Figure 3
Raw counts and experimental standard errors σ of three repeated measurements of the upstream and downstream ion chambers. Temperatures are given for the (a) 10 µm and (b) 50 µm foils. The 50 µm foil attenuated excessively towards the dark-current limit. Pre-edge counts read 1.3 × 105 and 3.5 × 104 for the 10 µm and 50 µm foils, respectively. (c) I0 is independent of temperature and remained relatively consistent with the exception of Bragg glitches. |
