DESCRIPTION:Speakers: ROTHE\, Sebastian (Johannes-Gutenberg-Universitaet  
 Mainz (DE))\nAt ISOLDE RILIS isotopes are resonantly ionized by high pulse
  repetition rate wavelength-tunable lasers. In recent years the performanc
 e of RILIS was substantially improved due to upgrade stages of the laser s
 etup. The dye laser installation has been completely renewed including the
  replacement of copper vapor pump lasers by solid state Nd:YAG lasers. As 
 part of the RILIS upgrade program\, a complementary fully solid state lase
 r system based on 10 kHz repetition rate Titanium Sapphire (Ti:Sa) lasers 
 has been built at CERN in collaboration with Mainz University. On account 
 of their advantages in terms of long-term stability and reliability\, Ti:S
 a lasers are used or planned to be used at the majority of on-line radioac
 tive ion beam facilities worldwide. In the beginning of 2011 the new Ti:Sa
  laser system was installed at ISOLDE RILIS alongside the dye laser system
 . Since then\, the Ti:Sa lasers have been used for a number of on-line exp
 eriments and their compatibility with the dye lasers and expected performa
 nce was demonstrated. With the implementation of Ti:Sa lasers the range of
  elements accessible with RILIS is extended. In particular\, an efficient 
 ionization scheme of astatine has been developed and the ionization potent
 ial of At atoms has been measured for the first time. The improved flexibi
 lity offered by the new dual laser system has greatly reduced the switchin
 g time from one element to another\, making it possible for more physics r
 uns to be scheduled.\n\nhttp://indico.cern.ch/contributionDisplay.py?contr
