  1. Advanced LIGO Sensitivity Modeling in MATLAB Clare Bayley, MIT LSC/VIRGO Joint Meeting March 21st, 2008

  2. What is Bench? >> bench7(10,10000,IFOModel,SourceModel,3)

  3. Why is it useful? • Quantum Noise • Seismic Noise • Suspension Thermal Noise • Coating Brownian Noise • Coating Thermo-Optic • Both refractive and elastic • Gravity Gradients • Excess Gas

  4. A Little History Version history: Version 0 – Sam Finn wrote the original version. Thank you, Sam, for getting us going! Version 3.3 - 8/25/2005 – Fixed error with Poisson ratios in coating thermal noise and changed residual gas noise coefficient Version 3.4 - 9/17/2005 – Added thermorefractive noise to noise model Version 3.4a - 3/14/2006 – Fixed error with beam widths in thermoelastic noise Version 4.0 - 4/18/2006 – Incorporated various new features.

  5. Introducing: 7.0 Refactored – Modular Design Plans for GUI Optimization Algorithms

  6. Coating Optimization

  7. More Useful Than Ever It’s not just for LIGO anymore!
