All targets had a O242400100018 natural abundance of the corresponding isotopes. O242400100019 DETECTOR (HPGE) HPGe detector with active muon-veto, multi- O242400100020 layer inner shielding, and outer shielding with 10 m O242400100021 of water equivalent artificial overburden O242400100022 METHOD (EXTB,SITA,TTM,ACTIV,GSPEC) The initial beam energy O242400100023 was 228 MeV, which then was reduced to 100 MeV or 180 O242400100024 MeV with a wheel-mounted wedge. The experiment was O242400100025 done in a pencil-beam scanning treatment room. The O242400100026 exit nozzle of the beam treatment head was covered by O242400100027 a kevlar foil with thickness of 0.24 mm. The beam O242400100028 current was measured by Faraday cups. O242400100029 ERR-ANALYS (ERR-S) reported statistical uncertainty O242400100030 (ERR-SYS) reported systematic uncertainty O242400100031 The following contributions to the uncertainty budget O242400100032 were considered: target mass, impurities, detector O242400100033 efficiency, half-lives, time measurement, dead-time, O242400100034 Faraday cup efficiency, and beam characteristics. The O242400100035 two major source of uncertainty were: O242400100036 (ERR-1) detector efficiency (1.732 %) O242400100037 (ERR-2) long-/short-term variation of beam fluence O242400100038 (0.9%) O242400100039 See Table 3 for more detailed information.
