Enhancing the extraction of laser-ionized beams from an arc discharge ion source volume

α -decay branching ratio of Pt180

“…process in the VADLIS [15,16] in order to selectively ionize the mercury atoms of interest. The ions were extracted and accelerated by a 30-kV potential difference, and separated according to their mass-to-charge ratio by the ISOLDE general purpose separator.…”

“…The currently accepted value b α ( 180 Pt) ≈ 0.3% came from a study by Siivola [5], in which 180 Pt was produced in 16 O + 170,172 Yb, 19 F + 169 Tm, and 20 Ne + 162 Er fusion-evaporation reactions. The b α values for several platinum isotopes were deduced by comparing measured α-decay intensities to expected production yields, based on similar heavy-ion reactions studied in the rare-earth region.…”

First laser ions at the CERN-MEDICIS facility

“…for 169 Er) or by developing an ion source configuration, which should be adapted for a high ion flux operation, e.g. [29].…”

QEC -value determination for Na21→Ne21 and Karthein1, Atanasov2, Blaum3 et al. 2019Phys. Rev. C

“…In order to enable re-acceleration to 30 keV and magnetic mass separation using the general-purpose separator (GPS), the sodium and neon nuclides were ionized using the recently developed versatile arc discharge and laser ion source (VADLIS) [21,22] in its electron-impact ionization mode. The magnesium ions were selectively ionized using ISOLDE's resonant ionization laser ion source (RILIS) [23] while the VADLIS was used in a special surface-ion suppressing mode [22,24]. The high-precision mass spectrometer ISOLTRAP [25][26][27], schematically depicted in Fig.…”
