## page was renamed from LCGT/subgroup/vis = Vibration Isolation System (VIS) = == Subsystem Definition == 1. This subsystem makes vibration isolation for all optics used in KAGRA. 2. Requirement of displacement of the test mass mirrors must be less than 4x10^-20m/rtHz at 10Hz. RMS motion must be less than 0.1 um as displacement and 0.1 um/s as velocity. （please note that it is old information） Reference [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=365|JGW-T1100365-v2]] ----- ||<#1e50a2 style="color:#ffffff; text-align:center;"> '''Design''' ||<#1e50a2 style="color:#ffffff; text-align:center;"> '''Suspensions''' ||<#1e50a2 style="color:#ffffff; text-align:center;"> '''Mechanics''' ||<#1e50a2 style="color:#ffffff; text-align:center;"> '''Sensors''' ||<#1e50a2 style="color:#ffffff; text-align:center;"> '''Actuators/Motors'''||<#1e50a2 style="color:#ffffff; text-align:center;"> '''Digital System'''|| || Concept? || [[KAGRA/Subgroups/VIS/TypeA|Type-A]] || [[KAGRA/Subgroups/VIS/Mechanics/Pre-Isolator|Pre-Isolator]] || [[KAGRA/Subgroups/VIS/Sensors/InertialSensor|Inertial Sensor]] || [[KAGRA/Subgroups/VIS/Actuators/VoiceCoilActuator|Voice coil actuator]] || [[KAGRA/Subgroups/VIS/RealTimeModel|RTModel]] || ||[[KAGRA/Subgroups/VIS/ActuatorDesign|Actuator Design]] || [[KAGRA/Subgroups/VIS/TypeB|Type-B]] || [[KAGRA/Subgroups/VIS/Mechanics/GAS|GAS]] || [[KAGRA/Subgroups/VIS/Sensors/LVDT|LVDT]] || Solenoid actuator? || [[KAGRA/Subgroups/VIS/Guardian|Guardian]] || ||[[KAGRA/Subgroups/VIS/Requirement|Requirement]] || [[KAGRA/Subgroups/VIS/TypeBp|Type-Bp]] || [[KAGRA/Subgroups/VIS/Mechanics/MagneticDamper|Magnetic damper]] ||[[KAGRA/Subgroups/VIS/Sensors/PhotoSensor|Photo Sensor]] || [[KAGRA/Subgroups/VIS/OpsManual/Pico|Picomotor]] || [[KAGRA/Subgroups/VIS/OpsManual/SDF|SDF]] || || - || [[KAGRA/Subgroups/VIS/Type-C|Type-C]] || [[KAGRA/Subgroups/VIS/Mechanics/MaragingWire|Maraging wire]] || [[KAGRA/Subgroups/VIS/Sensors/OpLev|Optical Lever (OpLev)]] || [[KAGRA/Subgroups/DGS/Projects/StepperMotor|Stepper Motor]] || [[KAGRA/Subgroups/VIS/BIO|BIO]] || || - || [[KAGRA/Subgroups/VIS/TMS-VIS|TMS-VIS]] || - || [[KAGRA/Subgroups/VIS/ReleaseSensor|Release Sensor]] || [[KAGRA/Subgroups/VIS/OpsManual/FishingRods|Fishing Rods]] || - || || - || - || - || - || [[KAGRA/Subgroups/VIS/OpsManual/Traverser|Traverser]] || - || || - || - || - || - || [[KAGRA/Subgroups/VIS/OpsManual/PicomotorPowerControlSwitch| PicomotorPowerControlSwitch]] || - || || - || - || - ||<-2 style="text-align:center;"> [[KAGRA/Subgroups/VIS/Sensors/OSEM|OSEM]] || - || || - || - || - ||<-2 style="text-align:center;"> [[KAGRA/Subgroups/VIS/TempControl|Temp.
