	The upgrade of the existing heavy ion synchrotron SIS18 as booster for the FAIR synchrotron SIS100 has been partly completed. With the achieved technical status, a major increase of the accelerated number of heavy ions could be reached. This progress especially demonstrates the feasibilty of acceleration of medium charge state heavy ions with high intensity and and the succesfull control of dynamic vaccuum effects and correlated charge exchange loss. Two further upgrade measures, the installation of additional MA acceleration cavities and the exchange of the main dipole power converter are in progress. For the FAIR synchrotron SIS100 all major components with long production times have been ordered. With several pre-series components, outstanding technical developments have been completed and the readiness for series production reached. The technical project status will be summarized.

WEPRI083	The SIS100 Superconducting Fast Ramped Dipole Magnet	2681
	E.S. Fischer, A. Bleile, J.P. Meier, A. Mierau, P. Schnizer GSI, Darmstadt, Germany P.G. Akishin JINR, Dubna, Moscow Region, Russia
	The first dipole magnet of the superconducting SIS100 accelerator was delivered by industry and its thermodynamic, electrical and magnetic field performance was measured. We describe the build of the test facility, the infrastructure and its performance, outline the chosen measurement methods along with the optimisation of the magnet end required for obtaining the requested integral field quality. The measured ac loss parameters will be discussed in respect of the possible operation performance of the whole machine, the relevant cooling conditions of the main dipole magnet.

	Superconducting heavy ion synchrotron SIS100 is the central accelerator of the FAIR accelerator complex. There are more than 10 types of the quadrupole units in SIS100 due to the combination of the quadrupoles from 3 families and several types of the corrector magnets. Magnetic field optimization of the quadrupole magnet ends including evaluation of cross talk between closely attached quadrupole and corrector magnets will be reported.
