This review describes and categorizes the synthesis and properties of low density porous materials, which are commonly referred to as foams and are utilized for laser plasma experiments. By focusing a high-power laser on a small target composed of these materials, high energy and density states can be produced. In the past decade or so, various new target fabrication techniques have been developed by many laboratories that use high energy lasers and consequently, many publications and reviews followed these developments. However, the emphasis so far has been on targets that did not utilize low density porous materials. This review therefore, attempts to redress this balance and endeavors to review low density materials used in laser plasma experiments in recent years. The emphasis of this review will be on aspects of low density materials that are of relevance to high energy laser plasma experiments. Aspects of low density materials such as densities, elemental compositions, macroscopic structures, nanostructures, and characterization of these materials will be covered. Also, there will be a brief mention of how these aspects affect the results in laser plasma experiments and the constrictions that these requirements put on the fabrication of low density materials relevant to this field. This review is written from the chemists' point of view to aid physicists and the new comers to this field.

“…Elements such as beryllium and other light elements required for energy-efficient fusion burn can only be accurately studied using the presented X-ray phase-contrast approach. Such targets exhibit a hierarchy of scales and densities similar to the relative parameters explored in the present study [35].…”

X-ray 3D Imaging of Low-Density Laser-Target Materials

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.

“…The deuterated ratio of target materials is also important for an efficient fusion reaction [16]. For these purposes several targets have been developed, for example targets with a high deuterium concentration, metal foams and low-Z materials with transparency [17][18][19]. The type of tracer atom contained in the target depends on the purpose of the experiment.…”

Fabrication of high-concentration Cu-doped deuterated targets for fast ignition experiments

et al. 2022

In high energy density physics including inertial fusion energy using high power laser, doping tracer atoms and deuteration of target materials play an important role in diagnosis. For example, the low concentration copper dopant acts as an X-ray source for electron temperature detection while the deuterium dopant acts as a neutron source for fusion reaction detection. However, the simultaneous achievement of Cu doping, deuterated polymer, mechanical toughness and chemical robustness for the fabrication process is not so simple. In this study, we report the successful fabrication of a Cu-doped deuterated target. The obtained samples were characterized by inductively coupled plasma optical emission spectrometry (ICP-OES), differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). The simultaneous measurements of Cu K-shell X-ray emission and beam fusion neutron were demonstrated using a petawatt laser in Osaka university.
