3. Working groups for important interface issues
Layout (VAC,MIF,AOS,IOO, etc.)
Cabling (VIS,CRY, etc.)
Interlock (MIF,IOO,LAS, etc.)
Detector diagnostics (MIF,DAS, etc.)
Connectors (VAC,CRY,DGS etc.)
4. Parameter list
5. Requirements and tolerance
Requirements are given in the parameter list. Each parameter must be not so far from the required value as to deteriorate the sensitivity by less than 1%.
Tolerance is given for some of the parameters by calculating the robustness of the sensitivity. See here.
6. Duty factor
The target duty factor of KAGRA is 80%. Breakdown of the time loss is shown here.
