Abstract
A velocity map imaging setup has been designed and fabricated at the Max Planck
Institute for Nuclear Physics in Heidelberg to study multiphoton ionization. This
setup is placed in an optical cavity to amplify a frequency comb used to generate
the photoelectrons. A rotatable wave plate can be used to change the polarization of
the laser, by changing the polarization it is possible to view the electron momentum
distribution from different angles. In this work, first measurements with this setup were
investigated, and the resulting electron momentum distribution was reconstructed as
a 3D model using the Abel transform and computed tomography.
