LCLS Instruments
The NEH 1.2 instrument will be configured to operate on both the soft X-ray undulator (SXU) and the hard X-ray undulator (HXU) sources with the following configuration requirements:
-
Fixed X-ray beam trajectories
-
Ability to focus the two sources simultaneously into a single micron diameter interaction point where the experimental endstation will be positioned.
-
Ability to efficiently change experimental endstations.
X-ray Requirements
-
Focusing: KB mirrors with 2 stripes (Nickel and Boron Carbide)
- 1.5 μm in vertical
- 0.8 μm in horizontal
- KB's can be removed for unfocused operation or Zone plate operation
-
Photon Energy Range:
-
Soft X-ray Undulator Branch Line
- 250 eV to 5 keV
- Harmonic Rejection between 1.4 and 5 keV
-
Hard X-ray Branch Line
- 1 keV to 7 keV
- Harmonic Rejection between 2.2 and 7 keV
-
-
Allows both copper and superconducting accelerator operations
-
Allows simultaneous undulator operations for X-ray pump and X-ray probe operations
-
Beamline transmission 60 to 90% depending on operation mode
-
Repetition rate: up to 929 kHz (including 120 Hz Cu operations)
