Partial Laser Cooling and Saturation Spectroscopy on 9 MeV 7Li+ - Ions in a Storage Ring
1989
Publisher Summary Laser cooling and spectroscopy in traps have reached impressive perfections. This chapter discusses laser cooling and partially Doppler-suppressed spectroscopy on stored ions at 5.4% speed of light in the test storage ring (TSR) heavy ion storage ring in Heidelberg. It discusses the requirements for saturation spectroscpy with two counterpropagating collinear laser beams. In contrast to Penning and RF-traps, the ions in a storage ring move at a high longitudinal velocity with small transverse harmonic oscillations around the central orbit with just a few times the orbiting frequency in the case of strong focussing. However, the injection of the high velocity beam introduce…
Determination of Qβ values from endpoint energies of beta spectra
1979
Abstract A plastic scintillator telescope is described for determining beta endpoint energies up to 15 MeV. The response function of the telescope was measured using monoenergetic electrons from a betatron. A nonlinear procedure for unfolding the measured beta spectra on the basis of the experimental response function was tested successfully.
