摘要： A method and apparatus for detection of charged particles in spectroscopy. Charged particles, received from an energy dispersive spectroscopic analyser as a charged particle beam, are accelerated towards a detector. The accelerated charged particles are received at an array of detecting pixels, the array of detecting pixels forming the detector. The charged particles arriving at the detector have a spread in the energy dispersive direction.
