Abstract:
1. A particle-optical device for irradiating an object with a beam of particles, comprising a housing in which are located positioning means for positioning the object within the housing, comprising a reference body supported against a supporting portion of the housing and a kinematic system holding the object and controllably move-able with respect to the reference body, for manipulating the object in at least one degree of freedom with respect to the reference body, and further comprising a control mechanism and at least one combination of a piezo-electric position actuator and a piezo-electric force sensor positioned in series, whereby the control means receives at least one input signal from at least one sensor and—generates a control signal for at least that actuator associated with the sensor, characterized in that the at least one combination is positioned between the housing and the reference body, the support of the reference body against the supporting portion of the housing occurring via said at least one combination wherein each actuator is clamped between, respectively, a first printed circuit body, in conducting contact with a first actuator pole of the actuator, and a second printed circuit body, in conducting contact with a second actuator pole of the actuator, which first printed circuit body and which second printed circuit body are in conducting contact with the control mechanism.
