  1. Last years of the SC-ISOLDE andmove to the PS-booster H. Haas CICECO, Universidade de Aveiro, 3810-193 Aveiro, Portugal and CERN/PH-IS, CH-1211 Geneve-23, Switzerland

  6. IsotopeSeparatorOnLine fürDeutscheExperimente Thanks to Jürgen Kluge

  7. Status in 1987 ISOLDE collaboration: DK, S, N, F, D, C ISOLDE has some 200 users An ever increasing number of non-nuclear applications, primarily from solid state physics Workhorse ISOLDE 2 in full swing ISOLDE 3 separator almost completed

  8. Status in 1987 ISOLDE collaboration: DK, S, N, F, D, CERN ISOLDE has some 200 users An ever increasing number of non-nuclear applications, primarily from solid state physics Workhorse ISOLDE 2 in full swing ISOLDE 3 separator almost completed

  9. Problems facing SC-ISOLDE Beamlines for ISOLDE 3 in Proton Hall to be constructed (and financed !) SC becoming very old ! SC operating personnel at retirement age (or gone) CERN management considers SC shutdown by 1989 ! Our unconventional solution Final management decision: SC shutdown December 1990

  10. ISOLDE 3 completion First separator test February 1987 Special beam observation equipment required Construction of beamlines Thanks to Erich Kugler and Klaas Gase First beam for experiments: February 1988 First operation with isobar separation: November 1990

  11. New facilities RILIS (Laser ion source) NICOLE (low temperature on-line nuclear orientation) UHV beamline (first surface experiments) HV platform (moderate post acceleration)

  12. SC operation 1975 to 1990 8 hr shifts for ISOLDE He-3 beam Thanks to Brian Allardyce, …

  13. SC-ISOLDE operation Shifts for ISOLDE Used by ISOLDE 2 Used by ISOLDE 2+3 Thanks to Helge Ravn, Rudi Stöckli, …

  14. Radiation safety problems(off the record) Nuclear criminology 1 Nuclear criminology 2 The fire brigade incident

  15. Shutdown of SCDecember 19, 1990

  16. The future of ISOLDE? ISOLDE collaboration 1990: + B, GB, I 315 Registered users 35+35 Running experiments Nuclear physics requests post-acceleration ! Of special interest: Astrophysics Challenge: Catch up with TRIUMF

  17. Post-acceleration alternatives Earlier: Tandem considered, but unpractical Working party formed 1988: B.W. Allardyce, H. Haas, P.G. Hansen, B. Jonson, C.Rolfs PRIMA project proposed June 1989: Conventional RFQ – stripper – IH system Further extensions considered

  18. The big decision Transfer of ISOLDE program ? Earlier: move to PSI considered Move to RAL discussed in 1988: Financial demands excessive! CERN management decides: Move to PS-booster ! Special thanks to Carlo Rubbia

  19. Transfer to PS-booster Project taken over by CERN Layout proposed by ISOLDE collaboration:

  20. The future has started ! Thanks to Daniel Simon, …
