Abstract [en]
This project studies the energy resolution and nuclear charge resolution of an ionization chamber (IC) setup connected to the Lohengrin Mass-Spectrometer ahead of a fission yield experiment on Uranium 233. The energy resolution of the IC was found to be EFWHM = 640(2) keV at Ekin = 90 MeV (mass A = 90). For isotopic separation, two different foil stacks were tested. The two stacks were found to achieve a worst case nuclear charge resolution of Z/δZ = 40 for Z = 37 and Z/δZ = 45 for Z = 39, respectively. However, the poor energy resolution of the second stack makes the first foil a better choice. The achieved nuclear charge resolution with this foil should be sufficient for the lighter masses which are to be studied in the upcoming fission yield experiment.
