Piezoelectric Transformer Aided X-Ray Generation in Vacuum
- 12 Downloads
The results of an experimental study of x-ray generation aided by a ceramic piezoelectric transformer placed in vacuum are presented. X-rays were emitted with the piezoelectric transformer tuned to resonance at about 20 kHz. A characteristic emission peak of a titanium target at energy of 4.5 keV against the Bremsstrahlung background was observed in the measured x-ray spectra. The maximum energy of the x-ray Bremsstrahlung reaches 12 keV. This means that the electrons are accelerated in vacuum in the field of the piezoelectric transformer to at least 12 keV.
