Abstract :
Several different shell type coils were made by using the ´wind-and-react´ technique, installed in a mirror magnet configuration and tested at Fermilab. The results revealed that the previously suspect splice technique is adequate and is not responsible for the quench performance limitation. Cable instability is the preferred candidate, however this might be coupled with other effects since all of the experimental results cannot be explained exclusively with cable instability.
