CERN-ISCC Meeting“Storage Ring Facility atHIE-ISOLDE”
3rd Nov 2011
Important steps:1) [email protected] Workshop at the Max-Planck-Institute for Nuclear Physics 28.-29.10.2010 (34 participants)2) Presentation of the [email protected] LOI at the CERN INTC- Meeting 02.02.2011 (about 60 coauthors)3) Presentation of the scientific (Yuri Litvinov) and technical Fredrik Wenander) part of the [email protected] Project at the STORI 2011 conference4) [email protected] Meeting at MPIK in order to discuss the open questions related to the preparation of the TDR for the INTC meeting (28.10.2011)5) TDR for the [email protected] project almost ready for submission, which is planned for the February 2012 INTC Meeting (> 120 coauthors, about 20 institutions)

Building costs: ~ 3MCHF
Proposed layout to fit the TSR at the west side:
- Installation above the CERN infrastructure-tunnel (not negotiable to move the tunnel: houses essential CERN signals and infrastructure)
- Tilted beamline coming up from the machine
Total surface TSR floor: 24.6x23.3m=573m2
of which 20x20m (400m2) reserved for the ring (final position of the ring within the building to be defined)
TSR floor approx . 3m above Hie Linac floor
Level of the center of beam at 1.77m above TSR floor
Total surface available basement: 12mx24.6m=295m2
to house power-supplies and additional racks (total 29m length floor space for the TSR equipment and 7m for the e-target equipment + 10 standard 19’’ racks and ECOOL HV cage 4x4m2)
Further information:Detailed estimation of the costs and manpowerrequirements are in preparation. preliminary values by MPIK exist; information from CERN neededFunding requests to the different agencies are under discussion (e.g. UK) Ideal time schedule: Building ready end of 2013,move of the ring in 2014, commissioning and start in 2015.Financial support by the ISOLDE Collaboration is needed in order to realize this project.

Negative magnetic moment of 7Be
Ionization of 7Be in the Sun can be ~ 20-30 %
[email protected] would be the best place to perform these experiments!

Measurements of (p,) or (α,) rates in the Gamow window of the p-process in inverse kinematics.
Similar experiments possible at [email protected]!
Ignore (p,n) component –
resulting in an upper limit
σPG ~ 4.0 mb
Non-smoker: 3.5 mb
Similar experiments with radioactive beams feasable at HIE-ISOLDE + TSR.
HIE-ISOLDE energy range fits perfectly!
