The Experimental Risk Assessment (ERA) is the place to record and address any hazards that may arise from your experiment. It is critical to complete the ERA for all experiment types at Diamond. SamplesOne of the most common hazards for an experiment at Diamond is the samples themselves. Every sample that you bring to Diamond must be covered by one of the sample entries in the ERA. Your experiment might be to look at 10 samples of very similar composition with the same associated risks: in this case you need only submit one sample to the ERA.
EquipmentIf you’re bringing your own equipment to I15-1 (i.e. your own in situ environment) then you need to risk assess it here. Experimental MethodsHere you should specify all of the processes which are going to occur on the beamline during your experiment. For even the simplest experiment, you will still be mounting and unmounting samples from the beamline so you should describe here how that is going to be done, and any precautions you need to take. Lab AccessIf your experiment involves you coming to Diamond (i.e. it’s not an easy access experiment); you should request lab access. This is required for you work in our side labs, irrespective of how non-hazardous your samples are. Even if you are planning on loading your capillaries before you come to Diamond, you may need some lab space to reload capillaries in the event that one of them gets broken. |

It is important to characterise the samples for a PDF experiment as comprehensively as possible before your beamtime. The three key properties that are required are;
The sample composition, density and packing fraction are essential parameters that should be known as accurately as possible in order to perform the data reduction step and generate the PDFs. A range of suitable analysis methods should be performed such as XRF, TGA/DSC-MS etc. to characterise the sample in advance of the beamtime. Additional information such as amorphous content, concentration of impurity phases etc. will also be useful during analysis. Additional FactorsThere are additional factors that should be considered regarding the samples, such as:
