 Abstract: A critical parameter of mass spectrometry is the magnetic field and its uncertainty during the measurement process. Therefore a stabilisationsystem is build which protects the PENTATRAPPenning trap against external magnetic field fl uctuations like the drift of the earth magnetic field. For the existing control electronics a Helmholtz coil is build and characterized. The characterization includes measurements of the axial and radial magnetic field and the current-to-field curve in the center of the coil. The system is installed for a test of principle. The proportionality factor between the measured field and the current through the Hemlholtz coils is adjusted to −1. In addition the shielding factor is measured to estimate the distortions of the magnetic field inside the magnet.
