A single pole 6T s. c. wiggler with two racetracks NbTi superconducting coils, separated by a central plate and kept together by two iron jokes, has been designed and built in the Frascati INFN, LNF Laboratories in cooperation with the Ansaldo ABB Componenti, Genova, Italy. The s. c. magnet and two low field compensating warm poles, will be installed in the near future on the straight section no. 10 of the e+, e- storage ring Adone, to be used as wave length shifter to produce a hard X-ray flux of 2. 4 10¹2 photons/s/mrad in 0. 1% bandwith at a critical energy of 9 keV, six times higher than the one produced by the accelerator bending magnets. The magnet's characteristics and the cryogenic facility dedicated have been illustrated in previous papers 1, 2; this article will make an analysis of the tipical quench during the training.
