Sub-millimetre wall thickness is foreseen for the vacuum tubes in the magnets of the superconducting dipoles of the SIS100 and SIS300 of the FAIR Project. The Bragg peak of the energy deposition by the U ions in these walls may lie dangerously close to the superconducting cables. Thus the precise knowledge of the dE/dx profile is essential for estimating(More)
The paper studies the method active constellation extension (ACE) for increasing the channel capacity of orthogonal frequency-division multiplexing (OFDM) with a nonlinear power amplifier at the transmitter. It turns out that ACE is able to optimize the capacity but at the expense of an increased out-of-band radiation. In order to solve this issue, ACE is(More)
The planned International Facility for Antiproton and Ion Research (FAIR) will consist of a superconducting double-ring synchrotron offering ion beams of intensity increased by a factor of 100-1000 compared to the existing GSI accelerators. Materials close to the beam tube will be exposed to secondary radiation of neutrons, protons, and heavier particles,(More)
Radiation damage to various elements of the cosθ-type dipoles of the SIS300 synchrotron of the FAIR Project was calculated. Among the elements under consideration were the superconducting cable, insulating materials, and high-current by-pass protection diodes. The Monte-Carlo particle transport codes MARS and SHIELD were used to simulate propagation of(More)
Various processes related to the beam dynamics can cause the beam halo formation which is one of the reasons for uncontrolled beam losses. The beam losses interact with the accelerator structure and can cause various problems such as: vacuum degradation due to desorption process, superconducting magnets quenches, activation of the accelerator structure,(More)
Quantification of the residual activity of accelerator structures due to beam-losses during normal operation is an important issue for existing (SNS or RHIC) and planned (LHC or FAIR) high-energy accelerator facilities. The activation of accelerator structures is already an intensity limiting problem. While beam-losses of 1 W/m for proton machines is(More)
Within the frame of the EuCARD [1] program, the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt is performing accelerator R&D in workpackage 8: ColMat. The coordinated effort is focussed on materials aspects important for building the FAIR accelerator facility [2] at GSI and the LHC upgrade at CERN. Accelerator components and especially(More)
The FAIR project planned at G.S.I. (Germany) requires the construction of several superconducting accelerator rings. One of the two synchrotron rings, named SIS300, will have dipoles with a central field of 6 T and a ramp rate of 1 T/s. In order to protect these fast-ramping magnets in case of a quench, each of them must be equipped with a diode stack that(More)
