Time-integrated X-ray spectra from the plastic target were observed with a two-dimensionally curved crystal spectrograph. The bent quartz crystal,... 

Needless to say, the requirements imposed on the power supply and the electrical equipment are considerably more demanding for the successful operation of such a microprobe than of an ordinary x-ray spectrograph. The sample in the probe approaches being a point source the x-ray beam is therefore strongly divergent. Here a curved crystal... 

The apparatus as modified for x-ray emission spectrograph is also shown in Figure 11-1. The proportional counter may be used alone (pulse-height analysis Section 2.13) or a curved-crystal spectrometer can be employed to achieve better resolution. Analytical results were comparable to those quoted above, but localization of the area analyzed was considerably less sharp than the micron-diameter spot achieved in differential absorptiometry.
