“…A laser ion source based on a gas cell has been proposed by van Duppen and coworkers [88] and demonstrated at the Leuven Isotope Separator on-line (LISOL) [89,90]. A development of an on-line gas-cell laser ion source is going on at Jyväskylä [91] and is also foreseen at RIKEN (Rikagaku Kenkyusho, Institute of Physical and Chemical Research, Japan) [92] and for the next-generation facility FAIR at GSI Darmstadt (Facility for Antiproton and Ion Research).…”

Atomic physics techniques for the determination of ground-state properties of radioactive isotopes are very sensitive and provide accurate masses, binding energies, Q-values, charge radii, spins, and electromagnetic moments. Many fields in nuclear physics benefit from these highly accurate numbers. They give insight into details of the nuclear structure for a better understanding of the underlying effective interactions, provide important input for studies of fundamental symmetries in physics, and help to understand the nucleosynthesis processes that are responsible for the observed chemical abundances in the Universe. Penning-trap and and storage-ring mass spectrometry as well as laser spectroscopy of radioactive nuclei have now been used for a long time but significant progress has been achieved in these fields within the last decade. The basic principles of laser spectroscopic investigations, Penning-trap and storage-ring mass measurements of short-lived nuclei are summarized and selected physics results are discussed. † going to cryogenic temperatures, or enhancing the induced signal by using higher charge states and/or longer accumulation times. Ideal applications for this method are mass measurements of super-heavy element (SHE) isotopes for nuclear structure studies as they are performed at SHIPTRAP [25,26]. SHE are produced in minuscule quantities, and typically have half-lives of hundreds of milliseconds to a few seconds. A proof-ofprinciple experiment is planned at the TRIGA reactor facility TRIGA-TRAP at Mainz University [27] and applications for HITRAP with highly charged ions are foreseen [28]. Requirements for Mass Measurements of Radioactive IonsThe specific requirements for the mass measurements of radioactive ions stem from the parameters of the ions themselves. For example the required sensitivity (depending on the production yield) and measurement speed (depending on the half-life) as well as the envisaged application which dictates the required precision. In order to be meaningful, all measurements should deliver reliable data, hence precise and accurate. The physics requirements can be categorized with the corresponding relative precision as follows:• nuclear structure, δm/m ≈ 1 × 10 −7• nuclear astrophysics, δm/m ≈ 1 × 10 −7/−8 • test of fundamental symmetries, neutrino physics, δm/m ≈ 1 × 10 −8/−9

We propose an ultra trace analysis approach for 26 Al by high-resolution Resonance Ionization Mass Spectrometry (RIMS) using a pulsed narrow band-width Ti:Sapphire laser. For ensuring efficient ionization and high isotopic selectivity in RIMS of Al, we developed an injection seeded pulsed Ti:Sapphire laser with high repetition rate operation at up to 10 kHz. The laser produced an output power of 2 W and a spectral band-width of $20 MHz with a repetition rate of 7 kHz. A first demonstration of its performance was done by detecting stable 27 Al using RIMS.

“…Following a three-step excitation scheme into an auto-ionizing state [29], a beam of 180,000 99 Tc ions per second was generated by the LIS. The contribution of the non-photo-ionized background of 99 Tc was suppressed by a factor of 56 in this demonstration measurement [15].…”

“…At a typical line width of 2-5 GHz and with pulse lengths around 25 ns [14], up to 2.5 W energy can be attained. At an advanced evolution stage, more than 6 W have been achieved by double-sided pumping of the Ti:Sa crystal lately [15]. By subsequent conversion into higher harmonics via single-pass transmission through non-linear crystals, the fundamental Ti:Sa laser light can be frequency doubled (%200 mW), tripled and quadrupled (both %20 mW).…”
