finesse simulation O4
This simulation aims to replicate simulation result from Optickle to get transfer functions between sensitivity and benches movement on Virgo.
The final objective is to use Finesse to compute future backscatter noise projection.
Getting started
This project use uv to manage dependencies, and mise to manage python version and virtual environment.
To run the program, you can use jupyter lab to run the main notebook. By running the following command:
uv sync
jupyter lab
Note
You can still use pip to manage dependencies using pyproject.toml
Sensitivities
The reference file is taken from Virgo observation data on the 7th of June 2024, (500 second from GPS time: 1401789000)
The other file is generated using this notebook
Optickle comparison
The file optickle.mat was obtained using this
version
with the 59 & 60 lines of DRITF/scatterRadiationPressure removed and the lines
51 & 52 updated to:
par.P_darkFringe = 8
par.P_laser = 25
Which means the result were obtained with a aligned SR mirror, like in the Finesse simulation
Content
- main.ipynb contains code for a simulation using only the TEM00 mode.
- high order mode.ipynb simulate high order mode, with a rotated SR.
- work.ipynb contains code to visualize high order mode.
