  1. Lasti UpdateJuly 25, 2007LIGO-G070566-00-Z Rich Mittleman

  2. Over the Last Few Months • BSC Internal Seismic Isolation (ISI) • Quadruple Pendulum Noise Prototype Assembly • Triple-Quad Cavity

  3. Other Work • Bolt Friction and strength measurements Sharon Rapoport • Initial Ligo Test mass standoffs David Kelley Gregg Harry Rai Weiss • Sas Test Alberto Stochino Riccardo DeSalvo Virginio Sannibale Dave Ottaway Dennis Coyne • Baffle Scattering Measurements Cassi Hunt Mike Zucker • Pondermotive Experiment Thomas Corbitt Tim Bodiya Chris Wipf Nick Smith Sarah Ackley Nergis Mavalvala

  4. Moving Offices

  5. BSC-ISI Progress • All Major parts are back from Italy mostly clean and mostly undamaged • Livingston has provide a full complement of sensor pod, which are currently being tested • Assembled All Three Stages • Hoping to be installing the springs this week

  6. Assembly Crew • Myron MacInnis • Stefany Foley • Ken Mason • Bob Laliberte • Sharon Rapoport • Hugh Radkins • Corey Gray • Joe Hanson • Brian O’Reilly

  7. Assembly Pictures

  8. Quadruple Pendulum Progress • A whole lot of heli-coiliing • Most of the masses have been assembled

  9. Quad Assembly Grahmn Woan Tim Hayler Joe O'Dell Ian Wilmut Brett Shapiro Crew Planning on erecting the gazebo and hanging The masses next week

  10. PonderMotive Squeezing Looking Forward to having their own vacuum system

  11. SAS Alberto Stochino is defending his thesis this week

  12. Cavity Work The controls-quad (in the BSC), mode cleaner triple (in the X-end Ham) is now locking reliably. We have used feedback to the frequency input of the laser and the test mass of the triple. We have turned the ESD on and seen movement of the test mass. • Matt Evans • Lisa Barsotti • Fabrice Matichard • Brett Shapiro • Ian Duke

  13. Looking Ahead ISI Assembly Quad Assembly (Metal Test mass) Early August ISI + Quad into BSC October Glass Optic and Fibers November December Glass ETM into BSC

  14. Experiments/Tests • Electro Static Drive (ESD) • Ring Heater • Locking & Control • Violin Mode Damping • ISI Commissioning • Optic Modes and Damping (Parametric excitation) • Baffle Fit Check • Uv charging

  15. Further into the future • Convert to ITM configuration • Install HAM-ISI • Install Recycling suspension • Advanced Ligo TCS test
