LCLS-II Instruments (L2SI)

LCLS-II will be a transformative tool for energy science, qualitatively changing the way that X-ray imaging, scattering and spectroscopy can be used to study how natural and artificial systems function. It will enable new ways to capture rare chemical events, characterize fluctuating heterogeneous complexes, and reveal quantum phenomena in matter, using nonlinear, multidimensional and coherent X-ray techniques that are possible only with X-ray lasers. This facility will operate in a soft X-ray range (250 eV to 1.5 keV), and will use seeding technologies to provide fully coherent X-rays in a uniformly spaced series of pulses with programmable repetition rate and rapidly tunable photon energies.

Instrument Names and Defining Capabilities 

NEH 1.1 or Time-resolved AMO (TMO)

NEH beamline 1.1 will support many experimental techniques not currently available at LCLS. High operational efficiency will be achieved through utilization of multiple fixed endstations. Stable beam trajectories will be provided through streamlined X-ray alignment to the fixed interaction points. Delivering the beam to only a few fixed locations will optimize optical laser experiments and setups.

Both the NAMASTE and the DREAM endstation will be configured to take full advantage of both the high per pulse energy from the copper accelerator (120 Hz) as well as high average intensity and high repetition rate from the superconducting accelerator.

NEH 1.2 or Tender X-ray Imaging (TXI)

Access to the tender X-ray spectral range (1000 eV-5000 eV) as well as the ability to simultaneously receive X-ray beams from both the hard X-ray undulator and soft X-ray undulator.

NEH 2.2

The combination of exceptionally high flux of monochromatic photons, far exceeding that at current state-of-the-art instruments, delivered in the form transform-limited femtosecond X-ray pulses, will make the NEH 2.2 Instrument at LCLS-II one with transformational capabilities. It will enable new ways to capture rare chemical events, characterize fluctuating heterogeneous complexes, and reveal quantum phenomena in matter, using multidimensional and coherent X-ray techniques that are possible only with X-ray lasers. This facility will provide access to the “soft X-ray” regime (250 eV to 1.6 keV) to provide fully coherent X-rays in a uniformly spaced series of pulses with programmable repetition rate and rapidly tunable photon energies.
