Budgeting and control of the mechanical noise in the International Linear Collider final focus system

Budgeting and control of the mechanical noise in the International Linear Collider final focus system

In this paper, we present a simplified vibration model of the silicon detector (SiD), where the final doublet (QD0) is captured inside the detector and the penultimate magnet (QF1) is inside the machine tunnel. Ground motion spectra measured at the detector hall at SLAC have been used together with...
