Type-A control meeting 2020/8/4

Agenda

Modal Damping
- Near term
  - Implement it to one of the ETMs (Nakano, Miyo)
    - Try lock acquisition
  - If the above works, implement to all the Type-As (Nakano, Miyo)
    - Then lock PRFPMI and check the low frequency noise
- Longer term
  - If successful with Type-A, implement it to all the other suspensions.
- Improvement
  - Form optimal combinations of actuators for each mode
- Integration with Simulation
  - Import the modal damping for one of the modes to the current model (Shoda)
  - See if we can reproduce the phase delays between stages by introducing asymmetries in the suspension model (Shoda)
Eddy current damping of MN coil bobbins
- More detailed calculations with the method described in https://arxiv.org/abs/2007.09571 (Ushiba)
