D035600100012 A series of target-in and target-out D035600100013 measurements, was performed for each target. D035600100014 METHOD (SITA,EXTB) The experimental method is based on a D035600100015 modified transmission technique, where a proton beam D035600100016 is incident on a target and the outgoing particles are D035600100017 energy analyzed in order to separate transmitted and D035600100018 elastically scattered protons from reaction products. D035600100019 REL-REF (N,,CARLSON+,J,NIM,123,509,1975) Details of Apparatus D035600100020 And Experimental Technique. D035600100021 SAMPLE The targets, all significantly larger D035600100022 than the size of the beam, have thicknesses D035600100023 of the order of 100 mg/cm2 D035600100024 DETECTOR (TELES,SCIN,SCIN) plastic scintillators in a passing D035600100025 detector telescope, containing two passing detectors D035600100026 and two annular detectors. The passing detectors are D035600100027 used for the selection of protons with proper energy, D035600100028 while the annular detectors serve as active collimatorsD035600100029 ensuring that the identified protons are correctly D035600100030 directed on the target D035600100031 (TELES,CSICR,SCIN) Behind the target, the outgoing D035600100032 particles are energy analyzed in a CsI energy detector,D035600100033 thick enough to stop 200 MeV protons, in order to D035600100034 identify all unaffected or elastically scattered D035600100035 protons. In front of the energy detector is a small D035600100036 transmission detector that consists of an array of D035600100037 three overlapping plastic scintillators, one circular D035600100038 and two ring shaped. D035600100039 ERR-ANALYS (ERR-S) The errors shown are statistical. D035600100040 (ERR-SYS) The systematic errors due to uncertainties D035600100041 in the thickness and the uniformity of the targets D035600100042 vary from 1-4%.
