The key idea consists in the use of a broad-band laser, which, impinging transversely on the ion beam to be cooled, causes phase-space compression through resonance radiation pressure, Our technique, by allowing simultaneous resonant excitation of almost all ions regardless of their velocity, compensates for the short laser-ion interaction time and gives a very large capture range.

Abstract
We propose a method For a direct transverse laser cooling of ions in a storage ring and we discuss its application to Li-7(+) and (24)Me(+) ions studied in present storage rings. The key idea consists in the use of a broad-band laser, which, impinging transversely on the ion beam to be cooled, causes phase-space compression through resonance radiation pressure, Our technique, by allowing simultaneous resonant excitation of almost all ions regardless of their velocity, compensates for the short laser-ion interaction time and gives a very large capture range.File in questo prodotto:
