided upon at a meeting of Diamond' Executive.
