Daly detector
Detector consisting of an off-axis conversion dynode, scintillator, and photomultiplier. The dynode at high potential emits secondary electrons when ions impinge on the surface. The secondary electrons are accelerated onto the scintillator that produces light that is then detected by the photomultiplier detector, which can be outside the vacuum system.
