The KEKB B-Factory will be upgraded to SuperKEKB using the same tunnel
as KEKB. The SuperKEKB design peak luminosity is 40 times higher than
the world record luminosity which KEKB has achieved. The upgrade is
based on the “Nano-Beam” scheme, wherein the beam size is reduced to
less than 100 nanometers in the vertical direction at the interaction
point (IP). Vibration in the tunnel,...

The concrete slab of the PETRA III experimental hall has a size of roughly 300x30m and a thickness of 2m. Movements due to temperature variations and setting of the concrete are discussed. Methods of predicting future movements are developed.
