Abstract: A novel detector for a charged particle beam system which includes multiple gas amplification stages. The stages are typically defined by conductors to which voltage are applied relative to the sample or to a previous stage. By creating cascades of secondary electrons in multiple stages, the gain can be increased without causing dielectric breakdown of the gas.

Abstract: The gas filled in an envelope contains nitrogen and hydrogen. The nitrogen used as a supplementary gas is not polymerized even when radiation is applied to it, and serves to achieve higher resolution than in the case where carbon dioxide is used as the supplementary gas. The hydrogen can reduce the change of gas gain.

Abstract: The invention relates to a radiation detector, an arrangement and a method for an energy-dispersive detection of X-ray photons. X-ray photons are allowed to collide (701) in the radiation detector (201, 601), whereby there are produced (702, 703, 704, 705, 706, 707, 708) observations of the X-ray photons that collided in the detector. According to the invention, there are separately produced observations of X-ray photons (702, 703, 704) that collided in the first detector space (205, 501) of the radiation detector and X-ray photons (705, 706, 707, 708) that collided in the second detector space (206, 502) of the radiation detector. The (712) observations of X-ray photons that collided in the first detector space (205, 501) are ignored, when there is received a simultaneous observation of an X-ray photon that collided in the second detector space.
