Pulsed electron lenses for space charge compensation in the FAIR synchrotrons

Abstract The FAIR heavy-ion synchrotrons SIS18 and SIS100 as part of the new FAIR accelerator facility at GSI will be operated at the “space charge limit” for light and heavy-ion beams. In SIS100 beam loss due to space charge induced resonance crossing should not exceed a few percent during the 1 s...

Summary:Abstract The FAIR heavy-ion synchrotrons SIS18 and SIS100 as part of the new FAIR accelerator facility at GSI will be operated at the “space charge limit” for light and heavy-ion beams. In SIS100 beam loss due to space charge induced resonance crossing should not exceed a few percent during the 1 s injection plateau. In order to further increase the beam intensities beyond the FAIR reference parameters, a new concept of (partial) space charge compensation by pulsed electron lenses is considered. We describe the general space charge compensation concept together with detailed simulations results. A prototype lens for SIS18 is presently under development and will be used to validate the concept. This new approach, aiming for mitigating the most prominent intensity limitation, should be applicable to many of the existing large scale proton and heavy-ion synchrotrons world wide.
