Impedance and Instability Studies in LEIR with Xenon
In 2017, the LEIR accelerator has been operated with $Xe^{39+}$ beam for fixed target experiments in the SPS North Area. The different ion species, with respect to the standard $Pb^{34+}$, allowed for additional comparative measurements of tune shift versus intensity at injection energy both in coas...

| description | In 2017, the LEIR accelerator has been operated with $Xe^{39+}$ beam for fixed target experiments in the SPS North Area. The different ion species, with respect to the standard $Pb^{34+}$, allowed for additional comparative measurements of tune shift versus intensity at injection energy both in coasting and bunched beams. The fast transverse instability observed for high accumulated intensities has been as well characterized and additional observations relevant to impedance have been collected from longitudinal Schottky signal and BTF measurements. The results of these measurements are summarised and compared to the currently developed machine impedance model. |
