Adv. LIGO Seismic Isolation (SEI)Schedule: R&D/Design Phase

Technology Demonstrator and Controls Development Testbed» Approx. full scale, HAM-like unit installed in the Stanford University

Engineering Test Facility (ETF) vacuum system

» Verify kinematics & dynamics of design ( completed)

» Further the servo-control development begun on the proof-of-concept, two-stage system (currently in process)

» Expect initial phase of servo-controls development in support of the LASTI prototypes by 4thQ 2004



“Pathfinder” Prototypes part of Preliminary Design

» Full scale, HAM and BSC units (1 each) for the LASTI integrated test system

» External Pre-Isolation (EPI) stages– Already in place at LASTI on a HAM and a BSC chamber – One unit must be reworked once a technology decision is

made (electro-magnetic vs hydraulic actuation); decision Jun2003

» RFP (“tender”) for 2 phase structural design issued Apr2003

– Proposals are being evaluated now – Source selection for phase 1 (value engineering) in Jun2003

– likely 3 awards– Source selection for phase 2 (design & fabrication) in

Sep2003 -- likely 2 awards– Hiatus during LASTI SEI subsystem testing before

production phase (phase 3)



Preliminary Design Review (PDR) held Apr 2005» After assembly and installation experience at LASTI

» Follows 5 months of “Pathfinder” stand-alone prototype testing at LASTI

Production and procurement of long lead items initiated after PDR

Final Design Review (FDR) held Nov 2005» After integrated SUS/SEI testing (test for coupled

dynamics/interaction)

WBS 4.02.4 SEI Fabrication» 4.02.4.1 Fabrication/Procurement» 4.02.4.2 Assembly» 4.02.4.3 Alignment, Calibration and Test» Total duration is 42 months for 30 units

WBS 4.02.4.1 Fabrication/Procurement» Scope includes:

– procurement of commercial off the shelf components, e.g. sensors, processors, racks, crates, etc.

– contract fabrication of custom equipment, e.g. UHV actuators, structure, etc.– In-house fabrication of custom conditioning electronics– Assembly

» Start of Jun2005 enabled by completion of LASTI HAM & BSC SEI prototype test completion, plus test and design review

» Estimated total duration is 29 months, of which structural fabrication is 24 months» Recent structural fabrication incumbent bidder estimated 23 months total required for

the production phase» First interferometer set of hardware ready for assembly 13 months after start, or

Jul2006


Adv. LIGO Seismic Isolation (SEI)Schedule: Project Phase

WBS 4.02.4.2 Assembly WBS 4.02.4.3 Alignment, Calibration and Test

» Scope includes:– Receipt/acceptance of materials/components and sub-assembliees

(assembled structure, sensor/actuator pod structures, sensors, actuators, in-vacuum cabling, etc.)

– Clean room assembly of SEI systems (HAM and BSC chamber versions) by LIGO Lab at LLO

– Alignment of sensors, actuators, flexures; balancing & calibration of actuation & sensing

– Functional testing

» Starts Jul2006, when first sets of hardware are received» First interferometer set (5 BSC units and 5 HAM units) completed

by Jul2007 (12 months)» Next 2 interferometer sets (10 BSC units and 10 HAM units)

completed Feb2009 (20 months)

Adv. LIGO Seismic Isolation (SEI)Costs

All costs are in base year dollars (un-escalated) Production cost = $37,952K including 26% contingency Proposed construction cost = $37,952K – 1.7 x $667K direct labor incl.

Indirect = $36,819 Labor costs are borne by LIGO operations funds Average hardware cost = $36,819/30 units = $1,227K each chamber



98.6%



In-chamber mechanical fabrication 50.3% Instruments 19.5% Electronics 14.7% Mechanics 11.8% Assembly, align, calibrate, test 3.1% Controls 1.8%



3 Interferometers (IFOs) x $6,363K = $19,089K for in-chamber Mechanical Fab Contracts


Adv. LIGO Seismic Isolation (SEI)In-Chamber Mechanical Fab. Costs

Adv. LIGO Seismic Isolation (SEI)Instrument Costs

Sensing and actuation topology in relation to the two in-chamber, isolation stages

Sensors:» Low noise, capacitive

displacement sensors (6 between stages, 12 total)

» Seismometers, L4-C (6/stage 1)» Broadband Seismometer, STS-2

(3/stage 1)» Seismometer, GS-13 (3/stage 2)

Electro-magnetic Actuators:» “High” force between stages 0

and 1, BEI Kimko LA50-62-004Z» “low” force between stages 0

and 1, BEI Kimko LA18-32-006Z» Need ultra-high vacuum (UHV)

compatible versions – should be covered by 26% contingency


SEI Instrument Costs


SEI Instrument Costs

Interferometer 1 (IFO1 or LLO) will already have an external pre-isolation (EPI or stage 0) system installed» Instrument costs = $2,273K

IFO2 and IFO3 (LHO) also require instrumentation for the EPI systems:» Seismometers, L4-C, 8 total/chamber» Load Cells, 8 total/chamber» Inductive position sensors, Kaman DIT-5200, 8 total/chamber» Instrument costs = $2,558K for each of IFO2 and IFO3

Total instrument costs= $2,273K + 2 x $2,558 = $7,389K


SEI Electronics Costs

Electronics module counts are based on a conceptual system block diagram employing initial LIGO elements and anticipated processing requirements for the digital control

IFO1 will already have installed EPI (stage 0) systems; IFO2 and IFO3 will not (just as in the case of the instrumentation)

Total electronics costs= $1,513K IFO1 + $2,039K IFO2 + $2,021K IFO3= $5,573K
