Handling the nanometer
- Michele Modena (CERN)
This talk presents an active vibration isolation strategy combining centralized interferometric inertial control and decentralized force control loops. The strategy will be illustrated on simple models, and then applied to isolate an extended structure from ground vibration. Preliminary experimental results will be presented and discussed.
The objective of this research project is the design of a long range nano-positioning system for the CLIC electromagnets ($m ≅ 80kg$).
CLIC (Compact Linear Collider) is a next generation particle collider under study at CERN. The accelerator will operate beams of nanometric size ($1 nm$ ×$40 nm$) and produce a high density of collisions at the interaction cross section ($2$ x $10^{34}$ ...
Precision engineering tasks require active isolation systems that are efficient especially at low frequencies. The limitations of such control systems include the resolution of the sensor used and the magnetic coupling between the sensor and the actuator. In order to bypass these limitations, inertial sensors using Michelson interferometer are being developed. A first prototype has been built...
