The MPEX device will be capable of ion fluxes of 1025 m−2s−1, power fluxes up to 40 MW/m2, ion fluences up to 1031 m−2, and operation at steady state for up to 106 s with magnetic fields up to 2.5 T. PMIs occur when the plasma directly impinges upon a surface. In the case of MPEX, this occurs primarily at the MPEX target. Observation of interaction using a variety of instruments is required. A PMI chamber was designed to enable these observations using currently envisioned diagnostics and to accommodate future instruments. The design includes 59 plasma-facing ports, 10 of which explicitly point at the target, and an additional 10 ports that can be used to assess the vacuum space in the chamber. The entire vacuum chamber is water-cooled and will experience sustained heat from plasma radiated power, microwaves, and neutral gas thermal loads. Because of the method of fabrication, this chamber has undergone significant manufacturability testing. The chamber includes provisions for chamber, plasma, and target diagnostics such as a residual gas analyzer, Thomson scattering lasers, and both visible and IR cameras. The design effort included operational testing of the autocoupler to ensure vacuum integrity and included machining and welding studies to verify that the tolerances required by the diagnostics could be held. Provisions have also been included to eventually accommodate a water-cooled target dump, an irradiated sample recovery module, and any other hardware needed to support future target designs and diagnostics.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"52 9","pages":"4103-4107"},"PeriodicalIF":1.3,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797988","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}

Inside a high vacuum environment, two stainless steel electrodes, spaced by a few centimeters gap, can achieve a voltage difference of up to 800 kV. During the electrode conditioning process, small current bursts, known as micro-discharges (MDs) occur, accompanied by the emission of X-rays, and of an overall increase in gas emission measurement. This study focuses on the fine dynamics of the MD phenomenon measured by the current signal and by the X-ray detectors, in an attempt to provide a possible physical interpretation of this mechanism. In particular, it appears that the MD fine dynamics are related to the growing asymmetry between the MD current values collected by the anode and cathode, observed during the electrode conditioning. The role of the vacuum chamber, acting as a third electrode, is investigated by an updated toy model, which evaluates the different current contributions collected from the two polarized electrodes, particularly those generated by secondary electron (SE) emission. The ratio of anode to cathode currents computed by the toy model closely matches the experimental one. Further experimental observations supporting the hypothesis of anode gas emission and expansion are discussed. Finally, a first study about the statistical distribution of the time intervals between successive MD suggests the occurrence of almost two different trigger mechanisms, evolving during the electrode conditioning process.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"52 9","pages":"4514-4519"},"PeriodicalIF":1.3,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798019","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}

One of the most complex and innovative subsystems of the entire project is certainly the negative-ion-based neutral beam injector (NBI), meant to inject 10 MW of auxiliary power with a beam of 510 keV deuterium neutrals. This contribution describes the conceptual design of the beamline for the DTT NBI system, with a particular focus on the innovative technical solutions adopted to fulfill the requirements and maximize the performance. The DTT NBI is required to operate with high efficiency in several operating scenarios, covering a large range of beam energies, between 10% and 100% of the nominal value (510 keV). To reach this challenging goal, an innovative accelerator design, the spherical and lemon hyperlens grids (SLHGs), has been developed. The implementation of this design concept of the accelerator has recently become possible thanks to recent improvements in additive manufacturing (AM) technology. Another original aspect of the DTT NBI, compared to existing devices, regards the vacuum pumping system, which will be based on nonevaporable getter (NEG) pumps. This will represent the first application of the NEG technology to an NBI for the heating and current drive system of a fusion experiment, with a possible simplification of the overall construction, with respect to typical solutions based on cryogenic pumps. Other innovative solutions are the cylindrical sawtooth structure (CSS) for the neutralizer panels and the stray field shielding system (SFSS) with encapsulated neutralizer. This article provides an overview of the injector for DTT NBI with a particular focus on innovative technical solutions.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"52 9","pages":"3802-3808"},"PeriodicalIF":1.3,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797970","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 this article, multicomponent magnetohydrodynamic (MHD) models of vacuum arc with passive and active anode modes will be reviewed, and the commercial alloy electrode materials in vacuum interrupters will be considered. The influence of the spatial magnetic field generated by commercial electrodes on the arc was studied. Furthermore, transient plasma characteristics and component evolution processes of vacuum arcs with different situations (fixed gap distance and electrode movement) in vacuum interrupters are reviewed. Vacuum arc plasma jet characteristics with a ring anode under different external magnetic fields will also be introduced, and the separation mechanisms of light and heavy ions in vacuum arcs will also be studied.

The PID controller generates control signals for the fast-feedback coils, resulting in successful control of the horizontal plasma position. However, the initial control system had some limitations. Therefore, it was upgraded using the Compact-RIO (c-RIO), for better control and flexibility in adjusting PID parameters.

The right eyes were exposed to 34.5-THz spot from fiber, and the contralateral eyes were used as control eyes.

Hematoxylin-eosin (HE) staining suggested the irradiated corneas over 2 min exposure contained fewer epithelial cell layers with vacuolated cells, swollen endothelium, and edematous stroma, compared to contralateral corneas.

Three separate emission regions in the I–V curves during sweep testing have also been observed.
