Vibration Analysis of Underground Tunnel at High-Tech Facility
(2010) NSCM 23- Abstract
- MAX-lab is a national laboratory operated jointly by the Swedish Research Council and Lund University. Nowadays it consists of three storage rings and one electron pre-accelerator. Due to the improvement of nanotechnology, a new storage ring is needed. Hence, MAX IV will be 100 times more efficient than already existing synchrotron radiation facilities, becoming a leading facility for studies of particles at a nano-level4.
MAX IV will consist basically in one circular-storage-ring and one linear underground tunnel (Linac) next to it. Both the ring and the Linac converge at one point, where the electrons have already almost reached the speed of light after being accelerated along the tunnel and are then shot into the...

Hence, MAX IV will be 100 times more efficient than already existing synchrotron radiation facilities, becoming a leading facility for studies of particles at a nano-level4.
MAX IV will consist basically in one circular-storage-ring and one linear underground tunnel (Linac) next to it. Both the ring and the Linac converge at one point, where the electrons have already almost reached the speed of light after being accelerated along the tunnel and are then shot into the ring so they can begin to spin around. The beam line is then bent with magnets in order to produce the so-called synchrotron light.
In this investigation, the vibration levels at the Linac were analyzed. Since this construction will be used for high precision measurements, it will be asked to have a very strict vibration requirement where only very low vibration levels will be allowed.
Real finite element models of the Linac were established in order to analyse the influence of the surrounding vibration sources (e.g. traffic) on the tunnel. (Less)
