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

(100 Gauss)

• Stray field from unshielded HELIOS solenoid
  (shown at XT02)
• 10 100 Gauss at beamline (max 8)
• 10 20 Gauss at Linac (max 2)
• Local magnet shielding design being evaluated
