  1. Technical Advisory Board Ganil 2015 F. Chautard GANIL-Caen Sytze Brandenburg (KVI), Frédéric Chautard (chair, GANIL), Antoine Daël (SACLAY), Bernard Launé (IPNO), Olivier Laurent (GANIL), Jerry Nolen (ARGONNE), Eric Petit (SP2/GANIL), Josiane Sauret (GANIL), Thierry Stora (CERN), Mauritzio Vretenar (CERN) Will provide advice on the technical implications, including radio-protection and safety, of the future physics requirements and the possible large-scale maintenance needed.

  2. Two meetings and active participation of the members; Version 1 of the cluster reports taken into account; About 60 points of interest « extracted » The table has been sent to physicists to be complete and corrected Great creativity of the physicists; Not all synthesis tables were filled in by the cluster groups; Poor relevant informations from safety point of view; Beam descriptions uncompleted (A, I, W ranges); Already Version 2 of the reports; INTRODUCTION

  3. Method

  4. Main proposals SISSI LISE: • A mass spectrometer would be useful behind LISE3 or LISE2000 if not Sissi SPEG: • if SISSI is not replaced, use the CLIM target / LISE separator ensemble to produce and separate the fragmented beams and place SPEG behind LISE. • To have fragmented beams in SPEG, the most viable solution is to repair SISSI. INDRA …

  5. Main proposals Alpha optics evolution LISE: • New alpha separator SPEG: • A larger beamline rigidity of the SISSI-ALPHA • improve the ensemble SISSI-ALPHA in terms of acceptance

  6. Main proposals Ganil Test Source VAMOS: • Increase of the intensity of the heavy beams Pb, U up to 20 pnA SPEG: • Larger beam intensity CIRIL, ARIBE: • GTS type sources on the C0 platforms will be interesting, for a small part of the users, to have higher energies and current for heavy ions in the CSS1 energy range. SPIRAL1, SIRA • Replace the existing C01 ion source.

  7. Main proposals Selective ion sources SPEG: • To avoid problems related to radioactivity, it is essential that the beams be as isotopically pure as possible, in principle already before injection in the CIME cyclotron SPIRAL1, SIRA: • Improvement of beam purity

  8. Main proposals Ion source developments SPIRAL1, SIRA: • The development of Alkali beams 1+N+ compact ion source • New beams: 11Li, Al, Si, 26P, 27S, 44Ti, 56Ni, 68Se, 72Kr … • In my opinion the continuation of SPIRAL1 does not make much sense unless effort is devoted to the development of new beam species. LIRAT • More species should be authorized to be driven in the LIRAT line (Presently only 4 beams are authorized 6He, 19Ne, 32Ar and 35Ar). • …

  9. Main proposals New cave SPIRAL1, SIRA: • A requirement of another cave for the study of new beams will be very important (not SIRa) requirements • Using the intense 12C beam from GANIL, the fragmentation of various target materials would considerably extend the scope of SPIRAL1 and in some cases also boost intensities EXOGAM • Development : Use with post-accelerated beam from CIME (fission fragments and other beams-other targets) SPIRAL2 ?

  10. Conclusions Already Ongoing Projects: • SISSI2 • The development of Alkali beams 1+N • Study of high power target 3kW for other beams (36S , 40Ar, 20Ne) • fusion-evaporation: Pd foil in the SPIRAL 1 ECS and the usual thick 12C target as catcher of the direct beam. To be evaluated before starting a project: • Ion source developments • GTS integration in GANIL injector • Better time resolution without decrease of the beam intensity. • pulse suppressor • Deporting the chopper after the SME • New cave • New or improved alpha spectrometer • Re-injection in SSC • Direct line G1/G2 • …

  11. Conclusions • The TAB group found a great number of interesting ideas. May be yet too many to give clear answers. • the needs have to be stated more clearly, which should be done by a more intense collaboration between the clusters and the TAB. • Machine maintenance status around 2015 • To ease TAB work : • Fill the synthesis table in or complete the TAB table • For new beams fill in the proposed table below Ready for a more intense collaboration
