Abstract

The properties and characteristics of the trochoidal monochromator, improved by Stamatovic and Schulz for producing low-energy monoenergetic electrons, are investigated by means of a method of calculation of the electron energy distribution. By assuming that the angular divergence of the incident beam is approximately 10°, the calculated energy distribution has a half-intensity width of 0.015 eV compared to 0.02 eV measured by Stamatovic and Schulz. Further calculations show that by changing some of the operating conditions it is possible to gain either an improvement of about 35% in the resolving power for the same transmission, or an improvement up to 100% in the transmitted current intensity for the same resolving power.
