Sekiguchi, Hirose |
Closed. Takanori and Osamu Miyakawa found the document about OSEM (it includes the schematic design of circuit) by themselves. |
Overall design |
Ask somebody in LIGO details of the circuit for OSEM. |

R. Takahashi |
Urgent! |
Overall design |
3-D design drawing of Type-A is necessary (ASAP!). Ask to Gianni. |

R. Takahashi |
Urgent! |
Vertical spring |
About blade metal spring (vertical spring), the schedule and strategy and so on will be summarized by R. Takahashi, Ishizaki, Sekiguchi, and K. Yamamoto, and reported in the next meeting. |

2013 Nov. 19 |
K. Yamamoto |
Urgent! |
Material |
About the masses, including a recoil mass, intermediate mass, intermediate recoil mass, and platform, the evaluation of the eddy current damping is necessary. K. Yamamoto will ask (1) to Eric Hennes how much he can make his effort for this problem and whether he can provide files for Finite Element Analysis. (2) to Ando or Aso whether Nishi's file for eddy current damping still remains. |
