126Sn Run Aug. 2011

Modified KHS1; added about 0.4 mg/cm2 Grafo colloid
Target: (KHS1m) 1.0 C | 5.01 Gd | 1.1 Ta | 5.02 Cu | 5.6 Cu mg/cm2
ORNL set up: 4 Clover detectors at 3 cm + chamber radius from target.
Particles detected in triple solar cell: size 15x15 mm each.
30 mm behind target, central detector covers an opening of ±14° outer detectors wired together, each covers 17 - 44°
Beam: 126Sr 378 MeV(Coulomb barrier = 461 MEV).
