Submitted

For high-precision gamma-ray measurements (e.g. 0+ - 0+ beta decay)we are about to calibrate a HPGe detector in efficiency. The aim is to obtain an efficiency curve with an uncertainty at the 0.1% level over a range of energy from 100 keV to 6 MeV. Standard source measurement, online source measurement taken at ISOLDE and several scans of the detector are combined to adjust the geometrical...

26. Neutron Wall: recent results and future plans

Johan Nyberg (Uppsala University)

Submitted

The Neutron Wall is a compact 1π neutron detector array consisting of 50 liquid scintillator detectors. The array has been used together with the EUROBALL gamma-ray spectrometer at INFN-LNL in Italy and at IReS in France. Presently it is located at GANIL where it is combined with EXOGAM in experiments with both stable and radioactive ion beams. Recent results obtained with the setup at GANIL...

22. Laser Spectroscopy with the Leuven gas cell-based Laser Ion Source

Dr Rafael Ferrer-Garcia (IKS-KULeuven)

07/12/2011, 09:40

Submitted

The Leuven Isotope Separator Online (LISOL) facility, located at the Cyclotron Research Center (CRC), Louvain- la-Neuve, is a successful producer of purified rare ion beams using resonant laser ionization of reaction products thermalized in a buffer-gas cell. After almost two decades of operation high purity radioactive ion beams of more than 15 different elements have been obtained...

40. Tilted-foils setup for nuclear spin polarization of post accelerated beams

Hans Toshihide Tornqvist (CERN)

Submitted

Spin polarized nuclei are of great interest for many applications, for example in nuclear structure, solid state and biological physics. Recently, a project was started at ISOLDE to evaluate the tilted-foils technique applied to post accelerated beams at REX-ISOLDE. Thin tilted foils are introduced into the beam line which induces nuclear spin polarization and the degree of attained...
