Design of ultra-high speed optical beam chopper rotors

26. October 2021

High-speed beam choppers usually require a fast circumferential and rotational speed and vacuum operation, for which the Celeroton magnetic bearing systems are well suited.

The chopper rotor requires a stepwise design process, which is presented in this White Paper, including requirements definition, mechanical and rotor dynamic design. It is shown that circumferential speeds up to approximately 1 km/s are feasible for discs made from Titanium and jitters of smaller than 4 ns can be achieved with such a design and Celeroton magnetic bearing systems.
