Measurement of beam properties and reproducibility on recent PBFA II target shots
Recent proton experiments on PBFA II used a 2 micron gold foil cone to characterize the ion beam. Using the ion beam images obtained by viewing such foils with time-integrated x-ray pinhole cameras, the beam centroid axial location and azimuthal symmetry have been analyzed for a recent series of target shots. Azimuthal symmetry on the target midplane on individual shots varies from 14%--35%. Averaged over the entire series of shots, inferred intensities on the target midplane vary by 21% to 41% from quadrant to quadrant. The beam profiles and beam reproducibility are vital to the interpretation of the results of these target experiments. A possible correlation between the ion beam full-width-at-half-maximum and the integrated counts from a nuclear activation diagnostic was observed.
