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: An environmental cell for a charged particle beam system allows relative motion between the cell mounted on an X-Y stage and the optical axis of the focusing column, thereby eliminating the need for a sub-stage within the cell. A flexible cell configuration, such as a retractable lid, permits a variety of processes, including beam-induced and thermally-induced processes. Photon yield spectroscopy performed in a charged particle beam system and using gas cascade amplification of the photoelectrons allows analysis of material in the cell and monitoring of processing in the cell. Luminescence analysis can be also performed using a retractable minor.

Abstract: A method of investigating a sample using a charged-particle microscope is disclosed. By directing an imaging beam of charged particles at a sample, a resulting flux of output radiation is detected from the sample. At least a portion of the output radiation is examined using a detector, the detector comprising a Solid State Photo-Multiplier. The Solid State Photo-Multiplier is biased so that its gain is matched to the magnitude of output radiation flux.

Abstract: A particle detector switchable from an ion detector to an electron detector includes an ion-to-electron converter and a scintillator detector. With one set of voltages on the components, the converter has minimal impact on the electron trajectories so the electrons are efficiently detected by the scintillator detector. With different voltage settings on the components, the detector can be operated in positive ion mode to collect positive ions with adequate efficiency for most FIB applications. The ion-to-electron converter is preferably in the shape of a cylinder or includes multiple parallel plates
