MEC - Matter in Extreme Conditions

Photo from entrance of MEC Feb 5 2019

The LCLS beam with its high peak brightness, short pulse duration, and tunable X-ray photon energy provides revolutionary capabilities to study the transient behavior of matter in extreme conditions. The particular strength of the Matter in Extreme Conditions (MEC) instrument is to combine the unique LCLS beam with high power optical laser beams, and a suite of dedicated diagnostics tailored for this field of science (including an X-ray Thomson scattering spectrometer, an XUV spectrometer, a Fourier domain interferometer, and a VISAR system). While the large vacuum target chamber makes the endstation very versatile, it has been designed to service key scientific areas including Warm Dense Matter physics, high pressure studies, shock physics, and high energy density physics.

Participation in LaserNetUS

Starting in 2019, FES has provided funding for MEC to offer a limited amount of laser-only time through the LaserNetUS consortium. See for more information.
