In‐air beam size measurement results with fluorescent screen monitors and calculation results from an analytical Moliere program for (a) 430 MeV/n, (b) 302.1 MeV/n, and (c) 208.3 MeV/n. The red and blue points represent the measurements in the x and y directions respectively. The solid, dashed, and dotted lines show the calculation results for RS=0 mm, RS=12 mm (medium thickness), and RS=24 mm (maximum thickness).
