Design:
- Statically determined design, thinking in degrees of freedom.
- Designs optimized for position accuracy and stability;
- No friction, no play, low hysteresis.
- Use of thermal centre, thermal length compensation.
- Separate force frame and metrology frame.
- Stiffness compensation, weight compensation.
- Mechanisms based on elastic elements.
- Designs optimized for dynamical performance (low mass, high stiffness).
- Electromagnetics;
- Actuator design (Lorentz, reluctance type).
- Magnetic bearings.
- Dimensional metrology principles.
- Design for high voltage, ultra-high vacuum and extreme temperatures
- Low-magnetic and non-magnetic constructions and mechanisms.
- Understanding of optics, control, electronics and mechatronics.
- Mechanics (stress, strain, fatigue / lifetime).
- Dynamical behaviour (using lumped-mass reduction models).
- Position accuracy prediction (using lumped-mass models, Wittgen method).
- Magnetic circuit analysis.
- Steady-state thermal modelling.
- Thermo mechanical stability estimation.
- Fluid cooling system analysis (pressure drop, heat transfer).
- Finite Element Analysis (static, dynamic, thermal).
- System engineering approach: identify and focus effort on critical issues or components only – wasting no time on details or solving symptoms.
- Effective communication (verbally or in to-the-point presentations or concisely written reports).
- Customer oriented, cost aware.
- Open minded, critical, creative and constructive attitude.
- Experience in all design phases: from concept design to final design, manufacturing support, testing and final acceptance / delivery.
