44. IMPRUVMENT in RILIS SELECTIVITY and SPECTRAL RESOLUTION by the use of TIME-OF-FLIGHT TECHNIQUE

Viacheslav Mishin (Institut for Spectroscopy RAS)

Although the selectivity of resonance ionization laser ion sources is high, nevertheless, it does not sufficiently large to carrying out many crucial experiments with radioactive isotopes particularly in studies of isotopes located very far from the valley of element stability. This report discusses the improved selectivity of the RILIS made possible by in-source time-of-flight ion...

53. ISOLDE RILIS: upgrade and development report.

Valentin Fedosseev (CERN)

18/11/2009, 16:50

At ISOLDE RILIS the resonance ionization of isotopes is provided by high pulse rate dye lasers. Until 2008 the dye lasers were pumped by copper vapor lasers built a long time ago in Russia. Following a plan for upgrade of the laser setup, two new 100W Nd:YAG lasers have been installed at RILIS. Operation of RILIS with the new pump lasers resulted in a noticeable improvement in the production...

16. Latest news from REX: the 2009 campaign, new beams and technical developments

Didier Voulot (CERN)

18/11/2009, 17:10

During 2009, REX has accelerated new particle types, and promising results have been obtained for the charge breeding of very heavy neutron-rich ion beams. These will be reported, as well as experience from the 2009 measurement campaign; results from the first tests with diamond detectors used as beam diagnostics; and the development work on a tilted foil set-up for the production of polarized...

25. The New ISOLDE Frontends

Stefano Marzari (CERN)

18/11/2009, 17:30

A new design of Frontend has been developed at ISOLDE in view of replacing the existing and aging Frontends. Whilst maintaining compatibility with the present target design, new improvements and modifications have been incorporated into Frontend #6 and #7. These include simplified mechanics, a ceramic high voltage insulator, metallic joints, re-design of the beam optics, a rigid chassis and an...

39. Frontend #6 test results

Tim Giles (CERN)

18/11/2009, 17:45

In this talk I will present the features and optics of the new generation of Isolde frontends. A test stand for frontend #6 has been built and beam has been extracted from a target equipped with a standard Isolde ion source. I will show calculated tunes adapted for the GPS and HRS separators, and compare them with emittance measurements made on the test stand.

14. Isotopic fingerprints of gold-containing luminescence centers in 28Si

Karl Johnston (Universitaet des Saarlandes)

18/11/2009, 18:00

A consequence of a project to grow enriched material for a re-definition of the kilogram, optical spectroscopy on the resulting crystals has revealed many unexpected properties of supposedly well-known (and certainly well-studied) optical centres in Silicon. It has been shown that a dramatic reduction in linewidth of many deep luminescence centers in highly enriched 28Si can lead to the...
