Programs based on the binary collision approximation, such as SDTrimSP, are often used to obtain these data. This paper describes an auxiliary code developed to compute parameters of sputtered and scattered particles using SDTrimSP. The code can be used to run SDTrimSP and to process its output, including parameterization of sputtering yields and angular distributions of emitted particles as functions of incidence angle and initial energy. A comparison is given of methods for generating particle parameters with prescribed characteristic distributions: approximations by Legendre polynomials and a “butterfly”-type distribution. The applicability of representing the ion distribution over solid angle as the product of azimuthal and polar parts is also investigated. It is shown that Legendre polynomials better describe the obtained dependence of the sputtered particle yield on polar angle than the butterfly distributions. The results will be used in the development of a plasma–surface interaction module for a Monte Carlo code under development, intended to simulate impurity and working-gas transport in fusion devices.","PeriodicalId":728,"journal":{"name":"Physics of Atomic Nuclei","volume":"89 1","pages":"S128 - S135"},"PeriodicalIF":0.5,"publicationDate":"2026-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2022, a lithium droplet injector (AO NIKIE) was developed to conduct real-time lithization during the discharge of T-11M tokamak, achieving excellent results. One of the drawbacks of this injector was the limited amount of lithium in the feed tank, which required its removal from the vacuum chamber of the tokamak and its depressurization for refueling. In 2024, a lithium injector with an external lithium refueling system without depressurizing the tokamak was developed. This paper presents the results of testing such an injector in the plasma discharges of the T-11M tokamak. Its performance was demonstrated experimentally; ten refuelings were performed without depressurizing the vacuum chamber of the tokamak. The main operating parameters of the injector were determined: the lithium microdroplet velocity ranged from 1.5 to 7 m/s, and the injected lithium flow varied from 10 to 70 mg/s. The effect of lithium droplet injection on the discharge parameters was studied. Calculations (modeling) of the distribution of ionized and neutral components of lithium in the plasma column were carried out.","PeriodicalId":728,"journal":{"name":"Physics of Atomic Nuclei","volume":"89 1","pages":"S147 - S155"},"PeriodicalIF":0.5,"publicationDate":"2026-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Replacing beryllium with tungsten increases a resistance of the wall to thermal loads and erosion but creates a risk of plasma contamination by a heavy impurity (tungsten) and complicates the pumping-out of light impurities. To solve these problems in ITER, the periodic wall boronization is proposed. A special attention is paid to the analysis of capabilities of H-alpha and Visible Spectroscopy (HA&VS) diagnostic to perform monitoring the impurities, primarily boron and tungsten, in the edge plasma layer (SOL) under the new ITER operational baseline. A list of spectral lines for recording the radiation from boron atoms and ions, as well as tungsten, is proposed. Furthermore, potential issues, such as the divertor stray light and the overlapping of spectral lines from different elements, are discussed. Using the numerical modeling (BM1D2V, SDTrimSP, SOLPS, and WallDYN3D codes), flux densities of the boron and tungsten atoms from the first wall due to sputtering by the deuterium atoms and ions were estimated for two characteristic divertor operating regimes. It is shown that the protective boron layer effectively shields the tungsten wall from an erosion but leads to the significant boron influx into the plasma. For radiation intensity calculation on HA&VS diagnostic cameras the Raysect and Cherab libraries were used. The calculations of radiation intensity on the selected spectral lines of boron demonstrate the feasibility of their recording by the HA&VS system and emphasize the importance of taking into account the wall reflectivity for the accurate signal interpretation.","PeriodicalId":728,"journal":{"name":"Physics of Atomic Nuclei","volume":"89 1","pages":"S177 - S194"},"PeriodicalIF":0.5,"publicationDate":"2026-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
