      abstract     = {The Engels polarization method, invented in September 2022
                      by Dr. R. Engels,offers an easy and reliable way to produce
                      hyperpolarization in particle beams, e.g.,hydrogen,
                      deuterium, $^3He^+$, etc.. This method draws inspiration
                      from the Sonamethod proposed by P. G. Sona in 1967. It
                      consists of two opposing magnetic fieldsto alter the total
                      angular projection of pure states in hydrogen-like atoms. In
                      thecase of the Engels method, the longitudinal magnetic
                      field forms a sinusoidal, whichprovides a quantization axis
                      and a zero crossing for the spin. Generating this
                      fieldrequires two solenoids with mirrored currents, which
                      must be placed in front ofeach other. Ramping their magnetic
                      field leads to oscillations in the photomultipliersignal.
                      These oscillations correlate to a change in the occupation
                      numbers of theZeeman states and have been the subject of
                      investigation at the Institute for NuclearPhysics (IKP) at
                      the Research Center Jülich (FZJ) for the past few years.
                      Theyare caused by transitions between the hyperfine
                      sub-states related to the radialmagnetic field oscillations
                      of the unit. This magnetic field component is proportionalto
                      the radial distance from the symmetry axis of the coils and
                      the derivative ofthe longitudinal component. In order to
                      study the effects of this orthogonal fieldcomponent, a new
                      transition device has been proposed. The new device needs
                      tohave a proper sinusoidal waveform, so two coil pairs with
                      opposite currents will beused. The offset for each coil to
                      the beam pipe, as well as the relative distancebetween the
                      coil pairs, can be changed in the new device. Details
                      regarding thedevice’s operation and the methods for
                      constructing a transverse transition unit areprovided in
                      this thesis, along with simulated data to approximate its
                      behavior.},
