The specialized mass-spectrometer for archaeological gold dating by radiogenic helium traces

The determinations of the mass spectrum, the charge and energy spectra of heavy particles and electrons emitted by solids when they are acted upon by particle and laser beams are effective method in studying physicochemical properties of solids. The paper considers the possibility of developing combined high energy resolution electron and mass spectrometers for research into solids. The spectrometers must have a relative high energy resolution. The device consists of a particle (ions and electrons) source converting particle energy spectrum into the mass spectrum, and energy analyzer with two-dimensional electrostatic field and plane of symmetry. The sources of beams exciting the surface of the sample under study are independent and not considered in the paper. The mathematical simulation of the device performance confirms the realizability of the method suggested.
