Instrumentation & Vacuum Briefing

Science is done in just about every corner of the globe but many researchers lack access to the cutting-edge instrumentation available at large facilities such as synchrotron light sources and neutron-science centres. Widening this accessibility is an important theme running through this free-to-read briefing.

A diagram of the Earth's crust in cross-section, showing supercritical fluids and gases (denoted by red and blue arrows) breaking through a blue line representing the seal layer along a thick black line representing a fault. The result is seismic vibrations, shown here as a cluster of stars at the point where the breakthrough occurs. A scale on the side shows that this process occurs at the boundary between brittle and ductile layers of rock, at a depth of around 2.5 km below the Earth's surface.
