متن کاملSpatial Compression of Bunched Crystalline Ion Beams
Recently, bunched crystalline ion beams have been realized in the table-top rf quadrupole storage ring PALLAS by means of laser cooling. Here, a novel method for the measurement of the spatial distribution of the ion bunch is presented which is based on the time-resolved analysis of the fluorescence emitted by the ions during cooling. Thus, the phase transition from a gaseous to a crystalline b...
متن کاملSpectral Analysis of Relativistic Bunched Beams
Particles in a storage ring are oscillating in the longitudinal and transverse dimensions, and therefore, the frequency domain is natural for analyzing many beam generated signals. Information ranging from oscillation frequencies to beam phase space distributions can be extracted from the spectral content of these signals. It is often necessary to switch between time and frequency domains using...
متن کاملEquilibrium and Confinement of Bunched Annular Beams
The azimuthally invariant cold-fluid equilibrium is obtained for a periodic, strongly bunched charged annular beam with an arbitrary radial density profile inside of a perfectly conducting cylinder and an externally applied uniform magnetic field. The selfelectric and self-magnetic fields, which are utilized in the equilibrium solution, are computed self-consistently using an electrostatic Gree...
متن کاملStructural changes in bunched crystalline ion beams
Measurements of the spatial distribution of bunched crystalline ion beams in the radio frequency quadrupole storage ring PALLAS are presented for different ratios of the longitudinal and the transverse confinement strengths. The length of highly elongated crystalline ion bunches and its dependence on the bunching voltage is compared to predictions for a one-dimensional ion string and three-dime...
