“…Followed by similar and more advanced experiments (see, e.g. [17,18,19,20,21]) collinear laser spectroscopy developed into a general technique for on-line investigations of spins, electromagnetic moments and nuclear charge radii of short-lived isotopes. It was continuously improved and combined with different detection techniques and, thus, became increasingly sensitive and accurate.…”

A high-voltage divider with accuracy at the ppm level and collinear laser spectroscopy were used to calibrate the highvoltage installation at the radioactive ion beam facility ISOLDE at CERN. The accurate knowledge of this voltage is particularly important for collinear laser spectroscopy measurements. Beam velocity measurements using frequencycomb based collinear laser spectroscopy agree with the new calibration. Applying this, one obtains consistent results for isotope shifts of stable magnesium isotopes measured using collinear spectroscopy and laser spectroscopy on laser-cooled ions in a trap. The long-term stability and the transient behavior during recovery from a voltage dropout were investigated for the different power supplies currently applied at ISOLDE.

“…For the potassium ions, ISCOOL operated with rf amplitude V rf = 280 V and Ω = 520 kHz, whereas for rubidium, V rf = 270 V and Ω = 450 kHz. The ion beam from ISCOOL were steered to the collinear laser spectroscopy beam line, COLLAPS [11][12][13]. Figure 2 shows a simplified scheme of the setup.…”

Abstract. A gas-filled segmented linear Paul trap has been installed at the focal plane of the high-resolution separator (HRS) at CERN-ISOLDE. As well as providing beams with a reduced transverse emittance, this device is also able to accumulate the ions and release the sample in bunches with a well-defined time structure. This has recently permitted collinear laser spectroscopy with stable and radioactive bunched beams to be demonstrated at ISOLDE. Surface-ionized 39,44,46 K and 85 Rb beams were accelerated to 30 keV, mass separated and injected into the trap for subsequent extraction and delivery to the laser setup. The ions were neutralized in a charge exchange cell and excited with a co-propagating laser. The small ion beam emittance allowed focussing in the ion-laser overlap region, which is essential to achieve the best experimental sensitivity. Fluorescent photons were detected by a photomultiplier tube as a frequency scan was taken. A gate (typically 7-12 μs wide) was set on the photomultiplier signal to accept the fluorescent photons within the time window defined by the bunch. Thus, using accumulation times of 100 ms, the dominant contribution to background due to continuous laser scattering could be reduced by a factor of up to 4 × 10 4 .

“…After extraction, acceleration to 50 kV and mass separation, the ions were delivered to the collinear laser spectroscopy setup [18]. This has been used for isotope-shift measurements on many elements down to neon (Z = 10) [19]. However, for very light elements the systematic uncertainties caused by the measurement of the acceleration voltage exceed the nuclear volume effect.…”
