FAQ

  • How do I run the data acquisition GUI?

    Open a terminal window,

    type "gdalog"  - opens a log window

    type "gdaservers" - starts the servers wait until s"server initialisation complete" comes up in the log window

    type "gdaclient" the client should start.

  • Who do I call for help outside office hours?

    After 5.30pm call the Experimental Hall Coordinators on 8787. If they can fix the problem, they will. If not, they will call someone who can.

  • Can I go in the hutch? The ‘Beam On’ sign is lit.

    The red ‘Beam On’ sign means the hutch is searched and locked, and so there could be x-rays in the hutch. If you have closed the experimental shutter, you can press the Open Hutch button, and the door will unlock.

  • 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. 

  • What’s that really loud alarm?


    That’s the oxygen depletion alarm; it’s controlled by the large box on the wall near the hutch door. Call the Experimental Hall Coordinators on 8787.

  • Where did the beam go?

    You can see the beam status on the monitor near the ceiling.  The GDA software should automatically stop your data collection if the beam goes, and the scans should restart when it comes back. 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 anymore than a day of beamltime and may insist on this for periods over 48 hours to ensure that the facility is used efficiently. 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 and at weekends  please call 8787.
