The close cycle cryostat (Janis, USA) with the accompanying spectrometer (SEECo, USA) allow verry efficient acquisition acquisition of temperature dependent Mössbauer spectra, down to 4.5 K over a large range of velocities and for different Mössbauer
isotopes (57Co, 119Sn and 151Eu). Static magnetic fields of 300 Oe and 600 Oe can be used. The spectrometers work both in the Mössbauer mode as well as in pulse amplitude mode, for a proper selection of the involved range of gamma ray energies.
