• Who do I call for help outside office hours?

    After 6pm (or 1pm on weekends), call the Experimental Hall Coordinators on 8787. If they can fix the problem, they will. If not, they will call someone who can.

  • Help! The GDA isn’t responding.

    Try restarting the GUI: see above (if you can’t close it, use the xkill command to do so). If that doesn’t work, you could try restarting the GDA servers. This takes a few minutes. Close the GUI, then double click the icon marked ‘Restart GDA Server’.

  • What’s that really loud alarm?

    That’s the either the oxygen depletion, explosive gas or toxic gas alarm; leave the area immediately and call the Experimental Hall Coordinators on 8787.

  • How do I get the oxygen level back up?

    The Experimental Hall Coordinators will let you unlock the hutch, and then open the double doors and the fire exit doors. Once the oxygen level rises above 19% you may re-enter the hutch.

  • Can I replace an empty gas bottle?

    NO! Please call the Experimental Hall Coordinators on 8787.

  • Where did the beam go?

    You can find the beam status by clicking the icon marked "Beam Status". The GDA software should automatically stop your data collection if the beam goes, but you may have to redo some scans. You can begin using the beam again when the "Port" shutter light goes green.

  • Can I work here alone?

    Yes, although we recommend that a minimum of 2 people are required for a shift. The Experimental Hall Coordinators (8787) must be informed when somebody is working on their own.

  • How do I acknowledge Diamond beamlines in publications?

    See this page for guidance.

  • What if my question isn’t answered here?

    This is only a FAQ, so use the menus at the top to find more information. Alternatively, ring your local contact: their number is probably on the beamline whiteboard. After 6pm (1pm on weekends) please call 8787.
