Energy-Loss Dependence of the Ion-Induced Desorption Yield Measured with Ar10+ Ions at GSI-HHT
In heavy ion synchrotrons like SIS 18 high energetic ions can impact on the beam pipe and release gas molecules. This so called ”ion induced desorption” deteriorates the accelerator vacuum and, as a consequence, the beam life time and luminosity. Desorption yields η (released gas atoms or molecules per incident ion) of various materials have been studied at GSI since 2003. A scaling of the deso...
متن کاملTransverse BIF Profile Monitor - System Development for FAIR
The planned facility for antiproton and ion research FAIR at GSI will accelerate high intensity beams from protons to Uranium ions in the energy range of 100 MeV/u to 30 GeV/u. In the transport lines between the synchrotrons and in front of production targets precise alignment is required. Conventional intercepting diagnostics will melt due to the beam energy deposition. For transverse profile ...
متن کاملFocusing giga-electronvolt heavy ions to micrometers at the Institute of Modern Physics.
To study the radiation effect of cosmic heavy ions of low fluxes in electronics and living samples, a focusing heavy ion microbeam facility, for ions with energies of several MeV/u up to 100 MeV/u, was constructed in the Institute of Modern Physics of the Chinese Academy of Sciences. This facility has a vertical design and an experiment platform for both in-vacuum analysis and in-air irradiatio...
متن کاملModel Calculations of Ion Induced Desorption Yields
The ion induced desorption is a severe luminosity limitation for low charge state heavy ion accelerators. Thus it was intensively investigated in dedicated experiments during the last years. It was shown that the ion induced desorption is a surface effect with a strong link to the substrate [1]. The overall quantity of desorbed gas during long term irradiation is always in the range of a monola...
متن کاملExperimental Investigation of Impact-Induced Molecular Desorption by 4.2 MeV/u Pb Ions
In preparation for the heavy ion program of the LHC [1], accumulation and cooling tests with lead ion beams have been performed in the LEAR storage ring [2]. These tests have revealed that due to the unexpected, large outgassing of the vacuum system, the dynamic pressure of the ring could not be maintained low enough to reach the required beam intensities. To determine the actions necessary to ...
