Stationary electrode plates and a moving insulation sheet vary capacitance without friction, cutting power use and vibration-induced sensing errors.
Opposing main and adjustment bellows cancel retraction forces, enabling faster, finer vacuum capacitor capacitance control.
Active metal brazing and field-relaxing rings cut dielectric, hysteresis, and eddy-current heating in vacuum capacitor joints.
Placing the bearing on the atmosphere side lets the rotating capacitor be serviced without breaking vacuum, cutting accelerator downtime.
