Outline Scope WBS Overview Layout Design Requirements for WBS Sections Summary Schedule Funding Staffing

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

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. 1000 nodes and expandable offers necessary safety and access options for users Beamline Controls EPICS based or compatible (coordinate with LCLS global controls)

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

1.6.03 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 1.6.3.1 Chamber Support Tables 1.6.3.2 Vacuum Components Standard catalog items 1.6.3.3 Experimental Chambers Flexible design to house various types of samples (gases, clusters, solids) Accept various detectors

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 1.6.4.1 Ti:Sapphire Oscillator 1.6.4.2 Diagnostics 1.6.4.3 Supply 1.6.4.4 Laser timing (~0.1ps, shot by shot measurement) 1.6.4.5 Laser amplifiers Pulse length 30fs Wavelength 800nm Repetition rate 1kHz Pulse energy 1mJ → Design based on existing system at SPPS → Catalog items

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 100-200 μm → Detector area >500x500 pixels

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 LCLS Atomic Physics Group formed Members: Lous F.

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
