The SIS100 is the core component of the FAIR accelerator complex. It will be the largest fast ramped synchrotron for heavy ion research using superconducting magnets.
Starting from the design of its ancestor the Nuclotron in JINR Dubna we accomplished an intensive R&D process to develop magnets fulfilling the ambitious requirements for SIS100 operation concerning field quality, cycling frequency, cryogenic losses and reliability. In addition the beam pipe has to operate as a cryopump to reach extremely low vacuum pressures.
We describe the different design modifications required to minimise the AC losses as well as to get a better field quality. We show the current vacuum chamber design and present the measurements result obtained for the first prototype dipole.
