Introduction
contact me: |
An NO2+ molecular
ion beam, produced by electron cyclotron resonance source (ECR), is crossed with a laser beam. The laser field causes the NO2+ ions to dissociate into
charged fragments. Voltages
applied to the spectrometer rings create an electric field, which causes
the fragments to accelerate towards a time- and position-sensitive
detector.This detector allows us
to make kinematically complete measurements; we can extract information
about the 3-D momentum vectors and kinetic energy of the fragments.
From this information, we hope to be able to deduce the
dissociation mechanisms of NO2+.
