O174600100017 MONITOR ((MONIT)13-AL-27(D,P+A)11-NA-24,,SIG) O174600100018 The currents obtained in these two methods were O174600100019 reproduced using a cross-section AL-27(D,P+A)11-NA-24 O174600100020 of 24.6 mb O174600100021 REL-REF (R,O1514001,G.Lhersonneau,J,NIM/A,576,371,2007) O174600100022 Details of the target chamber O174600100023 SAMPLE The target has both length and diameter of 15 mm. O174600100024 The aluminium wall and entrance window of the containerO174600100025 are 0.5 mm thick. The targets were either a graphite O174600100026 powder of density 1.76, heavy water or light water. O174600100027 DETECTOR (GE).A coaxial Ge-detector . O174600100028 CORRECTION Errors on the conversion factor are thus quasi-fully O174600100029 defined by the cross-sections, without bias from O174600100030 experimental conditions.This defines neutron yields to O174600100031 about 15% accuracy.The agreement between both methods O174600100032 was very good(TOF and ACTIV).After these tests, it O174600100033 turned out that the scale of the original measurements O174600100034 had to be multiplied with factors of 1.07(4) for the O174600100035 carbon, 0.87(6)for the heavy water and 0.94(9) for theO174600100036 light-water targets. These factors give an estimate of O174600100037 the systematical errors on relative yield measurements,O174600100038 i.e. 8% for heavy water to carbon and 11% for light O174600100039 water to carbon. O174600100040 COMMENT *By author*.All targets have been irradiated with closeO174600100041 to 1 nA positive deuterium ions during 14 hr,during, O174600100042 which the foils have been exposed to the neutron flux O174600100043 generated by the targets. O174600100044 *By author*. The carbon target was irradiated first in O174600100045 order to validate the method by comparison with time-ofO174600100046 flight data. Irradiations of heavy-and light-water O174600100047 targets were performed several months later.
