A1 - Hodoroaba, Vasile-Dan T1 - Accurate determination of small spot X-ray tube spectra by means of direct measurement in a calibrated instrumental setup N2 - A calibrated instrumental setup was specially developed for the purposes of accurate measurements of absolute X-ray spectra emitted by modern micro-focus, low-power X-ray tubes. By knowing all the instrumental parameters the spectra measured with the 16 m long setup are recalculated into emitted X-ray tube spectra in photons per eV per msr per nA per s.
