ISOLDE scientific coordinator’s report INTC meeting, June 23, 2010 Alexander Herlert, CERN (PH-SME-IS) Beam requests 2010 ISOLDE Schedule 2010 Start of running period 2010

New and active experiments at ISOLDE INTC February 2010 • 5 new experiments: IS 499 – IS 503 • 132 approved RIB shifts (out of 183 requested) • 8 experiments completed (3 REX experiments): IS 381, IS 414, IS 415, IS 417, IS 418, IS 425, IS 431, IS 469 69 active experiments for 2010 beam period A. Herlert INTC June 23, 2010

Injector schedule 2010 (V 1. 7) ISOLDE dates: protons from PSB May 3 physics start ISOLDE May 6 protons stop November 22 (i. e. ~29 weeks for physics as compared to 31 weeks in 2009) Several long periods of MD partly with parasitic beam to ISOLDE (not guaranteed) Technical stops keep changing dates … A. Herlert INTC June 23, 2010

ISOLDE beam requests 2010 • Beam requests: • 627. 5 RIB shifts requested by 50 experiments (17 with no request) • For comparison to 551 RIB shifts requested in 2008 and 627 in 2009 • Requested RILIS shifts: 350 >50% (337 in 2008 and 359 in 2009) • Requested REX-ISOLDE RIB shifts: 333 (273 in 2009) • Additional ~40 shifts for TISD, LOIs + off-line MD … • Scheduled runs (present status): • 469 RIB shifts in total (609 shifts for running period incl. PSB setup) • 432 RIB shifts for 41 experiments • 74 different beams • 19 beams and 36 experiments not scheduled (17 of those with no request and/or completed) • 7 REX-ISOLDE runs for 11 experiments with ~160 RIB shifts (~37%) A. Herlert INTC June 23, 2010

ISOLDE schedule 2010 - overview ISOLDE program 2010 (Version 1. 2): physics started May 6 protons stop Nov. 22 ~29 weeks for physics So far scheduled: • • • 41 IS experiments 3 TISD runs 6 LOIs >460 RIB shifts >70 different beams GPS A. Herlert HRS INTC June 23, 2010

ISOLDE schedule 2010 – REX-ISOLDE • 25 active REX experiments • 17 requested beam • 11 scheduled • 3+3 share target/setup (but different beams) • 7 runs • 3 days for setup • + LOI (TF polarization) • + 2 WITCH on-line runs • Need REX-TRAP • Operation of WITCH still not compatible with EBIS/ LINAC operation A. Herlert INTC June 23, 2010

ISOLDE schedule 2010 – Targets • 28 target units planned • 12 for HRS • 16 for GPS • Some old or to be reused during period • 10 new UCx units (1 HD) • TISD • 3 dedicated runs: - Molten metal target plus VADIS - low work-function cavity + Sm RILIS - High density UCx A. Herlert INTC June 23, 2010

ISOLDE schedule 2010 – RILIS • 14 RILIS runs planned • • No off-line run 1 target test (Sm) dense schedule At scheme to be tested • >210 RIB shifts planned • >2000 h operation A. Herlert INTC June 23, 2010

First on-line runs in 2010 • TISD: Sm RILIS target test (with low work-function cavity) at GPS: • No Sm beam observed – not successful • SSP collections with YO HP target (GPS): • Strong stable contamination present • Not much physics output • Good tests with promising yields of Fe and Cr beams • Si. C target with Mg RILIS (GPS): • Despite some vacuum problems and contaminants good results for SSP • Successful run for COLLAPS experiment (n-def Mg isotopes) • Zr. O target with RILIS for Cu (HRS): • Successful run for COLLAPS experiment (n-def Cu isotopes) • Good results for SSP despite RFQ problems • YO CP target for 1 st REX-ISOLDE run (GPS): • 9 C yield dropped quickly after start - not successful – need target test • Zr. O target with RILIS for Ga (HRS): • Target broken right before on-line run - cancelled A. Herlert INTC June 23, 2010

New procedure for proposals Safety file for all experiments required • all new INTC proposals need to provide a ‘safety file’ with the submission of the proposal (or addendum) • Safety aspects will be discussed with CERN specialists before the INTC meeting • Approval from Research Board only with endorsed safety file More details soon … A. Herlert INTC June 23, 2010

… finally This is my last INTC meeting as ISOLDE Physics Coordinator… …Thanks a lot to all colleagues in the local ISOLDE Physics group, in the ISOLDE ‘technical’ groups, and in the INTC, and of course thanks a lot to all the ISOLDE Users for their cooperation and support in the last years. A. Herlert INTC June 23, 2010

… and last but not least Please welcome the next ISOLDE Physics coordinator Magdalena Kowalska at the November INTC meeting! A. Herlert INTC June 23, 2010
