A superconducting saddle magnet of 4 T for the MHD generator has been designed and constructed. At first, the magnet was tested in an experimental cryostat with inner diameter of 320 cm. It took about 100 hours cooldown from room temperature to LHe temperature and the liquid helium inventory in cryo
0.04 x 2 x 5 mm 3 in size. A freshly deposited film has a high internal friction peak (curve I) at 55 K (vibration frequency 639 Hz), which moves along the temperature axis with changing frequency. The activation energy, determined from the shift of the curves is 0.072 eV. After annealing at 800 K f
