“…65 To guide the development of next-generation highpower targets for particle physics research, Bidhar et al prepared ZrO 2 NFs by electrospinning and used them as a nanoreactor to evaluate its resistance to radiation damage using a medium-voltage electron microscope tandem (IVEM-Tandem) facility. 66 The IVEM-Tandem consists of an in situ TEM platform and ion beamline that enable operando observations of defect formation and evolution during irradiation. They irradiated some isolated ZrO 2 NFs with a grain size of about 10-15 nm by applying low-energy heavy ionizing radiation, and the ion irradiation caused negligible dislocation in the NFs (Figure 2D,E).…”

Electrospun nanofibers (NFs) have shown excellent properties including high porosity, abundant active sites, controllable diameter, uniform and designable structure, high mechanical strength, and superior resistance to external destruction, which are ideal nanoreactors for in situ characterizations. Among various techniques, in situ transmission electron microscopy (TEM) has enabled operando observation at the atomic level due to its high temporal and spatial resolution combined with excellent sensitivity, which is of great importance for rational materials design and performance improvement. In this review, the basic knowledge of in situ TEM techniques and the advantages of electrospun nanoreactors for in situ TEM characterization are first introduced. The recent development in electrospun nanoreactors for studying the physical properties, structural evolution, phase transition, and formation mechanisms of materials using in situ TEM is then summarized. The electrochemical behaviors of carbon nanofibers (CNFs), metal/metal oxide NFs, and solid‐electrolyte interphase for different rechargeable batteries are highlighted. Finally, challenges faced by electrospun nanoreactors for in situ TEM characterization are discussed and potential solutions are proposed to advance this field.image

“…The nanopolycrystalline structure of nanofibers also helps to resist radiation damage effects as the associated large number of grain boundaries acts as defect sinks to limit lattice defect growth and mobility. Results from in-beam tests at CERN's HiRadMat facility and in-situ ion irradiation Transmission Electron Microscopy (TEM) at the Argonne National Laboratory -Intermediate Voltage Electron Microscopy (IVEM) facility show promising evidence of thermal shock and radiation damage tolerance of nanofiber mats [22]. High-Entropy Alloys (HEAs) are also being explored as potential beam-intercepting materials in collaboration with the University of Wisconsin-Madison.…”

High power target systems are crucial elements in enabling future neutrino and other rare particle beams. These systems transform intense source of protons into secondary particles of interest to enable new scientific discoveries. As primary beam intensities increase in next-generation multimegawatt accelerator facilities, high power target systems face key challenges. Thermal shock and radiation damage effects in beam-intercepting devices were identified as the leading cross-cutting challenges of high-power target facilities. Target materials R&D to address these challenges are therefore essential to enable and ensure reliable operation of future accelerator target facilities. This paper provides an overview of the R&D activities underway to help support high power target systems development for next-generation multi-MW facilities.

“…[24][25] However only a few researchers made some attempts on fabrication of potential radiation shields via electrospinning technique. [26][27][28][29][30] The type of filler used in polymer matrix has crucial effect on radiation shielding efficiency of electrospun surfaces. It was reported that Bi 2 O 3 doped mats had higher Xray attenuation ability than WO 3 doped samples in same polymer matrix and WO 3 concentration should be higher for reaching similar radiation shielding efficiency.…”

To develop an alternative surface to lead‐based shieldings, we synthesized bismuth(III) oxide‐free and bismuth(III) oxide‐loaded poly(vinyl) chloride solutions via electrospinning process. Nanocomposite surfaces were characterized by scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis and fourier transform infrared spectroscopy. Thickness and electrical conductivity of different samples were measured and linear attenuation coefficients, half‐value length, tenth‐value length, mean‐free path and shielding performance were calculated with corresponding formula. The attenuation behaviors of samples were plotted by X‐COM software. According to results of instrumental analysis, micro‐particulated bismuth(III) oxide powder was adapted into nanofibrous structures and bismuth(III) oxide loading lead to development on thermal behaviors. Besides, bismuth(III) oxide‐loaded poly(vinyl) chloride samples showed limited electrical conductivity and improved X‐ray radiation attenuation. Increasing weight percentage of bismuth(III) oxide caused a decrease on half‐value length, tenth‐value length and mean‐free path values. It was concluded that studied samples should be used as multi‐layer form for achieving desired radiation dose reduction. By increasing w% of bismuth(III) oxide powder, more effective surfaces for radiation shielding can be manufactured.
