Incident X-ray energy

MCP experiments were performed at AR-NE1 station of KEK (National Laboratory of High Energy Physics), Japan, using circularly polarized X-rays with the incident X- ray energy of 60 keV emitted from the elliptical multipole wiggler. Figures 1 and 2 show MCPs ofUSe and UTe, which have been measured at 150 and 80 K, respectively. 

Screen-Film Systems. According to Ludwig (5), crucial to the application of x-ray phosphors for intensifying screens is the efficiency with which the incident x-ray energy is converted to useful light energy as given by the expression ... 

Fig. 17. The ratios of the integrated intensities of the laimnelar reflections R(h/h ) = ([S(h)/S(h )], — [S(h)/S(h )]2)/[S(h)/S(h )l2 for a reconstituted cytochrome oxidase membrane multilayer. The subscript 1 denotes the incident X-ray energy and the index 2 corresponds to an energy far from the absorption edge, h = 4, h = 2, 3, 5 and 6 at incident X-ray energies near the iron K-absorption edge ( ). The f dispersion is most significant with h = 2 and h = 6. There is no dispersion at wavelenghts near the Co K-absorption edge (O)- After Stamatoff et al.

The plot of the mass absorption coefficients of matter against the incident X-ray energy or wavelength is called an X-ray absorption spectrum (XAS), where we find some jumps at particular X-ray energy, corresponding to K-, Li-, Ln-, Lnr etc. electron shell binding energies. 

Figure 4.11 MCA spectra from a single element of a Ge array detector showing the effects of including a Zr filter and Soller slit assembly. For the without filter data, the intensity of the incident beam was attenuated by approximately a factor of 20 by inserting an aluminum metal absorber into the upstream beam in order to maintain the detector at a non-saturating count-rate. The sample was an aqueous solution of human sulfite oxidase (0.2 mM Mo, 20 mM PIPES pH 7.0). The incident X-ray energy was 20900 eV, equivalent to the elastic scatter energy.

Fig. 21 The measured specular CTR scattering for an incident X-ray energy of 8.78 keV (lower panels) and the ratio between a similar data set measured at 8.94 keV (upper panels) at electrode potentials of 0.15 V (left) and 0.0 V (right). The solid lines are fits to the data to a single structural model and the ratio data set is calculated by fixed changes in the Cu atomic form factor.
