SIS 100 Main Magnets: Test Results and Operation Parameters
نویسندگان
چکیده
The FAIR accelerator complex will consist of several accelerator rings. The SIS100 synchrotron, the core component of this facility, will be the world’s second large scale synchrotron using superconducting magnets (dipoles: maximum field 2 T, repetitions frequency 1 Hz) targeted for accelerating high current ion beams (Uranium up to U). Based on thorough R&D [1], first full scale magnets were built [2, 3] with the first dipole already extensively tested and its operation parameters measured, including: the magnetic field [4, 5, 6] and the AC losses [7].

Testing the fast pulse operation of SIS12
During this experiment the magnet power supplies have been operated in SIS12 mode, so that a maximal current of 2.3 kA for the main SIS dipole magnets at a magnetic rigidity of 12 Tm was feasible. It had been clarified that a continuous operation would be possible up to an electric power of 5 MW, while for higher power an asynchronous single shot mode had been foreseen. Both SIS RF-cavities wer...
متن کاملSis100 Fast Ramped Magnets and Their Cryopump Functionality for the Operation with High Intensity Intermediate Charge State Heavy Ions
The FAIR SIS100 accelerator at GSI Darmstadt will be equipped with fast ramped superconducting magnets. The high current Uranium beam modes with intermediate charge states, require ultra low vacuum pressures which can be achieved in long term operation only by cold beam pipes acting as a cryopump with stable temperatures well below 15 K for all operating cycles. The straightforward layout for r...

The Large Hadron Collider, now under construction at CERN, relies heavily on superconducting magnets for its optics layout: besides the main magnets, almost all the correcting magnets are superconducting. Along with clear advantages, this brings about complications due to the effects of persistent currents in the superconducting filaments. Corrector magnets that trim key beam parameters or comp...
متن کاملNb Sn Accelerator Magnet Technology R & D at Fermilab
INTRODUCTION Nb3Sn accelerator magnets allow magnet operation above 10 T and drastically increase the coil temperature margin relative to NbTi magnets. Magnets with such parameters are needed for the LHC IR upgrade, cr mponents of ILC, MSR and MC magnet systems. Fermilab is developing Nb3Sn accelerator magnets using shell-type dipole coils and the wind-and-react method. The R&D program includes...
متن کاملIonization Beam Loss and Collimation in SIS18
Introduction Ionization of beam ions, especially at operation with intermediate charge states, combined with a strongly dynamic residual gas pressure may create major beam loss. The first experimental evidence has been obtained in SIS18 machine experiments in 2001 with U-ion beams. Operation with intermediate charge states is in general required to minimize the incoherent space charge tune shif...
