A022800100027 METHOD (SITA) Differentially pumped gas-target system. A022800100028 (BCINT) Calorimeter, 4 watts power, with an active areaA022800100029 of 3.5 cm diameter. A022800100030 DETECTOR (SIBAR) The detector setup consisted of eight, 1 mm A022800100031 thick silicon detectors of 5*5 cm**2 area placed aroundA022800100032 the beam axis: they formed a 14 cm long parallelepipedA022800100033 in the target chamber. Each detector was shielded by aA022800100034 25 mu-meters thick nickel foil in order to stop the A022800100035 He-4 ejectiles, the elastic scattering products, and A022800100036 the light induced by the beam. A022800100037 (SCIN) A NE102A plastic scintillator, 1*1 m**2, 3.5 cm A022800100038 thickness, was placed below the target chamber and usedA022800100039 to veto cosmic-ray-induced events in the detectors. A022800100040 Dead time effects in the detectors were monitored usingA022800100041 a pulser and were kept below 3%. The detector A022800100042 efficiency in the setup was calculated with a A022800100043 MONTE-CARLO simulation.
