- Abstract
We present spectral investigations of laser-plasma sources, in the extreme ultraviolet (EUV) and soft X-ray (SXR) regions from high-Z gases, dedicated for the X-ray coherence tomography experiments. The laser pulses of 4 ns and 650 mJ are used to produce plasma in a double gas puff target. The spectral investigation is done using 3 different spectrometers, spanning 1 nm to 70 nm of the EUV/SXR spectral region. Grazing incidence spectrometers are used in the ranges of 1–5 nm and 10–70 nm, and transmission grating spectrometer is used in the range of 4–16 nm. Specific wavelength bands were identified which are suitable for SXR and EUV XCT measurements. The compact size of the experimental setup of about ≈ 1:5 x 1:5 m² makes it suitable for laboratory environments.
