| Summary: | The invention provides a charged particle beam device for irradiating a specimen, comprising a particle source for providing a beam of charged particles, an optical device for directing the beam of charged particles onto the specimen and an ozone unit for reducing the charging and/or contamination of the specimen. The ozone unit comprises a supply of ozone and a specimen nozzle unit for directing an ozone gas flow to the specimen. Further, the invention provides a charged particle beam device for irradiating a specimen comprising a particle source for providing a beam of charged particles, an optical device for directing the beam of charged particles onto the specimen, a detector and a gas unit for reducing the charging and/or contamination of the detector. The gas unit comprises a supply of gas and a detector nozzle unit for directing a gas flow to the detector. Further, the present invention provides methods for operating charged particle beam devices according to the present invention. |
