 ABSTRACT

The calculations of transmission function of throchoidal electron spectrometer by numerical integration using the Monte Carlo method were performed. The calculations were made for different types of distributions of scattered electrons both for the interaction chamber only and for the model of entire spectrometer.  The result of each calculation was the count of detected electrons as a function of residual energy or scattering angle. Also, the effects due to finite size of apertures of the spectrometer were discussed. As a conclusion, the transmission function of a spectrometer was found to be generally proportional to the inverse of the scattered electrons residual energy (Er). This result was expected and is determined by the magnetic field and spectrometer geometry. However, particularly in the near threshold region, the transmission function becomes more complicated and dependent upon the angular distribution of scattered electrons. Additionally, the double throchoidal electron spectrometer, placed in the Laboratory for atom collisions, Faculty of Physics, Belgrade, was described.
