The FAIR facility, under development at GSI, includes the synchrotron SIS300 (300 Tm rigidity). In order to reach the required high intensities of proton and heavy ions beams, the bending dipole magnets have to be pulsed from the injection magnetic field of 1.5 T up to 4.5 T maximum field at the rate of 1 T/s in a 100 mm diameter bore. The first 3.9 m long model dipole is in advanced construction and a functional test is foreseen at LASA Lab. This test will be performed inside a vertical cryostat in boiling helium at 4.2 K, and it is aimed to verify the operation of the magnet, also in pulsed regime, and to assess the losses. A final full characterization of the magnet will be performed later in a laboratory equipped for operation at the design conditions, i.e. supercritical helium at 4.7 K. This paper illustrates the design and the installation activity of the test station and its capabilities at LASA.
