How to support the quadrupoles? Comparison control laws and former stabilisation experiments … CLICMeeting100409 C. Hauviller 38
How to support the quadrupoles? Soft versus rigid ? Soft: + Isolation in large bandwidth Rigid: - High resolution required actuators - But more sensitive to external forces - Elastomers and radiation But available in piezo catalogues + Robust against external forces + Nano positioning External forces: vacuum, power leads, cabling, water cooling, interconnects, acoustic pressure,….
