Thesis (MSc (Physics))--Stellenbosch University, 2009. / ENGLISH ABSTRACT: This thesis aims to comprehensively discuss ultrafast electron di raction and
its role in temporally resolving ultrafast dynamics on the molecular level. Theory
on electron pulses and electron pulse propagation will be covered, but the
main focus will be on the method, equipment and experimental setup required
to generate sub-picosecond electron pulses, which are needed to perform time
resolved experiments. The design and construction of an electron gun needed
to produce the electron pulses will be shown in detail, while preliminary pulse
characterization experiments will also be illustrated. An introduction into the
theory of electron diffraction patterns and how to interpret these diffraction
patterns will conclude the thesis. / AFRIKAANSE OPSOMMING: Hierdie tesis het ten doel om ultravinnige elektrondi raksie deeglik te bespreek
asook die rol wat dit speel om ultravinnige tyd-dinamika op 'n molekulêre vlak
op te los. Die teorie van elektonpulse en die voortplanting van elektronpulse sal
gedek word, maar die fokus sal op die metode, gereedskap en eksperimentele opstelling
wees wat benodig is om sub-pikosekonde elektronpulse te genereer. Die
ontwerp en konstruksie van 'n elektrongeweer, wat benodig word om elektronpulse
te produseer, sal in detail bespreek word, terwyl aanvanklike pulskarakterisasie
eksperimente ook illustreer sal word. 'n Inleiding tot die teorie van
elektrondi raksie patrone en hoe om hulle te interpreteer sal die tesis afsluit.
