In view of the "fast track scenario" for the design and construction of DEMO partly in parallel to ITER, the option of employing high temperature superconductors and operating the high field toroidal magnets in the liquid nitrogen temperature range is presently under serious consideration. We will report on a study of some currently available industrial conductors, which were analyzed with respect to their current carrying capability in the temperature and field range of relevance to DEMO, issues of conductor homogeneity over the long lengths required for this purpose, their response to the expected fast neutron fluence as well as issues of critical current anisotropy. We will show that this application target is not out of reach, but that substantial research and development programs will be needed to achieve it.
