Optickle for the PRFPMI at the 40m

attachment:Optickle_prfpmi_40m.zip

• In the folder 40m_PRFPMI the parameters have been set to mimic the state that the smoo_prfpmi script gets us to. See Rana's ilog entry.

• The initial conditions are such that the arms are on resonance, the MICH is at 0.8 of a bright fringe, the PRC is at resonance for the carrier (power builds up in the PRC).
• Transmission of the signal recycling mirror is set to 1 in the opt40.m parameter file.
• Slightly cleaned up version of Kirk's: attachment:powfab.zip
  • (unzip into the directory where you want your powfab Optickle files)
• Added a spob detector to opt40.m. Changed the losses of the optics to be more accurate (from 1ppm). to PR = 60ppm, SR = 60ppm, BS = 100ppm, ITMX = 100ppm, ITMY = 100ppm, ETMX = 100ppm, ETMY = 100ppm. attachment:smoo_PRFPMI.tar.gz

OPTICKLE Configuration files for Optickle: attachment:Optickle_DRFP.zip Run cfg40m to create an "opt" file, then run tickle

LOOPTICKLE

attachment:Looptickle_DRFP.zip

"test40m.m" is based on Stefan's example "demo40m.m". Put the other files in the config directory and run test40m in the looptickle directory to produce a plot with the noise budget. N.B.: Filters and gains are the ones defined in Stefan's model, TUNING NEEDS TO BE DONE.
