On-axis transmission efficiency response of a type I spectrometer constructed from stacked Al foils. This spectrometer can provide good measurements of energy between 4 and 15 keV. Curves show predicted transmission efficiencies observed by the first (filled squares), second (open squares), third (filled diamonds), fourth (open diamonds), fifth (filled circles), sixth (open circles) and seventh (crosses) detector in the stack. These correspond to the signal observed through 20, 40, 60, 80, 100, 120 and 140 µm of aluminium. Note: in contrast to the type II spectrometer, the I0 signal is collected in the absence of a foil.
