Description
The I12 Joint Engineering, Environmental and Processing (JEEP) beamline, was constructed during Phase II of the Diamond Light Source. The beamline started operating in November 2009. It is located on a short (5 m) straight section of the 3 GeV Diamond storage ring. The insertion device is a 4.2 T superconducting multipole wiggler. User experiments are possible with filtered white beam or monochromatic X-rays in the energy range 53-150 keV from a bent Laue monochromator. The beam energy enables good penetration through large or dense samples, combined with a large beam size from the wiggler fan (1 mrad horizontally × 0.3 mrad vertically). These beam characteristics permit the study of materials and processes inside environmental chambers and on sample sizes that are more representative of bulk materials. X-ray techniques available are radiography, tomography, energy-dispersive diffraction and monochromatic 2D diffraction/scattering. I12 has established a broad user community in materials science and processing, chemical processing, biomedical engineering, civil engineering, environmental science, palaeontology and physics. The majority of experiments are time resolved, in-situ studies, often involving processing equipment brought by users
