Abstract

A new electron scattering apparatus is developed based on concepts from the positron system built by Surko et al (1988). In an electron version of the system, the electron beam is provided by a cathode and the rest of the system is correspondingly modified to a simpler system. The system was tested by measuring electron scattering from argon to verify its operation. N₂O is important in the atmosphere and plasma processes, and in the intermediate energy region from 5 eV to 50 eV, there are two previous results for the electron scattering total cross-section which are in disagreement. We present here a new measurement for the total electron cross-section of N₂O, helping to resolve this disagreement.
