Turning Noise Into Data: Characterization of the Van Allen Radiation Belt Using SDO Spikes Data

“…The total thicknesses of the Zr and Al filters at the entrance and detector are 4,000 and 3,000 Å, respectively (Lemen et al, 2011). According to the NIST ESTAR tables (Berger et al, 1984) It can be observed throughout the paper that the NSPIKES correlation tests are more sensitive to low electron energies. As it can be seen in Tables 2 and 3, MAGED low energy electrons (ex.…”

“…The total thicknesses of the Zr and Al filters at the entrance and detector are 4,000 and 3,000 Å, respectively (Lemen et al., 2011). According to the NIST ESTAR tables (Berger et al., 1984), the average path length traveled by 40 keV electrons in Al before they stop is 3.90 × 10 −3 g cm −2 or 48 times the thickness of the two Al filters, while the average path length traveled by 40 keV electrons in Zr is 5.19 × 10 −3 g cm −2 or 20 times the thickness of the two Zr filters. The Zr filters thus stop more 40 keV electrons than the Al filters.…”
