The stability of advanced Nb3Sn wires with CuNb reinforcing stabilizer cooled by refrigerator is studied in order to obtain data base for the future compact design of cryocooled superconducting magnets. The experiments on the critical currents, the minimum quench energy and the normal zone propagation velocity for a cryocooled sample-coil of the CuNb/Nb3Sn wires are carried out under the condition of the magnetic field up to 15 T at temperatures ranging from 4 K to 10 K. Added to this, we make a comparison between the stability of CuNb/Nb3Sn and Cu/Nb3Sn wires in the cryocooling case. It is concluded from this experimental result there are the slight differences between two kinds of wires, which have to be considered for cryocooled magnet design.
