1. 66th ISOLDE Collaboration Committee meeting
Experiments and beam lines
66th ISOLDE Collaboration Committee meeting
CERN, 29 February, 2013
Marek Pfützner

2. Experiments Planned or discussed set-ups  Small, removable
b-NMR ()
SAND ()
CORSET ()
MAYA/ACTAR
Scattering chamber
 Large, fixed
MINIBALL (15)
HELIOS-like spectrometer
TSR
Spectrometer
For the begining two experimental stations are needed.
If HELIOS comes,
third will be necessary.
 - accepted proposal

4. Proposed stage 1 HEBT layout
Proposed and accepted at the previous ISCC meeting, October 30, 2012

5. Stage 1: two stations WALL Passage space 5.2m Electronics?
1.7m left for other setups
(1.3m, if passage counted from the open frame)
Electronics?
2.7m – open frame
Small removable
2.3m -rails
1m – common passage/dewars
1m – common passage/dewars
MINIBALL
Passage space

6. Helios magnet (no shielding)
WALL
Passage space
Stray field when 3T in the magnet
3Gs, more than cavities allow
5Gs, public (pacemaker) limit
10Gs, more than beamline allows
