Abstract:
This report is to summarize the results of actuator noise modeling for the KAGRA suspensions. The modeling was done by using MATLAB Simulink based NoiseBudget script made by Chris Wipf.

The latest version is maintained in the KAGRA svn. Please download the latest version from
https://granite.phys.s.u-tokyo.ac.jp/svn/LCGT/trunk/kagranoisebudget/Suspensions/report/ActuatorNoise_ModelingReport.pdf

Keywords:
SAS VIS actuator OSEM MIF
Notes and Changes:
-v11: updated for actuator design change (smaller magnets for BS TM, SRM TM; high power coil drivers for PRM TM/IM)
-v12: updated for OSEM calculation (JGW-T1503239) update; IM coil efficiencies updated for opposed magnets
-v13: updated to include Type-A simulation; included magnetic noise and quantum noise
-v14: included BF feedback for Type-A; corrected minor errors
-v15: removed BF feedback; updated MN magnet size for Type-A
