Description

The cryostat with a commercial Gifford-McMahon cryocooler (RDK-415 from SHI)with a cooling power of 1.5 W at 4.2 K is installed in the room temperature bore of the 10 T conduction cooled superconducting magnet. The magnet consists of NbTi and Nb3Sn coils which are connected in series and charged with a single power supply. Magnetic field uniformity is 0.25% over the axial length of 30 mm. The magnet is cooled by a commercial two-stage 4 K Gifford-McMahon cryocooler (RDK-408 from SHI) with a cooling power of 1 W at 4.2 K. The total cold mass is 71 kg. Clear room temperature bore of the magnet is 80 mm. The magnetic system design and performance test results of a G-M cooler in magnetic field are presented.
