ASTM E983-2019 俄歇电子能谱学多余电子束效应最小化指南 Standard Guide for Minimizing Unwanted Electron Beam Effects in Auger Electron Spectroscopy

1.1 This guide outlines the origins and manifestations of unwanted electron beam effects in Auger electron spectroscopy (AES).

1.2 Some general guidelines are provided concerning the electron beam parameters which are most likely to produce these effects and suggestions are offered on how to minimize them.

1.3 General classes of materials are identified which are most likely to exhibit unwanted electron beam effects. In addition, a tabulation of some specific materials which have been observed to undergo electron damage effects is provided.

1.4 A simple method is outlined for establishing the existence and extent of these effects during routine AES analysis.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Dev
