Study Of Neon Collisional Negative Ion Compound Resonance Using A Trochoidal Electron Monochromator, Will Brunner

Honors Theses

This thesis describes the experimental apparatus and procedure used to measure the excitation function of the 2p⁵3p ³D₃ state of neon. First I describe the effect on this excitation of negative ion resonances and previous experiments to measure the excitation function, as well as suggestions for future applications of such studies. Then the experimental apparatus is described in three parts. The vacuum system uses a turbomolecular pump to decrease the pressure of the chamber to as low as 4*10^-9 Torr. The electron beam system incorporates a trochoidal electron monochromator to send a highly monochromatic beam …
