IPF was used to irradiate samples C225100100015 at energies bellow 100 MeV C225100100016 (LINAC,1USABNL) The Brookhaven Linac Isotope Producer C225100100017 BLIP consists of a beam line and target area for C225100100018 isotope production that uses protons up to 200 MeV C225100100019 energy and 110 mu-A intensity from the BNL Linac. C225100100020 DETECTOR (HPGE) Canberra Model GC2020 High-Purity Germanium C225100100021 detector with a relative efficiency of 20% was used C225100100022 for radioactivity measurements C225100100023 METHOD (ACTIV,CHSEP). Activation method was used followed by C225100100024 chemical separation. Samples were irradiated for C225100100025 period from 3 to 220 hours by average current ranging C225100100026 from 30 mu-A (BLIP) to 200 mu-A (IPF) C225100100027 SAMPLE For irradiations at IPF metallic Th was arc melted and C225100100028 rolled to thickness 637.6 mg/cm2. The purity was betterC225100100029 than 99.6%. The discs were electron-beam welded into C225100100030 machined Inconel capsules. Three different target were C225100100031 used at IPF. C225100100032 For the irradiations at BLIP, Th foils (0.125 mm, C225100100033 99.5% purity) were purchased from Goodfellow C225100100034 Corporation. For a typical irradiation, a 27.9 mm C225100100035 circle was cut from the foil and wrapped in 0.025 mm C225100100036 Al metal foil C225100100037 ERR-ANALYS (ERR-1,6.7,11.9) Systematic uncertainty in target mass C225100100038 (ERR-2,7.,10.)
