Core IFO Model

The core IFO model will be a simulation model which describes the interferometric part of LCGT. Calculating the behavior of the electric fields inside the interferometer is the main task of this model. This model will also simulate radiation pressure forces from the electric fields to the mirrors in order to provide an interface with the mechanical system.

Analytical model



  • Author: Masaki Ando
  • Platform: Matlab

Default design in 2007(BRSE). This model was designed for TAC meeting held in 2005/5/23.

  • Author: Osamu Miyakawa
  • Platform: Matlab

This is a set of scripts to calculate the loop noise for AdLIGO parameters running on Matlab using Optickle engines. It produces many usuful plots to compare LCGT optical configurations conveniently. The radiation pressure effects are implemented in all optical gain matrix, and the carrier vacuum are available form dark port, laser, pox, poy and attenuators (but the RF vacuum is not yet.). See attached readme.txt for more detail.
