To see a list of available software, type:

module avail

To load the correct environment for the software, type:

module load <modulename> e.g. module load chooch

Then run the program as usual, e.g. chooch -e Se -a K scan1.dat

You can find the beam status by visiting machine-status.diamond.ac.uk. The GDA software will not start new data collections if the beam is down, but you may have some blank images if the beam dropped during a data collection. You can begin using the beam again when the "Port Shutter", "Optics Shutter" and "Experimental Shutters" are all shown as Open.

See this page for guidance.

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.

If you have a local contact, and have their office number, and it is during working hours (9am-5pm London time), you can call them directly. If not, please call the Experimental Hall Coordinators on 8787. If they can fix the problem, they will. If not, they will call someone who can.

This is only a FAQ, so use the menus at the top to find more information, or email your local contact.
