SYNAPSE: Brain Mapping Takes an International Dimension

2025

Teaching about non-deterministic physics: an almost forgotten fundamental contribution of Marie Curie

The first historical steps of radioactivity research offer an excellent opportunity to teach a key concept of modern physics: non-deterministic phenomena. However, this opportunity is often wasted because of historical misconceptions and of the irrational ...

Valence photoemission

Giorgio Margaritondo

The basic features of this family of techniques are discussed, beginning with its historical development. Angle-resolved (band mapping) and angle-integrated techniques are analyzed as well as a series of experimental approaches requiring powerful photon so ...

Semiconductors, general properties

Giorgio Margaritondo

This presentation starts with a general description of the electronic energy structure of insulators. This is the background of basic semiconductor features including the bands and the forbidden gap, the effective mass, the mobility and doping with donors ...

Teaching about the birth of synchrotron light: the role of Frascati and a missed opportunity

Giorgio Margaritondo

The users of synchrotron light are now tens of thousands throughout the world. Paradoxically, many of them do not know much about the early history of their domain. This is regrettable, since education about the initial developments makes it easier to full ...

Synchrotron radiation

Giorgio Margaritondo

Electron accelerators such as synchrotrons and storage rings are the best sources of X-rays and ultraviolet photons for research and technological applications. The physical mechanisms for all these sources use relativistic effects to increase the emission ...

SYNAPSE: An international roadmap to large brain imaging

Giorgio Margaritondo

Since 2020, synchrotron radiation facilities in several Asia-Pacific countries have been collaborating in a major project called "SYNAPSE"(Synchrotrons for Neuroscience: an Asia-Pacific Scientific Enterprise). They use x-ray imaging to attack in a coordina ...

Who were the founders of synchrotron radiation? Historical facts and misconceptions

Giorgio Margaritondo

Synchrotron radiation is now a gigantic worldwide enterprise involving tens of thousands of researchers. Quite famous in this field are the landmark accomplishments of illuminated pioneers like Dave Shirley. Somewhat less known, however, are the historical ...

High-resolution fast-tomography brain-imaging beamline at the Taiwan Photon Source

Giorgio Margaritondo

The new Brain Imaging Beamline (BIB) of the Taiwan Photon Source (TPS) has been commissioned and opened to users. The BIB and in particular its endstation are designed to take advantage of bright unmonochromatized synchrotron X-rays and target fast 3D imag ...
