Some problems encountered with high-power targets with special reference to neutrino factories

An outline is given of the general problems of high-power targets used in particle accelerators with cw and pulsed beams for a variety of uses, such as neutron and radioactive particle production and in particular for pion production in neutrino factories. The question of heat dissipation and thermal shock with pulsed beams will be examined along with those of the target station, remote handling, replacement of components and maintenance. A discussion of the facilities that may be needed to address these issues and the required R&D will be presented.
