- Sandwich radiator (runs 130-120):
- Dummy radiator, plexiglas 4mm, X/X0=1.2% (runs 131-136):
- No radiator (runs 143-138):
- Regular radiator 1: d1=20/d2=500/Nf=120, X/X0=0.6% (runs 144-149):
- Regular radiator 2: d1=20/d2=250/Nf=220, X/X0=1.4% (runs 155-150):
- Fibre radiator: 8 mats, X/X0=0.7% (runs 156-161):
- Rohacell radiator: HF71, X/X0=0.7% (runs 164,163):
Auxiliary measurements:
- No B-field: Si-strip and Pb-glass aligned on beam axis, DCs unchanged
(runs 166,165):
- Change setup: Si-strip and Pb-glass re-aligned for B-on;
DCs unchanged, He-pipe in, sandwich in front); Si1 GSI off beam (runs 167,168):
- He-pipe and Si1 OFF; DCs unchanged, B-on, sandwich in front of dipole,
sandwiche radiators in front of DC2-4 (runs 174-169):
