  1. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT ADAPTIVE SECONDARYMECHANICS CONSTRUCTION STATUS REPORTArcetri, 21.02.2005D.Gallieni (ADS International)

  2. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 PRESENTATION OUTLINE • the adsec construction process • where we are: mechanical components manufacturing and integration • unit #1 integration detailed plan • shell handling issues • installation procedures and tools • interfaces and maintenance issues • conclusions

  3. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005

  4. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 THE ADSEC CONSTRUCTION PROCESS • ADS: • mechanical compoents manufacturing • integration (structure + optics) • magnets gluing • MICROGATE: • ( electronics manufacturing ) • integration of the electronics on the optomechanical assembly • electromechanical testing • ARCETRI: • optical testing • calibration

  5. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION - WHERE WE ARE • CONSTRUCTION: • all the components for BOTH units have been manufactured together • items still missing: • coldplate #2 (pending the measure of its backplate holespattern) • about 500 magnets (deliverd 100/month) • about 200 actuators inclding spares (new machining run after LBT672a is completed) • hub #1 and #2 • hexapod #2 ( ? ) • LBT672a INTEGRATION STATUS: • actuators coil winding - DONE, for both units • magnets integration - DONE • crates integration - DONE, for both units • BP-CP “dry integration” and alignment check - ONGOING

  6. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION WHERE WE ARE • ACTUATORS: • 1200 actuators produced and integrated

  7. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION WHERE WE ARE • SHELL SAFETY: • bias magnet installed into each coil bobbin  1.4 g passive pulling force

  8. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION WHERE WE ARE • PERMANENT MAGNETS: • 800 magnets produced and integrated • efficiency = 0.55  0.61 N/sqrt(Watt) MMT336 = 0.35 N/sqrt(Watt)

  9. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION WHERE WE ARE • CRATES: • 6 crates integrated • PCB heat sinks ready for both units

  10. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION WHERE WE ARE DISTRIBUTION BOARDS INTERFACE CHECK

  11. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 LBT672 CONSTRUCTION WHERE WE ARE LBT672a PRE INTEGRATION

  15. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 INTEGRATION STAND

  16. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 TRANSPORT STAND

  17. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 TRANSPORT STAND 2

  18. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 INSTALLATION

  19. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 INTERFACES • HUB INTERFACES: • mechanical coupling to swing arm 4 x 4 screwed flanges • adsec & hexapod J-box (150x300mm) • cooling line manifolds (IN & OUT) • 11 lit/min • DT = 2.6 C • TIN issue (cool first coldplate) • DP < 1 bar

  20. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 MAINTENANCE • OPTIONS: • dismount the whole hub and operate into the clean room • time issue • on telescope activity (gap gleaning) • shell centring issue

  21. LBT Adaptive Optics meeting Arcetri - Feb. 21-24, 2005 CONCLUSION(S) • INTEGRATION: • started “full steam” • […]
