The conservation and restoration of cultural property focuses on protection and care of cultural property, including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars.
A synchrotron light source is a source of electromagnetic radiation (EM) usually produced by a storage ring, for scientific and technical purposes. First observed in synchrotrons, synchrotron light is now produced by storage rings and other specialized particle accelerators, typically accelerating electrons. Once the high-energy electron beam has been generated, it is directed into auxiliary components such as bending magnets and insertion devices in storage rings and free electron lasers. These supply the strong magnetic fields perpendicular to the beam that are needed to stimulate the high energy electrons to emit photons.

With respect to cultural property, conservation science is the interdisciplinary study of the conservation of art, architecture, technical art history and other cultural works through the use of scientific inquiry. General areas of research include the technology and structure of artistic and historic works. In other words, the materials and techniques from which cultural, artistic and historic objects are made. There are three broad categories of conservation science with respect to cultural heritage: understanding the materials and techniques used by artists, study of the causes of deterioration, and improving techniques and materials for examination and treatment. Conservation science includes aspects of materials science, chemistry, physics, biology, and engineering, as well as art history and anthropology. Institutions such as the Getty Conservation Institute specialize in publishing and disseminating information relating to both tools used for and outcomes of conservation science research, as well as recent discoveries in the field.

The Prussian Cultural Heritage Foundation is a German federal government body that oversees 27 museums and cultural organizations in and around Berlin, Germany. Its purview includes all of Berlin's State Museums, the Berlin State Library, the Prussian Privy State Archives and a variety of institutes and research centers. As such, it is one of the largest cultural organizations in the world, and also the largest cultural employer in Germany with around 2,000 staff as of 2020. More than four million people visited its museums in 2019.
The Staatliche Museen zu Berlin are a group of institutions in Berlin, Germany, comprising seventeen museums in five clusters; several research institutes; libraries; and supporting facilities. They are overseen by the Prussian Cultural Heritage Foundation and funded by the German federal government in collaboration with Germany's federal states. The central complex on Museum Island was added to the UNESCO list of World Heritage Sites in 1999. By 2007, the Staatliche Museen zu Berlin had grown into the largest complex of museums in Europe. The museum was originally founded by King Friedrich Wilhelm III of Prussia in 1823 as the Königliche Museen.
The Getty Conservation Institute (GCI), located in Los Angeles, California, is a program of the J. Paul Getty Trust. It is headquartered at the Getty Center but also has facilities at the Getty Villa, and commenced operation in 1985. The GCI is a private international research institution dedicated to advancing conservation practice through the creation and delivery of knowledge. It "serves the conservation community through scientific research, education and training, model field projects, and the dissemination of the results of both its own work and the work of others in the field" and "adheres to the principles that guide the work of the Getty Trust: service, philanthropy, teaching, and access." GCI has activities in both art conservation and architectural conservation.
Friedrich Wilhelm Rathgen was a German chemist and a founder of the field of conservation science.
Micro x-ray fluorescence (μXRF) is an elemental analysis technique that relies on the same principles as x-ray fluorescence (XRF). Synchrotron X-rays may be used to provide elemental imaging with biological samples. The spatial resolution diameter of micro x-ray fluorescence is many orders of magnitude smaller than that of conventional XRF. While a smaller excitation spot can be achieved by restricting x-ray beam using a pinhole aperture, this method blocks much of the x-ray flux which has an adverse effect on the sensitivity of trace elemental analysis. Two types of x-ray optics, polycapillary and doubly curved crystal focusing optics, are able to create small focal spots of just a few micrometers in diameter. By using x-ray optics, the irradiation of the focal spot is much more intense and allows for enhanced trace element analysis and better resolution of small features. Micro x-ray fluorescence using x-ray optics has been used in applications such as forensics, small feature evaluations, elemental mapping, mineralogy, electronics, multi-layered coating analysis, micro-contamination detection, film and plating thickness, biology and environment.

For the majority of the Smithsonian collections, MCI is the only Smithsonian resource for technical studies and analyses.
Conservation and restoration of metals is the activity devoted to the protection and preservation of historical and archaeological objects made partly or entirely of metal. In it are included all activities aimed at preventing or slowing deterioration of items, as well as improving accessibility and readability of the objects of cultural heritage. Despite the fact that metals are generally considered as relatively permanent and stable materials, in contact with the environment they deteriorate gradually, some faster and some much slower. This applies especially to archaeological finds.
A conservation scientist is a museum professional who works in the field of conservation science and whose focus is on the research of cultural heritage through scientific inquiry. Conservation scientists conduct applied scientific research and techniques to determine the material, chemical, and technical aspects of cultural heritage. The technical information conservation scientists gather is then used by conservator and curators to decide the most suitable conservation treatments for the examined object and/or adds to our knowledge about the object by providing answers about the material composition, fabrication, authenticity, and previous restoration treatments.
French national institute of cultural heritage, called Institut national du patrimoine (Inp), is the only academy in France in charge of the training of both curators and conservators. It belongs to French Ministry of Culture and is organized in 2 departments.
SEM-XRF is an established technical term for adding a X-ray generator to a Scanning Electron Microscope (SEM). Technological progress in the fields of small-spot low-power X-ray tubes and of polycapillary X-ray optics has enabled the development of compact micro-focus X-ray sources that can be attached to a SEM equipped for energy-dispersive X-ray spectroscopy.
