Discussion between Klaus Blaum, Yorick Blumenfeld, Peter Butler, Piet van Duppen, and Christoph Scheidenberger about a storagering (TSR) behind REX-ISOLDE. Strong interest and excitement.
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 h9Be1+ @ 7 MeV: 16 s12C6+ @ 73 MeV: 7470 s35Cl17+ @ 202 MeV: 318 s 197Au51+ @ 710 MeV: 23 s
Conclusion:The TSR is ideally suitedas a storage ring at ISOLDE.

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.
A major milestone
Thanks to Sergio Bertolucci, Paul Collier and Steve Myers for their strong support!

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!
