Yamada-kun made a control noise projection from Type-A payload actuators to DARM. (klog#12229)
Plan for coming weeks
- Real-time model update
- To add hierarchical hand-over paths for TM oplev signals
- To add setpoint of the TM oplevs before being sent to damping/DC control filters
Type B
Report for the week 16-12-2019
Limit switch for IM picomotors: last meeting there were concerns about the pin 5 of the in-air cable being connected to shield and the case. The solution would be to use an unshielded cable. See updated slides in this link.
- SR2 neighborhood clean room survey.
I didn't finish this week surveying the clean room. I realized I need more information about the position of the handrails in the 2nd floor. I will measure that on the 14th of January. If the analysis is required earlier another person can take over. I left some files in Dropbox here.
- There's not much space available to extend the clean room by a lot without blocking valuable access into the +X arm. We will likely require to set the oplev optics outside of the clean booth.
- Type-B and Type-Bp oplve survey: I went to the tunnel and took a look but, as expected, important features are hidden under aluminium foil covers. I will collect 3D CAD models for the main components.
I left a very humble TO DO list for commissioning here. I will do this when I come back depeding on the commissioning priorities. Nevertheless, in case anyone wants to do it, please feel free.
