The next Inside Diamond open day will feature stalls and activities, a short introduction to Diamond and a tour of the machine. We expect the visit will last around two and a half hours. Booking for open days opens 6-8 weeks in advance of the event. Click here for more details.

To make the most effective use of beam time when performing tomography experiments, it is useful to be able to see the reconstructions of previous experiments as quickly as possible.
This is being achieved at diamond using a mix of dedicated hardware and software specifically put together to allow for fast reconstruction and visualisation of the very large datasets collected on the I12 JEEP beamline. The main points which were overcome in this work are the vast sizes of the collected and reconstructed data, which can be as much as 120GB of collected data and 80GB of reconstructed data for a single experiment, and the time constrains meaning that the reconstructed data should be available to the users for visualisation as soon as possible. To accomplish this the reconstruction pipeline is started during the data collection, where the images are transformed into sinograms as soon as the arrive from the camera. The next step of the process is to reconstruct the data which is done in two stages, the first produces a thumbnail reconstruction which is used for initial analysis and visualisation, and then the second step reconstructs at the full resolution. The reconstructions take place on a dedicated cluster of 8 machines, with 16GPS's available, which allows the reconstructions to be completed in around 2 minutes for the thumbnail reconstruction and 30 minutes for the full resolution reconstruction. Finally visualisation is available through a single workstation which has the capabilities to perform analysis tasks as well as visualise the data on a large 3D screen for ease of visualisation
