The X-ray source based on parametric X-ray radiation (PXR) has been developed and employed for users studies at the Laboratory for Electron Beam Research and Application (LEBRA), Nihon University. The X-ray energy of the LEBRA-PXR source is limited to 34keV in the case of using Si(220) as a radiator. Samples containing elements heavier than cesium such as lanthanoid are difficult to treat for...

Compact, efficient, and high-quality plasma wakefield-accelerated free electron lasers (FELs), betatron sources, and novel synchrotron radiation (SR) coherent sources are under development to meet the latest experimental and technological demands [1, 2]. All new sources need small, low-loss optical parts that can focus, condense, monochromatize, filter, and/or focus radiation, as well as...

18. Analysis of corundum crystals optical and ultraviolet transmittance after electron beam exposureYury Cherepennikov12/09/2024, 17:30
Development of new materials and instrumentations for detection of charge particle beams and measuring their parameters are very topical in modern accelerator physics [1]. Cherenkov effect is well-known phenomenon that can be used for beam diagnosis. Commonly, diamond crystals is considered to be used as Cherenkov radiators for this purposes since this material has high resistance to radiation...

Computed tomography (CT) is a widely used method that provides huge opportunities for imaging the internal structure of different samples without disturbing their structures. During a CT scan, X-rays pass through a sample and detectors measure the radiation intensity after their interaction with this sample. The images directly obtained during the X-ray CT scan are two-dimensional projections...

Vertically aligned carbon nanotubes (VACNTs) are best candidate as emitters because of their high ordered structure, directional sensitivity and superior field emission performances. To understand the effective relation between field enhancement factor and surface morphology, we provide a protocol to quantitively characterize the topographic properties of nanotubes. After an efficient...

Previously, in experiments with irradiation of multi-walled carbon nanotubes, it was shown that nanotubes with a smaller number of layers are destroyed more strongly than thicker-walled nanotubes at the same irradiation fluences with He+ ions [1]. In this work, the ion-induced destruction of MWCNTs was modeled using the classical molecular dynamics method using the LAMMPS code [2] and AIREBO-M...

Recent advancements in radiobiology focus on the effects of ionizing radiation on biological systems, with a critical emphasis on understanding how radiation impacts DNA, as structural breaks in DNA are a primary cause of cellular death. Enhancing the efficacy of cancer treatments by combining radiation therapy with other modalities, such as chemotherapy and phototherapy, can mitigate the side...
