DCO Physics Requirements
Goals
Build diagnostics and common optics to help XPP, CXI, and XCS
instruments achieve their full scientific potentials
Common requirements stemmed from characteristics of LCLS X-ray
FEL
Ultra short @ 100 fs, and repetition rate of 120 Hz
High peak power ~ 10 GW
Fully coherent in transverse directions ~ TEM00
Intrinsic intensity, temporal, spatial, timing fluctuations on per-pulse basis,
i.e.,
LCLS Expected Fluctuations
Pulse intensity fluctuations
Position & pointing jitter
(x, y, a, b)
Source point jitter (z)
LUSI DOE Review
Aug. 19, 2008
Diagnostics/Optics (WBS 1.5) p. 11
~ 30 %
(in contrast to synchrotron where
fluctuation is Poisson limited)
~ 10 % of beam diameter
~ 10 % of beam divergence
~5m
(leads to variations in apparent source
size, or focal point location if focused)
Yiping Feng

DCO Physics Requirements (cont.)
Unique challenges identified for LUSI DCO
Capable of sustaining the instantaneous LCLS X-ray FEL peak power
Exercising deliberate material selection
Thermal calculations including melting threshold and onset of thermal fatigue
Capable of coherent beam manipulation
Minimizing large angle diffractions to the extent possible
i.e., utilizing cylindrical blades for slits
Minimizing random wavefront distortion to the extent possible
Reducing surface roughness and bulk non-uniformities
Capable of ultra-fast signal detection
Extracting signals in ~ ns to avoid large background
i.e., charge-sensitive detection in intensity measurements
Capable of per-pulse measurement if required
Each pulse is a new experiment
Averaging NOT an option, requiring high S/N ratio from single pulse
i.e., high-precision intensity measurements to 0.1% based on single pulse
