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 کاملCollisional Cooling of Negative Ion Beams
Managed by UT-Battelle, LLC, for the U.S. Department of Energy under contract DE-AC05-00OR22725. Abstract Investigations have been conducted to determine the feasibility of using collisional cooling for reducing the energy spreads and, consequently, the emittances of negative-ion beams. We have designed a gas-filled RFquadrupole ion cooler equipped with provisions for retarding energetic nega...
متن کاملEnhanced Optical Cooling of Ion Beams for Lhc
In original OSC with usage of quadrupole wiggler as a pickup [1], particles with small betatron amplitude do not make an input into signal generation (radiation), so they are not heating the beam. In contrast, in EOC method such selective action achieved by usage of movable screens. These screens located on image plane of optical system having radiating beam as source. Motion realized with the ...
