摘要:
A secondary particle detector 302 for a charged particle beam system 300 includes a scintillator 304 and a transducer 312, such as a photomultiplier tube, positioned within a vacuum chamber 107. Unlike prior art Everhart-Thornley detectors, the photomultiplier is positioned within the vacuum chamber, which improves detection by eliminating optical couplings and provides flexibility in positioning the detector.
