C236100100010 INC-SPECT The proton energy was always 300 GeV except for a C236100100011 period representing ~5% of the flux of the second C236100100012 irradiation, in which it was 400 GeV. On the basis of C236100100013 what follows, we do not believe this significantly C236100100014 effects our results. C236100100015 SAMPLE The targets consisted of eight layers of graphite C236100100016 (48x40x1 mm), wrapped in A1 foil. Before irradiation C236100100017 the graphite was heated to ~2500 C for 30 seconds C236100100018 under an argon atmosphere to ensure that the Li and C236100100019 Be content were less than 10**-13 g/g. C236100100020 METHOD (ACTIV,MASSP) Irradiations were carried out C236100100021 parasitically in the neutrino beam line of the FNAL C236100100022 accelerator several inches in front of the main C236100100023 production target. Two irradiations were performed, C236100100024 lasting 45 and 60 days, and receiving total C236100100025 integrated fluxes of ~3x10**17 and ~1x10**18 protons C236100100026 respectively. Several weeks after irradiation the C236100100027 targets were returned to our laboratory for analysis. C236100100028 Cross sections for the production of Li and Be C236100100029 isotopes in carbon targets irradiated by 300 GeV C236100100030 protons have been measured by mass spectrometry.
