Description

The dataset presented here is supplemental material for our paper published in Nuclear Instruments and Methods in Physics Research B 267 (2009) 3495-3499 (Lixia Tian, et al), entitled “Bremsstrahlung spectra produced by kilovolt electron impact on thick targets”. Experimental details have been given in this paper. The dataset includes our measured bremsstrahlung spectra on Al, Ti, Zr, Mo, and W thick targets for 5, 10, 15, 20, and 25 keV electron impact. Please notice that the experimental bremsstrahlung spectra in this dataset are multiplied by some factors (i.e., 3, 10, 30, 100 for 10, 15, 20, and 25 keV, respectively ) except for the case of 5 keV incident electron energy. The X-ray detector used in our experiment was an Ortec Si(Li) detector which was in vacuum, some detector parameters provided by the manufacturer were given in Tian et al's NIMB paper, and the detector active diameter was 4 mm. In our experiment, we made use of standard point sources to calibrate the detection efficiency of this X-ray detector (i.e., figure 1 in Tian et al's NIMB paper). Based on the figure 1 in Tian et al's NIMB paper, we can deduce the solid angle subtended by the detector, it was 0.003351, therefore we can estimate that the distance from the detector to the target was about 6.124 cm. These information may be useful for Monte Carlo simulations.
