令和4年度は，従来からの感染症流行に加えて，物品価格の上昇および物品自体の調達の困難の影響が大きく，計画通りの進行ができなかった．実績の概要は，以下の4つの副課題毎にまとめる．1) 副課題1：可変径大口径イオン源の製作では，部品価格の高騰で，特にビーム径の制御機構の部分で当初設計の見直しが必要となった．そのため，部品は調達できたが，装置完成に至らず，現在なお組立途上にある．2) 副課題2：径方向散乱に注目した変調効果時間変化の模擬実験解析においては，昨年度手掛かりとして得たガス圧と高周波電力の調整によるビーム電流の飛躍的な増大を元に最適条件を探ったところ，収束電極への電圧印加で粒子束が急増することを見出した．これは実験的には好ましいものの，収束電極位置での空間電位が上昇するはずで，単純な粒子軌道計算結果とは整合しない．現象の理解には，副課題4の数値解析と密に関係させて進展させる必要がある．3) 副課題3：疑似自励発振の実現と生起条件の解析では，実験に必要な機材を製作依頼した企業が（年度当初から予想されたことではあるが）部品調達に困難を来たした．その結果，装置の納入が年度末近くとなり，ほとんど進展を得ることができなかった．4) 副課題4：模擬実験結果の数値解析においては，旧装置での過去の実験に合わせた解析で成果が得られた．減速電圧に対する依存性で，実験と同じ傾向が数値計算で再現されていた．これら合致する実験と計算は，見掛け上理論と整合していなかった．今回，計算で単一の粒子の軌道を微細に吟味することで，理論的な理解が得られた．この成果は，国際会議で発表し，現在，投稿した論文の審査が進んでいる．

In 2004, the prevalence of infectious diseases has increased, and there is an increase in the prevalence of infectious diseases. in the year of 2004, the prevalence of infectious diseases has increased in the year of 2004, and the number of items in the market is very high. The summary of the survey, the following 4 sub-topics: 1) Sub-topic 1: can be used as a tool for large-caliber equipment sources, and parts for high-end equipment. In the first place, the special equipment control organization designed to directly monitor the necessary equipment. The parts were up to standard, and the equipment was completed. Now, the equipment is on the way. 2) Sub-project 2: scattered attention in the direction of the path and attention to the results of the simulation. In the year of the year, the high-frequency power equipment of the high-frequency power plant was used to rectify the high-frequency power supply of the high-frequency power supply. The most important condition of the current supply system is to explore the most important condition. The beam cathode is printed on the particle beam, and the device is sent out in an emergency. The results of the particle path calculation show that the results are in good agreement with each other. The analysis of sub-topic 4 shows that it is necessary to analyze the conditions for the occurrence of suspected self-excited vibration. 3) Sub-topic 3: analysis of conditions for the occurrence of suspected self-excited vibration The necessary machinery and materials are based on the parts of the enterprise (which was expected at the beginning of the year). The results show that the equipment has been introduced into the end of the year, and the equipment has been successfully completed at the end of the year. 4) Sub-topic 4: model simulation results analysis of the number of results In the past, the results of the analysis of the old equipment have been successful. The high-speed electrical power plant is dependent on each other, and the temperature is calculated in the same way. The temperature is calculated again. The temperature is calculated by the combination of the two. This time, the calculation is based on the calculation of the particle cycle, the micrometer, the flavor and the temperature. I have a good understanding of the theory. as a result of the results, the National Council of the people's Republic of China has made a statement. Now, contributions have been made.
