ABSTRACT
The properties of keV x-ray radiations from Mo and Ti X-pinch plasma sources at the current of 800 kA were investigated by a pinhole transmission grating spectrometer. The spectrometer was characterized by a high linear dispersion rate (2.9 Å/mm), and from its time-integrated diffraction images, rich information about the X-pinch sources (e.g., source number, source size, and absolute spectra) could be obtained. Multiple hot spots were produced in all the Mo tests with loads made of two or four 25 μm wires with or without a shunt wire, and obvious increases both in the radiation intensity and in the source size around the spectral region of 2.6 keV were observed. In Ti X-pinch tests, a single keV x-ray burst with a source size of ∼200 μm and a time duration of ∼200 ps in full width at half maximum was obtained using a load made of two 50 μm wires plus a shunt wire. The intensity of x-rays decreased sharply from ∼1011 photon eV-1 sr-1 at 1 keV to ∼108 photon eV-1 sr-1 at 4 keV. The energy-dependent source size in the band of 1–4 keV is less than 100 μm and seemed to shrink quickly as x-ray energy increases.
