Making Invisible Cracks Visible

Making Invisible Cracks Visible | Physics | Scoop.it
A new acoustic imaging technique could reveal previously invisible cracks in bridges or other infrastructure.
Mikko Hakala's insight:

A new nonlinear ultrasonic acoustic imaging technique is developed for detecting cracks in materials (due to e.g. fatigue).

 

The technique is simple and practical because it uses standard imaging equipment and is based on established linear methods.

Upgrade for European light source

Upgrade for European light source | Physics | Scoop.it

European Synchrotron Radiation Facility (ESRF). One of Europe's premier scientific research laboratories is to go through a major upgrade.

Mikko Hakala's insight:

 

European Synchrotron Radiation Facility (ESRF) is a most powerful X-ray machine in Europe, supported and shared by 20 countries. See http://www.esrf.eu/ ;

 

ESRF is going through a major upgrade. This BBC article by @BBCAmos (via @tmertzi) tells some essential information what this means to ESRF. See how much more radiation will be obtained, how much will the upgrade cost and the timetables.

 

How synchrotron X-rays are generated and how research is done with them? Here is one recent video from a canadian synchrotron explaining basic operation:
