= Project Overview =
 * Design and ASC scheme after we design one for AdvLIGO 
 * Implement and test the new InGaAs, in-vac, high power, FTC WFS. The 40m WFS need not be 
  . in-vac, but they should be packaged as such. 
 * Measure spring stuff 

= Control Models =
 . [[Simulink Model of 40m Optical Springs]] 

= Results and Discussions =
 This file [[attachment:40m.pdf]] contains some results for the 40m ASC sensing matrix.

 . The input for this calculation was taken from 40m web page: http://www.ligo.caltech.edu/~ajw/40m_upgrade.html. The loss per optic was increased from 37.5 ppm to more realistic 100 ppm.
