  1. TSR@ISOLDE Workshop, 10/2012“The TSR@ISOLDE Project” Klaus Blaum (MPI-Kernphysik, Heidelberg)and the TSR@ISOLDE Collaboration

  2. The idea

  3. A storage ring at an ISOL facility • Advantages • With respect to in-flightstorage rings • High intensity • Cooler beams • With respect to “direct” beams • Less background(target, beam dump) • Improved resolution • CW beam • Physics programme • AstrophysicsCapture, transfer reactions7Be half life • Atomic physicsEffects on half livesDi- electronic recombination • Nuclear physicsReaction studiesIsomeric statesHalo statesLaser spectroscopy • Neutrino physics

  4. The history: 2001/2002 D. Habs/P. Thirolf: A recycling ring for REX-ISOLDE and MAFF. D. Habs et al., Prog. Part. Nucl. Phys. 46 (2001) 343-358

  5. The history: 2004

  6. The history: 05/2010 Discussion between Klaus Blaum, Yorick Blumenfeld, Peter Butler, Piet van Duppen, and Christoph Scheidenberger about a storage ring (TSR) behind REX-ISOLDE.  Strong interest and excitement.

  7. The history: 10/2010 + strong support from F. Wenander

  8. Some technical details • Typical storage energy for 12C6+: E = 72 MeV 6 MeV/u • Vacuum: ~10-11 mbar • Acceptance of the TSR: 120 mm mrad well suited for REX-ISOLDE • Multiturn injection  mA of stored beam possible • Electron cooler  transverse cooling time of ~1s • RF acceleration and deceleration possible • Typical storage times: p @ 21 MeV: 60 h • 9Be1+ @ 7 MeV: 16 s12C6+ @ 73 MeV: 7470 s • 35Cl17+ @ 202 MeV: 318 s • 197Au51+ @ 710 MeV: 23 s Conclusion: The TSR is ideally suited as a storage ring at ISOLDE.

  9. The history: 02/2012 Submission of TDR to the INTC in Jan’12 02.02.2012: „The INTC strongly endorsed the TSR-TDR“

  10. The history: 04/2012 Eur. Phys. J. Special Topics 207, 1-117 (2012)

  11. The history: 05/2012 A major milestone 30.05.2012 Approval of TSR by CERN Research Board CERN's Research Board gave skeleton* approval for allocating resources to the TSR project (building and transfer line(s)).  The model for the Implementation is to move the ring to CERN in 2015, run it as an experiment for 3 years during which period CERN will investigate how to integrate it into its accelerator infrastructure, with the aim to run it as a facility from ~2018.  *The adjective "skeleton" means that the end date is fuzzy, and no definite resources appropriation is made yet. Thanks to Sergio Bertolucci, Paul Collier and Steve Myers for their strong support!

  12. Latest step: 08/2012 Mandate of the TSR Integration Study Working Group (Paul Collier)

  13. TSR@ISOLDE Collaboration: 129 scientists from 47 institutions in 19 countries

  14. Coupling to HIE-ISOLDE: Configuration Jura (west) side • Possible TSR installationabove the CERN service-tunnel • Tilted beamline coming upfrom the machine 25m 30m 10m (7m between floor and crane hook) Approx 3m higher than Isolde hall floor Cost study: Eliseo Perez-Duenas GS/SE  See talk by E. Siesling.

  15. Transfer line Coupling to HIE-ISOLDE: Transfer line  See talk by F. Wenander.

  16. In the ring: survival time, beam handling • Survival times • Coulomb scattering,electron capture and stripping • Residual gas, electrons in the cooler and gas target • Experiment reproduced by theory electron capture multiple scattering total 12C6+ (stripper foil) [charge breeder upgrade]  See talk by M. Grieser.

  17. Physics Programme • Conveners  See next talk by Peter Butler.

  18. Planning 2014 2015 2016

  19. Thanks It is amazing to see what a strong collaboration and an excellent team can reach within less than two years. I am sure TSR@ISOLDE (StorIS) will become a success story. Thanks for the support from all of you!
