Ushiba, Aso

We inspected the MCF and MCE chambers to check the workability for the installation of the new side stoppers.
Then we noticed that some components are different from the CAD model.

So we took out the currently installed EQ stop plate and measured various dimensions.
The problematic one is the small adapter block between the frame and the EQ stop plate.

We updated the CAD model according to the measured dimensions. Then designed new adapter blocks so that the newly designed EQ stop plates, which assumed wrong dimensions, can still be used.

The design of the new adapter blocks and the updated installation procedure document can be found here:
