Table 2
Absorption cross section, density, and filter thickness of the Mg, Al, and Be filter at Kα line energies of Mg, Al, and Si.
| Absorption cross section μ (cm2 g−1) | ρ (g cm−3) | d (μm) | |||
|---|---|---|---|---|---|
| Element | 1.254 keV (Mg) | 1.487 keV (Al) | 1.740 keV (Si) | ||
| Be | 307.76 | 184.47 | 114.47 | 1.84 | 25.4 |
| Mg | 502.39 | 4084.09 | 2782.42 | 1.74 | 5.1 |
| Al | 648.13 | 411.68 | 3111.63 | 2.70 | 6.4 |
Notes. The filter thickness is adopted from Yin et al. (1993). Absorption cross sections were determined using the web tool xraylib (Schoonjans et al. 2011).
