Future experiments on hypernuclei γ-spectroscopy at FINUDA@DAFNE and PANDA@FAIR require the operation of germanium detectors in high magnetic fields ≈1T. To explore the feasibility of these experiments we studied the performance of high resolution germanium detectors of the VEGA and EUROBALL collaboration in a magnetic dipole field. We will present results on the energy resolution and the pulse shape as a function of the magnitude and the orientation of the magnetic field.
