As discussed in the today's meeting, here the list about the tasks list, that have to be done to improve the the performance of the Type B system:

  • Estimation of the IP coupling ratio: L2T, L2Y, T2L, T2Y, Y2L, Y2T
  • IP DC actuators diagonalization: measuring the DC coupling of the IP by pushing it in DC along L, T, Y
  • Optical levers diagonalization method similar to type A one and fixing scale by moving the IP. For Pitch dof we will discuss later.
  • TM actuators diagonalization: using the DC method like IP and checking the residual coupling by injecting whit noise or an high frequency line.
  • Sensor correction: we need to modify the real time model and if it will be available soon we are gonna to implement SC
  • Check the diagonalization of the geophone.
  • Blending: we have to measure the noise of the sensor by looking at the open loop spectra of geophones and LVDT.
  • IP control filters tuning.
