Laser Cooling and Spectroscopy of Relativistic C 3 + Beams at the ESR ∗

چکیده
We report on the first laser cooling of a bunched beam of multiply charged C ions performed at the ESR (GSI) at a beam energy of E = 1.47GeV. Moderate bunching provided a force counteracting the decelerating laser force of one counterpropagating laser beam. This versatile type of laser cooling lead to longitudinally space-charge dominated beams with an unprecedented momentum spread of ∆p/p ≈ 10−7. Concerning the beam energy and charge state of the ion, the experiment depicts an important intermediate step from the established field of laser cooling of ion beams at low energies toward the unique laser cooling scheme proposed for relativistic beams of highly charged heavy ions at SIS 300 (FAIR).

Laser cooling of relativistic C ions at the ESR
Recent experiments [1,2] at the Experimental Storage Ring (ESR) at GSI have shown that relativistic Li-like carbon (C) ion beams can be laser-cooled to an unprecedented momentum spread of p/p 10. Here, a single-frequency laser was tuned to the Doppler-shifted 1s2s 1s2p (P1/2 and P3/2) transitions. These results encourage the application of laser cooling to beams of other Liand Na-like ions at e...

The cooling of molecules during the adiabatic expansion of supersonic seeded molecular beams is reviewed and illustrated by the example of NO -molecules. The reduction of the Doppler width by collimation of the beam and the cooling to low rotational temperatures brings a significant simplification of the complex NO -absorption spectrum and allows its assignment. The measured rotational tem...

We propose the laser cooling of bunched relativistic beams of Alkaline-like and especially all Lithium-like ions in SIS 100/300, where due to the huge Doppler-shifts (γmax=35; Bρ=300Tm) optical ground state transitions can be excited employing existing laser technology. To avoid optical pumping between hyperfine levels e-e nuclei are preferred. The principle aim is the strong improvement of the...
متن کاملFrom laser cooling of non-relativistic to relativistic ion beams
Laser cooling of stored 24Mg ion beams recently led to the long anticipated experimental realization of Coulombordered ‘crystalline’ ion beams in the low-energy RF-quadrupole storage ring PAul Laser CooLing Acceleration System (Munich). Moreover, systematic studies revealed severe constraints on the cooling scheme and the storage ring lattice for the attainment and maintenance of the crystallin...
متن کاملEnergy Gain of Magnetized Cylindrical D-T Targets in Fast Ignition Fusion
In recent years, many different plans have been considered to use the nuclear energy gained from inertial confinement fusion (ICF) as attempts to obtain high energy efficiencies. In conventional ICF methods, a small amount (about mg) of the deuterium–tritium compound is confined in a small spherical chamber of a few millimeters in radius and compressed by laser or heavy ion beams with powers in...
