Comparison of simulation tools for LCGT
Several simulation tools with theoretical line using LCGT 2007 parameters are compared here, FINESSE, Thomas, Oprickle. Except for FINESSE.
Theoretical: just analytical way shown in LCGT design document on page 14.
- FINESSE: 'ps2S' and 'scale meter' commands are used for the unit in m/rHz and 'fig' command are used to produce excitations in frequency domain. FINESSE seems to have a bug of a factor by sqrt(2), but it can be compensated later if you know this information to match other results.
- Thomas: Developped by Thomas Corbit. Visual C++ besed, running only Windows machine. This is the first simulation tool which can calculate quantum effect using two-photon modes.
- Optickle: Very flexible simulation tool. You can use a full set of Matlab functions. This tool also can calculate full quantum effect. Optickel RF calculation seems to have a bug of a factor by sqrt(2) for the radiatoin pressure noise, but DC readout calculation is OK. This bug can be compensated to put 2*sqrt(2) instead of 2 on the setMechTF function but radiation pressure noise for DC readout will be larger by a factor of sqrt(2) in this case.
BRSE, with loss, radiation pressure noise for LCGT parameters
20090930_simall_BRSE_loss_rad.zip
Optickle RF result is lower by a factor of sqrt(2) than other results due to the bug explained above.
