A021400100011 METHOD (EXTB,BCINT,SITA) First, a low intensity run was made A021400100012 in which the individual beam particles were counted A021400100013 with plastic scintillators and C-11 activity was A021400100014 produced in a thick graphite block. Next, the C-11 A021400100015 activity in a 0.159 cm thick polystyrene target was A021400100016 determined relative to a digital readout ion chamber A021400100017 beam monitor in a high-intensity run. Finally, the A021400100018 C-11 activity in a thick graphite block was also A021400100019 determined at high beam intensity relative to the ion A021400100020 chamber. A021400100021 ANALYSIS The C-12(C-12,x)C-11 cross section was A021400100022 calculated using data from the three runs. A021400100023 ADD-RES (COMP) A021400100024 SAMPLE Thick graphite block and 0.159 cm thick polystyrene A021400100025 target. A021400100026 ERR-ANALYS (ERR-1,,1.5) Uncertainty due to shifting of beam A021400100027 position, variations in placement and angle of the A021400100028 targets, and losses in counting 12C ions due to A021400100029 pileup or coincidence problems.
