T2 Working Group Summary Report

The T2 Working Group has reviewed and discussed the issues and challenges of a wide range of magnet technologies: superconducting magnets using NbTi, Nb3Sn and HTS conductor with fields ranging from 2-15 T and permanent magnets up to 4 T. The development time of these technologies varies significantly, but all are considered viable, providing an unprecedented variety of choice that can be determined by a balance of cost and application requirements. One of the most significant advances since Snowmass '96 is the increased development and utilization of Nb3Sn. All of the current US magnet programs (BNL, FNAL, LBNL, and Texas A and M) have programs using Nb3Sn. There are also active programs in HTS development at BNL and LBNL. A DOE/HEP sponsored program to increase the performance and reduce the cost of Nb3Sn is in its second year. The program has already made significant advances. The current funding for this program is $500k/year and an increase to $2M has been proposed for FY02
