3. Working groups for important interface issues

4. Parameter list

  • Parameter list is here.

  • Glossary is here.

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.
