摘要：

Experimental investigation of an X-ray densitometer using K-line-emitting Cr and Al anodes with tube voltages of about 18 kV and tube currents of as much as 1 A are described which show an improved sensitivity and quantum flux. These results are in agreement with a theoretical model presented. In an SF 6 shock wave experiment densities down to 8*10-2 kg m-3 are measured with the Al anode and an accuracy of about 15% and a time resolution of 5 mu s. With the Cr anode the accuracy is better than 10% for densities of 4*10-1 to 5 kg m-3.
