Abstract
By adjusting the crystal for reflection of a wavelength corresponding to a voltage higher than the initial one applied on the storage capacitor, it has been found from oscillographical recording of the detector output signal as well as thedI▿ waveform from the discharge, that mostly X-radiation of high intensity and short duration was produced during intervals characterized by decreasing discharge current. The results obtained is in accordance withHändel's theory that a pincheffect acts in the flash X-ray discharge, and as a result of this, a voltage increase across the flash tube electrodes.
