Integration sequence in phase with subsystems delivery
Integration and Test Plan (LTS-104) describes the general strategy, includes the integration and test sequence and provides a summary for all major key activities.Three Major Phases:Phase 1 (P1): Heavy ConstructionPhase 2 (P2): Mirrors Coating and IntegrationPhase 3 (P3): Alignment Phase
START
ENDP1
P2P3
Phase 1 Heavy Construction• Summit Facility construction (lower enclosure, support building, platform lift, AT lower enclosure)• Provide early access for Dome Installation (lower enclosure and pier ready) and Coating Plant
installation• Crane + Manpower to build Dome included in I&T WBS (supervisory from dome contractor). Mount
and Coating Plant Installation on site included in contract.• Dome Light/Wind Screen installation finalized after Mount installation for shutter door access
Laser Tracker used during Integration

Phase 2 Starts after end of heavy construction for safe handling of mirrors
• M2 Coating during Mount Testing (overlap with Phase 1)• M2 is first installed on Telescope Mount• M1M3 Mirror Reception and Integration in cell• M1M3 coating and assembly (Mount locked at Zenith)• Calibration Screen installed on Dome during M1M3 coating• M1M3 integration on Telescope

Phase 3 starts with M3 tests for 3-Mirror Telescope testing
• Repeat M3 Mirror System performance tests under full active control at zenith pointing (with interferometer)
• Install Integrating Structure with wavefront sensor (WFS)
• On-axis 3-Mirror Telescope Alignment (take advantage of diffraction-limited image on-axis by design)
• Perform Calibration Equipment Tests
