	Novel experiments to study fundamental properties of high-energy-density states in matter generated by intense heavy ion beams will be carried out by the HED@FAIR collaboration at FAIR. For strong transverse focusing a special final focus system consisted of four superconducting large-aperture high-gradient quadrupole magnets will be installed at the end of the HED@FAIR beam line. Design and main characteristics of the quadrupole are discussed. Stress - strain dependence of the quadrupole superconducting cable and electrical strength of the cable insulation are measured. Results of mechanical and thermal calculation of main parts of the quadrupole are presented.

	The possibility of production of the coils based on high-temperature superconductors (HTS) for accelerator applications is now under preliminary study in many accelerator centres and laboratories. The alternating magnetic field in these magnets causes an energy dissipation (AC losses). The accurate measurement of AC losses is important for a comparison choice among different HTS conductors and for estimations of the total level of losses into final magnet too. This article presents the measurement of transport AC losses (i.e. the losses in magnetic field which is generated by the alternating transport current) in HTS coils. Two model HTS coils with the racetrack geometry have been fabricated from 2nd generation HTS conductor supplied by two vendors. The measurement was performed by electrical method at the sinusoidal current with the amplitude up to 32 A and at the frequencies lain into interval from 5 up to 100 Hz. The measurement scheme and results are presented.

Superconducting wide aperture high gradient quadrupoles for final focusing system of the HEDgeFAIR beamline are developed in fame of the collaboration between FAIR and NRC "Kurchatov Institute" - IHEP. Before the shipment to FAIR all manufactured quadrupoles are need to pass Factory Acceptance Tests including cold tests to ensure that they are complied with specifications. Test facility for cold test of these quadrupoles is created at NRC "Kurchatov Institute" - IHEP. This presentation gives information about design and main characteristics of the test facility.
