Cryogenic distribution for radioactive secondary beam fragment separator (Super-FRS) of FAIR

We present the flow schemes for the superconducting dipoles, the superconducting multiplets (quadrupoles, hexapoles, octupoles and steering dipoles) and the corresponding feedboxes of the Super-FRS in the FAIR project. The system layout of the helium distribution for the whole separator including the three branches of the Super-FRS and the experiment caves is discussed as well. Based on the maximum cooling capacity specified for the refrigerator, the cold-down time of the multiplets which are characteristic of large cold mass (up to 37 Tons for each) has been investigated. The issues as operation conditions, quench protection and safety relief are also discussed.
