Achieving optimal design and precise control of the internal structure of laser-target materials are the primary objectives in various laser physics experiments, particularly in generating high flux photon and neutron beams. The study of low-density materials poses considerable challenges for X-ray analysis due to their high transparency and minimal contrast. In this study, to obtain clear visualization of foams with sparse structures, we used phase-contrast X-ray tomography, utilizing a high-quality monochromatic X-ray beam from the synchrotron radiation source PETRA-III at DESY. Employing phase-contrast algorithms, the 3D structure of a foam-suspended glass microsphere inside the plastic cylinder was reconstructed with a level of image quality sufficient to visualize uniformity, displacement, and surface roughness on both sides of the microsphere. The primary focus of this investigation was a CH plastic capillary including 10 mg/cc CHO foam with a glass microsphere positioned at the center. The results of this study demonstrate that phase-contrast X-ray tomography with coherent synchrotron radiation is an effective and valuable technique for the development of new laser targets containing structured low-density materials.

“…Historically, the dense plasma device was developed as a fusion device with most of its studies being done in hydrogen and its isotopes in relation to the neutron emission with the aim of determining neutron production mechanisms. During its early stages of development, the DPF has been used as a neutron source for pulse activation analysis [3], as a spectroscopic source for production of highly ionized species [4] and as a pump source for lasers [5]. The DPF device, however, not only is a source of neutrons but also emits highly energetic ions, relativistic electrons and abundant amount of X-rays [6][7][8].…”

A new low energy (1.5 kJ) Mather-type dense plasma focus, called Sahand University of Technology Dense Plasma Focus (SUT-DPF) device has been designed, constructed and operated. The paper reports on the preliminary results with argon as filling gas. A Rogowski coil has been used to measure the experimental discharge current. The current signal contains a set of data from physical processes in the device as well as discharge current characteristics. The device circuit parameters were calculated using the short-circuit test. In a typical discharge experiment, these values were obtained: the discharge period was 15.4 ± 0.1 ls, the discharge current 100.8 ± 0.7 kA, the total inductance of the device 197 ± 3 nH and electrical resistance of circuit 11.3 ± 1 mX. The Rogowski coil sensitivity was obtained 49.65 ± 0.3 kA/V. A resistive voltage divider was also used to measure the transient voltage across the plasma. The experimental results showed that the pinch time at a constant pressure of the argon gas, decreased by increasing the charging voltage. The optimum pressure for 5, 6.5 and 7.5 kV obtained 0.75, 1 and 1.5 mbar, respectively.

In our preliminary experiments, reported in this paper, dense plasma focus (DPF) device is used for deposition of thin (a few nanometers of thickness) chromium layers. Such films have been deposited on silicon wafers by ablation of the chromium target using highly dense and highly temperature argon-oxygen plasma. Two films with different structure were obtained at the same substrate temperature using a fixed shot number (equal to 7). Surface topology and depth profiles of the films were studied by means of scanning electron microscopy (SEM) and secondary-ion mass spectrometry (SIMS), respectively.
