Figure 3
Transmission of synchrotron radiation through 200 nm of Al or Si3N4 calculated using the CXRO database (Henke et al., 1993). The Al window has a good transmission up to the Al 2p edge at around 72 eV and begins to increase again after 200 eV. The Si3N4 window has much smaller transmission due to the Si 2p and N 1s edges at about 100 and 400 eV. Both windows have relatively good transmission above 500 eV. |
