We use a strongly interacting Rydberg sample to implement a spin 1/2 system composed of two different Rydberg levels. In order to accurately measure the global spin magnetization, we will implement a state selective field ionization scheme. This will be done by ramping an electrical field to temporally separate the ionization for different Rydberg levels. We will present first measurements of the ion signal from a micro-channel plate detector, calculations for the ionization probability of Rydberg atoms in a ramped electrical field and calculations of the ion trajectories. In the future, this technique will be used to study relaxation spin-dynamics and to test Thermalization in linear response theory.
