SLAC Report 611
• Build instruments for hard x-rays that address 3 Thrust Areas: – X-ray pump-probe– XPCS– Coherent x-ray imaging
• Include one additional instrument, to address the soft-x-ray portions of pump-probe and coherent imaging Thrust Areas
• Detector development
LUSI Scope
LUSI and LCLS Science
AMO, other soft x-ray and diagnostics
X-ray pump probe
Near Experimental Hall (NEH) and Hutches (H1,H2,H3)
• Soft x-ray pick-off mirror in the FEE will provide a soft x-ray beamline for H1 (and possibly H2), allowing efficient switching between experiments
• Mirror system at end of NEH will provide for x-ray beam deflection to 3 hutches in FEH
H1
H2
H3
A soft x-ray pick-off mirror in the FEE will provide a ‘soft x-ray beamline’ for Hutch 1 (and maybe Hutch 2), allowing easy switching between experiments

2-d Detector Development• LCLS experiments need new detector technology• Established LCLS Detector Advisory Committee to evaluate technology choices and monitor
development– Next meeting Feb 9-10, 2006
• Dual development strategy for fast 2-d detectors for ‘hard’ x-rays– Several technologies look promising, no clear leader
– LCLS will pursue one strategy: Pixel Array Detector• Initial development has begun
– LUSI will try a different technology: Silicon Active Matrix• MoU and technical addendum in place as of mid-April
– Both prototypes should be ready by 2009
• Continue to look at available commercial technologies• Need 2-d detectors for soft x-rays
Streak Camera Development
• LCLS experiments can benefit from improvements of x-ray streak cameras.
• The streak camera can be a real aid in commissioning the x-ray split/delay, real time measurement of time delay in pump-probe
• LCLS is responsible for initiating this development, LUSI is considering the cost/schedule-science of assuming the streak camera development project.
SAC recommendations for Soft X-rays
• ‘Proceed’ with soft x-ray imaging of magnetic materials
• Soft x-ray pump probe – strengthen science case
• Soft x-ray RIXS – requires a ‘mature’ LCLS for this exciting science
Response to SAC recommendations for Soft X-rays
• ‘Proceed’ with soft x-ray imaging of magnetic materials– Incorporate into imaging team: added Jan Lüning as
co-leader
• Soft x-ray pump probe – strengthen science case– Incorporate into pump-probe: added Anders Nilsson
as a co-team leader.
• Soft x-ray RIXS – requires a ‘mature’ LCLS for this exciting science
Original SAC review of LOIs: All LOIs can be ‘accommodated’In one of five thrust areas.
