Hexaborides, such as lanthanum hexaboride (LaB6) and cerium hexaboride (CeB6), have low work functions, around 2.5 eV. They are also somewhat resistant to cathode poisoning. Cerium hexaboride cathodes have a lower evaporation rate at 1700 K than lanthanum hexaboride, but they become equal at temperatures above 185… pitchbook price per month

TīmeklisAbstract Standard Reference Materials (SRM) are stable materials which have one or more properties certified by the National Bureau of Standards. A general introduction is given to the types of SRM's and their certification. SRM's for X-ray diffraction are described in detail, including their intended use and their certified and other … Tīmeklisof the calibration standard, LaB6, is shown in Figure 2.12. In this image, each of the arcs is a crystalline peak. The x-y directions are the detector pixels, which are 2048 x 2048. The detector geometry is shown in Figure 2.13. The incoming beam interacts with the sample at a grazing incidence of roughly 3 to minimize Si diffraction.
