O136500100016 FACILITY (CYCLO,4ZZZDUB) The U-400M cyclotron. O136500100017 INC-SOURCE The helium isotopes were produced using the primary ionO136500100018 beams of Li-7(35.5MeV/A) on carbon. O136500100019 The striping of proton from the Li-7 on the 1.1-mm O136500100020 carbon target was used. The intensity of He-6 was O136500100021 6000- particles per second. O136500100022 SAMPLE The special 'sandwich-type' piles of targets of Bi-209,O136500100023 820-mug/cm**2 thickness, 55-mum thick Mylar films for O136500100024 registration of fission fragments and additional O136500100025 absorbers made of Al(60-200-mum) were manufactured. O136500100026 The aluminum-foils and bismuth targets were tested on O136500100027 uranium contamination using neutron activation method. O136500100028 DETECTOR (SILI) For monitoring the secondary beam. Si(Li) with O136500100029 dimensions 32. mm in diam. x 4.15 mm2 was about O136500100030 6000 pps for 2.1011 pps of 7Li ions O136500100031 Additionally, an dE detector 4150 mu-m in thickness O136500100032 reduced the energy down to 70 MeV+-8% (FWHM) at the O136500100033 experimental target position. O136500100034 (TRD) 55 mu-m-thick Mylar films for registration of O136500100035 fission fragments and additional absorbers made of O136500100036 Al (60+220 mu-m) were manufactured O136500100037 ERR-ANALYS (ERR-T) The total uncertainty of the measured fission O136500100038 cross section. The uncertainty includes: O136500100039 (ERR-1) High limit of counting error. O136500100040 (ERR-2) The losses of ions connected with the O136500100041 absorption inside the targets and aluminum foils and O136500100042 with multi-scattering.
