====== Project: Autoalignment of the Reference Cavity of the AEI-10m  ======

===== Aim of this project (January 2010)=====

**The aim of this project is produce a design document for the auto alignment system of the reference cavity for the AEI-10m by April 2010.**
This is a very preliminary list of topics that we should cover in this report:
  * Position of quandrant detectors and spot position detectors
  * Computing the corresponding control matrix and optimising it for orthogonality. This will probably include designing the gouy phase telescopes.
  * Define the actuators and show that they are 'properly' orthogonal
  * Define RF modulation frequency and choose photodiode design
  * Noise Analysis of the system? 
  *





===== 1st Draft of Design from Fumiko (April 2010)=====

Here is the document:  {{:geo-isc:aa_aei_proto_fst_dft.pdf|aa_aei_proto_fst_dft.pdf}}

Note from Fumiko's email: "There is still a need to discuss to finalize this version, and this one is subject to change although not a big nor fundamental change."

I finished it and put it here, thanks.

===== Review of the Design document (May 2010)=====

Rolland Schilling and Andreas Freise agreed to serve as 'official' reviewers for this project.
