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

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

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

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

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 Stage 2: three stations variant A 5.2m 5m 1m 3.3m Electronics? Small removable 2.7m – open frame 2.3m -rails 0.8m Helios magnet (no shielding) Electronics? 1m – common passage/dewars 1m – common passage/dewars MINIBALL Passage space
