Abstract

Transverse coherent instability of a bunch in a ring accelerator is studied with space charge and short wake field taken into account. It is assumed that space charge tune shift significantly exceeds the synchrotron tune. The bunch spectrum, instability growth rate and effects of chromaticity are studied over a wide range of parameters. Fast instability caused by coupling of transverse modes is studied as well. It is shown that, for monotonic wakes, the TMCI is possible only with certain sign of the wake. Its threshold is calculated precisely for different bunch and wake forms.

Transverse modes and instabilities of a bunched beam with space charge and resistive wall impedance

Journal Article Balbekov, V ; /Fermilab - Physical Review Special Topics - Accelerators and Beams

Transverse instability of a bunch in a ring accelerator is considered with space charge and wakefield taken into account. It is assumed that space charge tune shift significantly exceeds the synchrotron tune. Bunch spectrum, instability growth rate, and effects of chromaticity are studied with different bunch and wake forms. Fast instability caused by coupling of transverse modes is studied in detail. It is shown that, for monotonic wakes, the transverse mode coupling instability is possible only with a certain sign of the wake. Its threshold and growth rate are calculated precisely over a wide range of parameters.

Convective instabilities of bunched beams with space charge

Journal Article Burov, A. - Physical Review Accelerators and Beams

For a single hadron bunch in a circular accelerator at zero chromaticity, without multiturn wakes and without electron clouds and other beams, only one transverse collective instability is possible, the mode-coupling instability (TMCI). For sufficiently strong space charge (SC), the instability threshold of the wake-driven coherent tune shift normally increases linearly with the SC tune shift, as independently concluded by several authors using different methods. This stability condition has, however, a very strange feature: at strong SC, it is totally insensitive to the number of particles. Thus, were it correct, such a beam with sufficiently strong SC, being stable atmore »« less

Transverse mode-coupling instability and space charge

Journal Article Zolkin, T. ; Burov, A. ; Pandey, B. - Physical Review Accelerators and Beams

Transverse mode-coupling instability (TMCI) is known to limit bunch intensity. Since space charge (SC) changes coherent spectra, it affects the TMCI threshold. Generally, there are only two types of TMCI with respect to SC: the vanishing type and the strong space charge (SSC) type. For the former, the threshold value of the wake tune shift is asymptotically proportional to the SC tune shift, as it was first observed twenty years ago by M. Blaskiewicz for exponential wakes. For the latter, the threshold value of the wake tune shift is asymptotically inversely proportional to the SC, as it was shown bymore »« less

Transverse mode coupling instability threshold with space charge and different wakefields

Journal Article Balbekov, V. - Physical Review Accelerators and Beams

Transverse mode coupling instability of a bunch with space charge and wake field is considered within the frameworks of the boxcar model. Eigenfunctions of the bunch without wake are used as a basis for the solution of the equations with the wake field included. A dispersion equation for constant wake is presented in the form of an infinite continued fraction and also as the recursive relation with an arbitrary number of the basis functions. Realistic wake fields are considered as well including resistive wall, square, and oscillating wakes. It is shown that the TMCI threshold of the negative wake growsmore »« less

TMCI and Space Charge

Journal Article Zolkin, T. ; Burov, A. - TBD

Transverse mode-coupling instability (TMCI) is known to limit bunch intensity. Since space charge (SC) changes the spectra of the collective modes, it affects the TMCI threshold as well. In agreement with results of M. Blaskiewicz and V. Balbekov, we found that, when the wake is negative or it essentially negative, the instability threshold increases as fast as the space charge tune shift when the latter is large enough. In contrast, for oscillating wakes, when the oscillations are sufficiently pronounced, the threshold dependence on SC is non-monotonic; at sufficiently high SC tune shift the threshold goes inversely proportional to that.
