Radiation Resistant Magnets for the Super-FRS of the FAIR Project

The radioactive dose rate in the area behind the target of the Super-Fragmentseparator (Super-FRS) will be so high that most organic materials will be destroyed in a short period of time. After 20 years of operation, an accumulated dose of more than 280 MGy is expected at the most critical parts. Special magnets consisting of radiation resistant materials must be used. Three dipoles, three quadrupoles, and two sextupoles are required inside the target area. One prototype of a radiation resistant dipole already exists. This paper presents the design, installation analysis and tests carried out with the challenges encountered towards realization of the radiation resistant magnets to be employed in future.
