Abstract
A hybrid arrangement of more than one electron energy conversion mechanism in an electron detector is arranged such that an image can be acquired from both energy converters so that selected high-illumination parts of the electron beam can be imaged with an indirectly coupled scintillator detector and the remainder of the image acquired with the highsensitivity/direct electron portion of the detector without readjustments in the beam position or mechanical positioning of the detector parts. Further, a mechanism is described to allow dynamically switchable or simultaneous linear and counted signal processing from each pixel on the detector so that high-illumination areas can be acquired linearly without severe dose rate limitation of counting and lowillumination regions can be acquired with counting.
