Cost & Schedule Performance – WBS 1.5
The x-ray pump-probe instrument will take advantage of the ultrashort pulse duration of the LCLS to take snapshots of a photo-induced phenomena. In general, the experiments performed as this endstation will use an ultrafast laser pulse to initiate a transient response in a system. The system will be probed using various x-ray scattering techniques. The time evolution of the response will be mapped by variably delaying the arrival time of the x-ray pulse with respect to the pump laser pulse. The success of this end station will depend upon the ability to accommodate a wide variety of laser excitation techniques, samples, sample environments and x-ray scattering methods.

The project is monitoring strings of activities with the least float

Summary Scope of DCO components for XPP, CXI, and XCS instruments has not changed significantly since CD-02 The design of key diagnostics devices and optical components is mature and based on proven developments at synchrotron sources worldwide by XTOD and LCLS e-beam groups No major risks associated with the design or procurement of the DCO components Bought components (slits) are “off the shelf” items Assembly components (CCD cameras, zoom lens, actuators, connectors) are commercially made with known performance In-house electronics design are based on proven technology and implementations DCO overall cost and schedule performance is kept within margins. Critical Path is defined and monitored Advanced Procurements identified DCO is on track to support accelerated schedule! Page 23

Challenges Addressed Scientific/technical challenges that were addressed Sustaining the instantaneous LCLS X-ray FEL peak power Exercising careful material selection Filters, scattering target, slits materials, focusing lens, beam stop etc. Based on thermal calculations including melting threshold and onset of thermal fatigue & limited experimental data from FLASH But no active cooling necessary Providing coherent beam manipulation Minimizing wavefront distortion/coherence degradation Filters, scattering target, slits, focusing lens Reducing surface roughness and bulk non-uniformities Minimizing diffraction effects i.e., utilizing cylindrical blades for slits

Challenges Addressed Scientific/technical challenges that were addressed Detecting ultra-fast signals Extracting electrical signals in ~ ns to minimize dark current contribution i.e., charge-sensitive detection using diodes Making per-pulse measurement if required Each pulse is different Averaging over pulses may NOT be an option, requiring sufficiently high S/N ratio for each pulse i.e., high-precision intensity measurements at < 0.1% based on single pulses, requiring larger raw signal than synchrotron cases
