    摘要: An electromagnetic wakefield detector placed in close proximity to a design trajectory of a non-relativistic charged particle beam produces an optical signal in response to passage of the charged particle beam without interrupting the charged particle beam. A photon detector receives the optical signal and produces a corresponding output. The wakefield detector may be based on the electro optic effect. Specifically, the detector may measure the effect of the charged particle beam a beam of radiation on the phase of radiation travelling parallel to the beam in a nearby electro optic waveguide.

A source that emits electrons is positioned within the first vacuum chamber. A beam-limiting aperture is configured to pass a limited angular range of the emitted electrons. A magnetic immersion lens is positioned outside of the first vacuum chamber and is configured to immerse the electron source in a magnetic field so as to focus the emitted electrons into the primary electron beam. An objective lens is configured to focus the primary electron beam onto a beam spot on a substrate surface so as to produce scattered electrons from the beam spot. Controllable deflectors are configured to scan the beam spot over an area of the substrate surface.

The probe assembly comprises a plurality of probes (30) arrayed across a plane on a mount, each probe comprising at least two elongate, electrically conductive elements (32, 33, 34) arranged such that their respective elongate directions make a non-zero angle with one another in the plane of the array. The beam deflection control module is adapted to control the deflection of the charged particle beam along a measurement path which crosses sequentially at least two of the elongate, electrically conductive elements of at least one of the probes. The detection module is connected to the electrically conductive elements of each of the plurality of probes, and is adapted to detect electric signals output sequentially by the electrically conductive elements of each probe upon intersection of the charged particle beam therewith. The detected electric signals from each probe are indicative of properties of the charged particle beam when directed to the location of the respective probe across the probe assembly by the charged particle beam generator. A corresponding method of measuring properties of a charged particle beam output by a charged particle beam generator is also disclosed.
