D401900100017 SAMPLE electroplated highly enriched (99.51%) Tellurium-124 D401900100018 on 20 microns of Ti backing foils. The 5-10 mg/cm**2 D401900100019 tellurium-124 layer was covered by 10 micron Al foil. D401900100020 five stacks each consist of four or five samples and D401900100021 Cu monitor foils were irradiated for 0.75 To 3.0 Hour D401900100022 with 50 namp beam current. The degradation of the D401900100023 proton energy in the stacks was calculated according D401900100024 to C.F. Williamson et Al.,The decay data for the D401900100025 isotopes considered were taken from e. Browne and r.B. D401900100026 firestone, table of radioactive isotopes (ed. Shirley D401900100027 V.S.) Wiley, New York 1986, and U. Schotzig and H. D401900100028 schrader, ptb report, ra-16/4. The beam current was D401900100029 measured by using a Faraday cup. The beam current and D401900100030 the energy degradation along the stack were controlled D401900100031 by monitor reactions on Cu and Ti.
