3. Scope of Endstation Systems
Provide the infrastructure for the interface between the LCLS source and its scientific applications:
Personnel protection systems (PPS) Protect people from x-rays, lasers, etc.
Machine protection systems (MPS) Protect machine from clumsy people
Network and computer support Cables, networks, servers, data storage
Beamline controls Hardware, software
Synchronized laser system fs laser system synchronized to FEL
Prototype detectors
Instrumentation for initial atomic physics experiments

6. 1.6.02 Controls Cabling Network and PC Support Beamline Controls
HV, LV, control, signal (fiber) in conduits, trays
long distances (tunnel length 250m)
includes FEE, NEH, Tunnel, FEH (coordination with XTOD 1.5)
Network and PC Support
Data storage and transfer (high data rates from 2D detector: 500*500pixels*10bit*120Hz reprate~60MB/sec) ⇒ GB network
SSRL’s Structural Biology Beamlines have such a GB network:
GB network design meets XES physics requirements
ca nodes and expandable
offers necessary safety and access options for users
Beamline Controls
EPICS based or compatible
(coordinate with LCLS global controls)

7. 1.6.02 Controls PPS (X-Ray and Laser) MPS User safeguards
Beam stoppers, absorbers (low Z/high Z sandwich design)
SLAC Radiation Physics Group (Reports RP-04-13,14)
Shielding requirements for CF and hutch design
X-ray and Laser PPS similar to SPPS layout
MPS
Valves, interlocks, detectors
MPS based on design similar to SPPS, SSRL
User safeguards
Gas monitors for underground hutches
safeguards required by SLAC safety committee

8. Mechanical and Vacuum
Entire LCLS X-ray beam path is under vacuum
→ Requirements: - Average pressure < Torr
- Pump life > 10 years
→ Varian StarCell ion pump has an estimated lifetime of 80,000h (9.1 years) at Torr
- Interface with 1.5 XTOD
Chamber Support Tables
Vacuum Components
Standard catalog items
Experimental Chambers
Flexible design to house various types of samples
(gases, clusters, solids)
Accept various detectors

9. 1.6.04 Laser Systems → Design based on existing system at SPPS
Provide fs laser system synchronized to FEL (NH, FH)
Provide timing structure for user’s external lasers
Ti:Sapphire Oscillator
Diagnostics
Supply
Laser timing (~0.1ps, shot by shot measurement)
Laser amplifiers
Pulse length 30fs
Wavelength 800nm
Repetition rate 1kHz
Pulse energy 1mJ
→ Design based on existing system at SPPS
→ Catalog items

10. 1.6.05 X-Ray Detectors Four detector prototypes planned:
Beam Imaging → probably CCD based
Beam Intensity → need wide dynamic range
⇒ Detect and characterize beam for particular experiment
3. Streak Camera → provide FEL-laser synchronization to ~0.5ps for experiments
4. 2-D X-ray Detector
⇒ Stimulate R&D for one type of detector
→ dynamic range → 120Hz readout
→ sensitivity 1 photon at 8keV → DQE >50% at 8keV
→ pixel size μm → Detector area >500x500 pixels

11. 2.6.07 Atomic Physics →This WBS section was added most recently
→First step for understanding interaction of
unique LCLS beam with matter
Experiments not yet precisely defined

18. Summary Accomplishments: Conducted TDR and EIR (Dec.03, June 04)
Cost, schedule and project baseline established (March 04)
Basis of estimate completed (June 04)
Atomic Physics Advisory Group formed (March 04)
Participated in Conventional Facilities planning meetings
Challenges:
General:
Steep staffing profile in FY-06
Availability of Conventional Facilities impacts start of installation
Technical:
2D-X-Ray Detector: Largest R&D effort. Proposed development plan to manage risk
Laser-x ray timing: Experience being gained through SPPS
Cost and Schedule:
XES is a $19M project nearly even split between labor and materials
Majority of activities have been done previously at SSRL, SPPS and can be scaled
Procurements mainly “off the shelf”
R&D activities concentrate on 2D X-ray Detector and laser timing synchronization
Design phase starts in FY05; by FY06 in all areas
