1. Alexander Herlert, CERN (PH-SME-IS)
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

2. New and active experiments at ISOLDE
INTC February 2010
5 new experiments: IS499 – IS503
132 approved RIB shifts (out of 183 requested)
8 experiments completed (3 REX experiments):
IS381, IS414, IS415, IS417, IS418, IS425, IS431, IS469
 69 active experiments for 2010 beam period

3. Injector schedule 2010 (V1.7) 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 …

4. 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%) 4

5. 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
HRS

6. 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

7. 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

8. 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
>2000h operation

9. 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
SiC target with Mg RILIS (GPS):
Despite some vacuum problems and contaminants good results for SSP
Successful run for COLLAPS experiment (n-def Mg isotopes)
ZrO 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 1st REX-ISOLDE run (GPS):
9C yield dropped quickly after start - not successful – need target test
ZrO target with RILIS for Ga (HRS):
Target broken right before on-line run - cancelled

10. 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 …

11. … 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.

12. … and last but not least Please welcome the next
ISOLDE Physics coordinator
Magdalena Kowalska
at the November INTC meeting!
