keyword=Target position for Run 20629Target & raster patter for Run 20629 (a lead run), after moving the beam by 1mm in x. The raster pattern is after a cut in y_tar corresponding to the lead foil. Notice that the raster pattern is much more uniform than previously.
This run (a right arm run) was taken at 464.722 MeV/c at 120 degrees. This pattern will have to be monitored to make sure it stays uniform. It is not clear what caused the difference (such as hitting frame components, broken foil, etc.) except that it is different.
