Stability of Crystalline Ion Beams
نویسندگان
چکیده
In this paper, the conditions for which three-dimensional crystalline ion beams were attained in the rf quadrupole storage ring PALLAS at a velocity of around 2800 m/s are presented. The stability of these crystalline beams when subjected to discontinuous cooling is discussed for beams of different linear density and thus of different crystal structure. The survival time seems to only weakly depend on the linear density, in contrast to the heating of the beam after melting.

Experimental approaches to crystalline ion beams
Facing the difficulties associated with the preparation of crystalline ion beams in heavy ion storage rings we propose two complementary table top schemes to elucidate fundamental issues like stability criteria for moving ion crystals at low velocities. One is based on a small radio-frequency quadrupole (RFQ) storage ring, where by laser cooling Mg ion crystals at rest were observed, but concep...
متن کاملCrystalline Ion Beams in the RF Quadrupole Storage Ring PALLAS
We report on the crystallization of laser cooled Mg+ ion beams circulating in the table-top rf quadrupole storage ring PALLAS at a velocity of 2800 m/s (beam energy 1 eV). A sudden collapse of the transverse beam size and the low velocity spread clearly indicate the phase transition to a onedimensional linear string of ions. This crystalline beam shows exceptional stability, surviving for more ...
متن کاملThe quest for crystalline ion beams
The phase transition of an ion beam into its crystalline state has long been expected to dramatically influence beam dynamics beyond the limitations of standard accelerator physics. Yet, although considerable improvement in beam cooling techniques has been made, strong heating mechanisms inherent to existing high-energy storage rings have prohibited the formation of the crystalline state in the...
متن کاملCooling and heating of crystalline ion beams
The crystallization of ion beams has recently been established in the rf quadrupole storage ring PALLAS (PAul Laser CooLing Acceleration System) for laser-cooled 24Mg+ ion beams at an energy of about 1 eV. Yet, unexpectedly sharp constraints had to be met concerning the confinement strength and the longitudinal laser cooling rate. In this paper, related and up to now unseen heating mechanisms a...
متن کاملCrystallisation of ion beams in the rf quadrupole storage ring PALLAS
The crystallisation of laser-cooled Mg+ ion beams circulating in the table-top rf quadrupole storage ring PALLAS at a velocity of the order of 2800 m/s (beam energy 1 eV) is reviewed. Emphasis is given to the description of the experimental techniques that were required for this first realisation of crystalline beams. The equivalence of the equations of motion for rf electric and magnetic confi...
