The Stanford Synchrotron Radiation Lightsource (SSRL) is one of the pioneering synchrotron facilities in the world, known for outstanding user support, training future generations and important contributions to science and instrumentation. SSRL is an Office of Science User Facility operated for the U.S. Department of Energy by Stanford University.
The program of construction and commissioning through user experiments of the FEL source FERMI, the only FEL user facility in the world currently exploiting external seeding to offer intensity, wavelength and line width stability, achieved all of its intended targets in 2017.
Taiwan Light Source (TLS, 1.5 GeV) and Taiwan Photon Source (TPS, 3.0 GeV) are the two synchrotron light sources currently operated by the National Synchrotron Radiation Research Center (NSRRC). There are around 13,000 academic user visits to NSRRC every year; approximately 10% are international.
Additive manufacturing (AM, also known as 3D printing) allows us to create incredibly complex shapes, which would not be possible using traditional manufacturing techniques. However, objects created using AM have different properties from traditional manufacturing routes, which is sometimes a disadvantage.
Laser additive manufacturing (LAM) uses a laser to fuse together metallic, ceramic or other powders into complex 3D shapes, layer by layer. The cooling rates are extremely rapid, and since they are unlike conventional processes we don’t know the optimal conditions to obtain the best properties, delaying the uptake of LAM in the production of safety-critical engineering structures, such as turbine blades, energy storage and biomedical devices. We need a method to see inside the process of LAM to better understand and optimise the laser-matter interaction and powder consolidation mechanisms.
Based in the Research Complex at Harwell, a team of researchers have worked with scientists at I12, the Joint Engineering Environment Processing (JEEP) beamline and the Central Laser Facility to build a laser additive manufacturing machine which operates on a beamline, allowing you to see into the heart of the process, revealing the underlying physical phenomena during LAM.
