  1. Alexander Herlert, CERN (PH-SME-IS) ISOLDE scientific coordinator’s report INTC meeting, February 4, 2010 Running statistics 2009 Accelerator Schedule 2010

  2. ISOLDE schedule 2009 (Apr 20 - Nov 23) Requested shifts: • 662 in total • 96 different beams • 627 for 51 experiments Scheduled shifts (~70%): • 463 in total • 62 different beams • 437 for 39 experiments REX-ISOLDE: • 273 shifts requested • 140 shifts scheduled • 9 experiments (8 runs) • additional WITCH runs • (need REXTRAP) GPS HRS

  3. ISOLDE beam time summary 2009 • ISOLDE delivered 350 RIB shifts • 288 (82.3%) for INTC experiments • 62 (17.7%) other • Standard target check + TISD + REX-MD • Coordinators reserve: debugging, recovery, tests, LOIs • 40 research projects (IS experiments) – 6 with no beam • 2 LOIs • Integrated # protons • 6.65E+19 • Running for 223 days • More requests for GPS

  4. RIB overview GPS/HRS 2009 PSB septum leak (no target change) and PISOMOVE problem LINAC2 vacuum problem HRS frontend blocked Power cut and severe vacuum problems on/off-time from radiation monitors 52% of possible RIB shifts used (1.57 shifts/day) (55% in 2006 61% in 2007 56% in 2008) 223 days of on-line operation

  5. ISOLDE shift distribution 2009

  6. ISOLDE shift distribution 2000-2009

  7. Shift distribution 1998-2009 Number of shifts

  8. Key resources: targets 2009 • Actinide targets • 218 shifts (out of 350) [62%] • 12 new units + 2 old (one not used) • In total 27 targets • 23 new units • 2 not used

  9. Key resources: RILIS 2009 • 155.5 total RIB shifts • 152 shifts for INTC experiments • ~2000 hours for online work • includes setup, yield checks, etc. • >2100 hours total running time (incl. off-line tests) • 20 IS experiments (13 runs) • Beams: Mn, Be, Ga, Ag, • Nd, Po, Mg, Sn, • Zn, Ni • (all with Nd:YAG)

  10. REX-ISOLDE 2002-2009 • 91 RIB shifts delivered to experiments • + 5 RIB shifts for development

  11. New and closed experiments at ISOLDE Update November 2009 meeting 76 shifts out of 146 approved 4 new experiments IS495 - IS498 ISOLDE experiments to be closed IS410, IS420, IS438, IS461, and IS470

  12. Accelerator schedule 2010 (V1.3) ISOLDE dates: protons from PSB April 26 physics start ISOLDE April 29 protons stop November 22 (i.e. 29.5 weeks for physics as compared with 31 weeks in 2009) Longer shutdown period due to new HRS front-end and new vacuum system Several long periods of MD partly with parasitic beam to ISOLDE (not guaranteed)
