These measurements are used for plasma control and machine protection. Latency is an important parameter in the assessment of such systems. It is a time gap between capturing an external event by hardware and finishing the processing of acquired data. PCS requires the diagnostic systems to introduce a maximum total latency of 10 to 100 ms, therefore, the systems need to be tested if they meet the requirements. The system evaluated in this paper is a reference real-time image acquisition system developed as a base for ITER diagnostic systems. It consists of hardware based on the Micro Telecommunications Computing Architecture (MicroTCA) standard, developed firmware, and software. It supports cameras with various interfaces. In the paper, two cameras, with a Camera Link and 1 GigE Vision interfaces were selected to perform latency evaluation. The paper presents two methods of measuring the latency of image acquisition. The first one is based on precise time stamping consecutive stages of acquisition. This approach allows for determining which step of acquisition takes more or less time. In consequence, the software or hardware can be optimized. The other one uses LED to evaluate a particular camera, by checking the time of camera reaction to the trigger. A dedicated testing framework is developed to perform automated tests to evaluate latency. It supports collecting and analyzing the results of measurements. Besides that, a dedicated hardware is used to perform the latency tests using LED. The results and discussion of the measurements are presented in the manuscript. They show the latency evaluated using earlier proposed methods, comparing the cameras used in the image acquisition system.</p></div>","PeriodicalId":634,"journal":{"name":"Journal of Fusion Energy","volume":"43 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10894-024-00411-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140927529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The divertor receives intense heat fluxes, potentially leading to damage to the plasma facing units. Hence, it is of major interest for the safety of divertor operation to detect and characterize the hot spots appearing on the divertor surface. This is done through the use of infrared (IR) cameras, which provide a thermal mapping of the divertor surface. In this work, a knowledge-informed divertor hot spot detector is demonstrated, that explicitly accounts for hot spot structure and temperature repartition. A novel neural network, termed as Constrained U-Net, is proposed, which uses as input the bounding boxes of hot spots from prior automatic detection. The Constrained U-Net addresses jointly image segmentation and regression of physical parameters, while remaining compatible with the practical constraints of real-time use. The detector is trained on simulated data and applied to real-world infrared images. On simulated images, it yields a precision of 0.98, outperforming a classical U-Net, and Max-Tree. Visual results obtained on real-world acquisitions from the WEST Tokamak illustrate the reliability of the proposed method for safety studies on hot spots.</p></div>","PeriodicalId":634,"journal":{"name":"Journal of Fusion Energy","volume":"43 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140927530","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}

The objective of this article is to show the benefit of artificial intelligence for improving a simple TPR system model written in Python to an accuracy approaching MCNP simulations, while significantly decreasing the computational cost. The first step was to model a polyethylene converter to obtain the energy-angle distribution of outgoing protons for a given incident neutron beam. When compared with MCNP, this simplified model was found to fail to account for proton energy and angular scattering. Therefore, in a second step, two neural networks were successfully trained to include these effects based on the output data of the TRIM code, assuming Gaussian distributions. The Python model was able to produce results very close (differences up to a few percent) to those obtained with MCNP by integrating these neural networks.

Subsequently, thermodynamic calculations have been used to establish the stability of such oxides in both ambient circumstances and liquid lead–lithium eutectic alloy (Pb–Li). The results showed that tungsten can provide a higher resistance to liquid metal attack than molybdenum because its oxides are more stable.

This method involves using a basic model in conjunction with a 3D transformed coordinate system. However, the absence of a clear solution method for the transformed coordinate system in MCNP presents a challenge. To address this issue, a solution method based on the axis attributes of the surfaces in MCNP and the composite nature of the 3D transformed coordinate system is developed. The improved one-to-many method has been applied to the neutron modeling of CFETR, and its reliability has been verified. In the neutron calculation model corresponding to the one-to-many and one-to-one methods, relative differences of the total TBR and nuclear heating are 0.25%, 0.07% respectively. The contribution of blanket modules to tritium breeding ratio (TBR) and nuclear heating has a relative difference within the range of − 0.25–0.55%. The relative differences of neutron flux and nuclear heating distribution for individual blanket modules #3–1 and #6–1 are within the range of − 0.60–0.40%.
