keyword=Reactz for Mutli-12C foilsFigure 1 shows the reactz spectrum for the multi-12C foils for Run # 3914. The Right HRS momentum was 2.704 GeV/c, Setum current was 352A. This run was after JP installed new foils yesterday afternoon. From Figure 1, only two of the foils are seen. After talking to Alexandre Deur, he said that the collimators cut out the -10 cm upstream foil. The +20 cm downstream and -20 cm upstream foils are not seen very well at 9 degrees. So it is not surprising that we do not see them now.
Figure 2 shows the ytg spectrum for this run. The central peak is centered at zero.
Results from physics replay:
y_tg center from max is at 0.250002 +/- 0.5 mm.
y_tg center from fit is at 0.0277122 mm.
