|
Mike Vogel reported that alignment of the Q1Q2 assembly w.r.t. the T2 and B1 flanges was completed on July 7. This was performed in the test
stand with the flange positions set to the measurements taken in the 2019 shutdown. Alignment to the theoretical location was achieved within 0.1mm.
The axis of the Q1 and Q2 magnets were aligned to each other previously within similar accuracy. |
