Dynamic analysis of the FF magnets pre-isolator and support system

Due to the very small beam sizes, the final focusing elements at the future CLIC linear collider need to be stable against vibrations to below one nanometer at frequencies above about 4 Hz.

Sumario:Due to the very small beam sizes, the final focusing elements at the future CLIC linear collider need to be stable against vibrations to below one nanometer at frequencies above about 4 Hz. One of the main elements in the strategy to achieve such a stable environment is a passive, heavy pre-isolator supported by pneumatic vibration isolators. In this note, the results from the dynamic finite element analyses of the proposed design for such a passive pre-isolator at CLIC are presented.
