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 shielded X-ray spectrometer 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.
Perspective for Run 22
In addition to the standard configurations, users are encouraged to take advantage of developing capabilities at MEC, in close consultation with the Instrument Team.
- The new standard beam delivery platform for the short pulse laser providing for easier setup of experiments using the short pulse laser, whether in full intensity, frequency doubled, or uncompressed mode.
- A new spectrometer capable of high resolution data in harsh EMP and bremsstrahlung environment (the XTCS) as well as a new compact von-Hamos sepctrometer for collective-hungry experiments.
- The UXI detectors from Sandia National Laboratory, allowing up to 4 frames separated by few ns, of particular interest for ns long dynamic studies.
Laser-only time through LaserNetUS
Starting in 2019, FES has provided funding for MEC to offer a limited amount of laser-only time (no LCLS X-rays) through the LaserNetUS consortium. See lasernetus.org for more information.
