While current 3D imaging capabilities use multiple lines of sight to perform image reconstruction, it would be highly desirable to use only one line of sight, as this would significantly reduce the number of windows in the target hohlraum and decrease their impacts on implosion symmetry. Such a goal is achievable using the zone plate coded imaging technique developed by N. M. Ceglio [Proc. SPIE 0106, 55-62 (1977)]. It consists of fielding a visible light Fresnel zone plate on shot to record a shadowgraph. The image can then be reconstructed either by printing the shadowgraph on a transparent film and shining a suitable wavelength light through it or by numerical reconstruction. A new approach using numerical reconstruction is presented, and it relaxes the constraint by an order of magnitude on the optic design, thus enabling an easier fabrication process, as it allows a scaling-up of the optic dimensions. The design, fabrication process, and testing with an x-ray source of a prototype is presented. The reconstruction of an ∼14.5 × 17 μm2 broadband x-ray source was successful and shows that the performances are in line with expectation with an at least 5 mm axial resolution.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some inchworm piezoelectric actuators, composed of multiple piezoelectric stacks, can realize two-degree-of-freedom motion but still fail to simplify the complex structures and struggle to achieve high output speed without backward motion. Here, we design an inchworm piezoelectric actuator that can carry out planar motion with a compact centrosymmetric structure in which only three piezoelectric stacks are used. The amplification mechanisms based on flexure hinges are designed to increase the clamping force and step displacement. A working principle of single-dual mode is designed to effectively utilize the deformations of the driving units, and two steps in one cycle are realized, which improves the output speed of the proposed actuator. Utilizing its center symmetry structure to switch the direction of motion, which enables plane motion. The parameters of the driving units were optimized by theoretical analyses. Then, the finite element method and experiments were employed for the static and dynamic analyses. Experimental results demonstrated the actuator's capability of point-to-point positioning and tracking a circle within the plane and revealed the maximum speeds of 2085 μm/s along the X-axis and 2407.5 μm/s along the Y-axis without backward motion. Herein, a combination of a simple structure and a good output speed without backward motion is achieved on a planar motion inchworm actuator.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144014799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite substantial advancements in crack detection through deep neural networks, their reliance on pixel-level crack annotation escalates labeling costs and renders the labeling procedure time-intensive. Consequently, academics have suggested multiple Explainable Artificial Intelligence (XAI) methodologies to enhance the efficacy of pseudo-labeling. However, fractures' slender, continuous, and inconspicuous characteristics render current XAI approaches ineffective in adequately gathering feature information. This work examines the characteristics of many XAI strategies through extensive experimentation. It synthesizes the advantages of each strategy to mitigate the uncertainty error associated with a singular model in the fracture region. Moreover, we formulate and implement various integration strategies to mitigate and enhance the discrepancies across distinct XAI algorithms across two separate datasets. The experimental results indicate that the proposed method provides more accurate basic annotations for weakly supervised crack segmentation.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144023593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-level rf (LLRF) systems are employed to set the phase and amplitude of the field in the accelerating structure and to compensate for the pulse-to-pulse fluctuation of the rf field in the accelerating structures with a feedback loop. The LLRF systems are typically implemented with analog rf mixers, heterodyne-based architectures, and discrete data converters. There are multiple rf signals from each of the rf stations, so the number of rf channels required increases rapidly with multiple rf stations. With a large number of rf channels, the footprint, component cost, and system complexity of the LLRF hardware will increase significantly. To meet the design goals of being compact and affordable for future accelerators, we have designed the next-generation LLRF (NG-LLRF) with a higher integration level based on RFSoC technology. The NG-LLRF system samples rf signals directly and performs rf mixing digitally. The NG-LLRF has been characterized in loopback mode to evaluate the performance of the system and has also been tested with a standing-wave accelerating structure, a prototype for the Cool Copper Collider (C3) with a peak rf power level up to 16.45 MW. The loopback test demonstrated amplitude fluctuation below 0.15% and phase fluctuation below 0.15°, which are considerably better than the requirements of C3. The rf signals from the different stages of the accelerating structure at different power levels are measured by the NG-LLRF, which will be critical references for the control algorithm designs. The NG-LLRF also offers flexibility in waveform modulation, so we have used rf pulses with various modulation schemes, which could be useful for controlling some of the rf stations in accelerators. In this paper, the high-power test results at different stages of the test setup will be summarized, analyzed, and discussed.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"96 4","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144026258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
