Abstract

The ITER Heating Neutral Beam (HNB) injectors, one of the tools necessary both to achieve burning conditions and to control plasma instabilities, are characterized by such demanding parameters as to require the construction of a Neutral Beam Test Facility (NBTF) dedicated to their development and optimization. The NBTF was realized in Padua (Italy), with the direct contribution of the Italian government, through the Consorzio RFX as the host entity, IO, the in kind contributions of three Domestic Agencies (F4E, JADA, INDA) and the technical and scientific support of various European laboratories and universities. The NBTF hosts two experiments: SPIDER and MITICA. The former is devoted to the optimization of the HNB and DNB ion sources and to the achievement of the required source performances. MITICA is the full size prototype of the ITER HNB, with an ion source identical to the one used in SPIDER. This paper gives an overview of the progress of the NBTF realization with particular emphasis on issues discovered during this phase of activities and to the adopted solutions in order to minimize the impact on the schedule while maintaining the goals of the facilities. The realization of MITICA is well advanced; it is expected to enter into operation in 2023 due to the long procurement times of the in-vessel mechanical components. The power supply designed to operate at 1MV are in an advanced phase of realization; all the high voltage components have been installed and the complex insulation test phase has begun in 2018. The construction and installation of SPIDER plant systems was successfully completed with their integration into the facility. The mechanical components of the ion source were installed inside the vessel and connected to the plants. The integrated commissioning with control (CODAS), protection and safety systems ended positively and the first experimental phase began. Finally, the first results of the SPIDER experimentation and of the 1MV insulation tests on the MITICA high voltage components are presented.

Abstract

Several novel design solutions for high performance cooling systems have been developed by Consorzio RFX, permitting to simulate the challenging heat transfer conditions foreseen in the future fusion devices. The project, called Multi-design Innovative Cooling Research & Optimization (MICRO), aims, on one hand, to verify the present solution applied inside the MITICA experiment and, on the other, to perform further improvements in the heat transfer process with an acceptable pressure drop and reliable manufacturing process. A comprehensive parametric investigation has been carried out with the goal of comparing various design options and establishing a standard approach to be applied in several devices, characterized by comparable heat loads both in terms of spatial distribution and amplitude. The main advantages rely on the possibility to extend the fatigue life-cycle of different high thermal stress components and to investigate the possibility to employ alternative dielectric fluids instead of water. Such design solutions would in fact allow the exploitation of less performing fluids in terms of cooling capability. Despite the unavoidable deterioration of the cooling performances such approach would represent a significantly advantageous option with respect to the existing ultrapure water technologies. This is particularly relevant in view of DEMO and future power plants characterized by higher efficiency and reliability. The paper gives a detailed description of the Computation Fluid Dynamics (CFD) analysis and the samples manufacturing process.

Abstract

The ITER Neutral Beam Test Facility (PRIMA) is plan ned to be built at Consorzio RFX (Padova, Italy). PRIMA includes two experimental devices: an ITER-si ze ion source with low voltage extraction called SPIDER and the prototype of the ITER Heating Neutra l Beam Injector (HNB) called MITICA. The purpose of MITICA is to demonstrate that all th e operational parameters of the ITER HNB accelerato r can be experimentally achieved with reasonable marg in, thus establishing a large step forward in the performances of neutral beam injectors in compariso n with the present experimental devices. The design of the MITICA accelerator, here describe d in detail, has been developed in order to satisfy with reasonable margin all the operational requirements of the ITER HNB. An integrated approach, taking int o consideration at the same time physics and engineer ing aspects, has been adopted throughout the design process. Particular care has been applied also to s upporting and validating the design on the basis of the expertise and experimental data made available by t he neutral beam laboratories of CEA, IPP, CCFE, NIF S and JAEA. The aim of this report is to finalize the design of the MITICA accelerator, by comparing the design co ncepts that were found to be the best performing from prev ious analyses and choose the most suitable one to b e adopted in the MITICA experiment. An optimization p rocess is set up by developing subsequent design solutions through discussion and comparisons of the results of simulations, taking into account the advantages and drawbacks of the different design ch oices. This report presents a the studies on differ ent possible geometries and magnetic configurations for the MITICA accelerator carried out during 2014.

43. Targeted mutations in a Trametes villosa laccase. Axial perturbations of the T1 copper.

Author

Xu, F, Palmer, A E, Yaver, D S, Berka, R M, Gambetta, G A, Brown, S H, and Solomon, E I

Abstract

Trametes villosa laccase was mutated on a tetrapeptide segment near the type 1 site. The mutations F463M and F463L were at the position corresponding to the type 1 copper axial methionine (M517) ligand in Zucchini ascorbate oxidase. The mutations E460S and A461E were near the T1 copper site. The mutated Trametes laccases were expressed in an Aspergillus oryzae host and characterized. The E460S mutation failed to produce a transformant with meaningful expression. The F463L and A461E mutations did not significantly alter the molecular and enzymological properties of the laccase. In contrast, the F463M mutation resulted in a type 1 copper site with an EPR signal intermediate between that of the wild type laccase and plastocyanin, an altered UV-visible spectrum, and a decreased redox potential (by 0.1 V). In oxidizing phenolic substrate, the mutation led to a more basic optimal pH as well as an increase in kcat and Km. These effects are attributed to a significant perturbation of the T1 copper center caused by the coordination of the axial methionine (M463) ligand.

Abstract

The diverticular disease is rarely located in the small intestine (0.1-1.4%). The most important feature is due to the lack of a typical symptomatology which may appear only on the occasion of the complications it may incur (perforation, haemorrhage and so on). It isn't also infrequent that the surgeon may observe intestinal diverticula accidentally, on the occasion of laparotomies carried out in emergency or for other pathologies. The literature on intestinal diverticula is reviewed and personal experience in a clinical case presenting as acute abdomen is described.

Abstract

Aims: This multicenter and prospective study was aimed at examining the appropriate use of upper gastrointestinal endoscopy in an open access system (primary endoscopy) using the American Society for Gastrointestinal Endoscopy (ASGE) guidelines. We also wished to see whether these guidelines can be easily used in clinical practice. Materials and methods: Three thousand four hundred fourteen upper gastrointestinal endoscopies performed in seven endoscopy units of different size were studied prospectively. The real indication, to be compared with the guidelines, was determined by the endoscopist before performing the examination, based on the patient's history. Results: Seven hundred eighty-one (23%) endoscopies were ''generally not indicated,'' according to ASGE guidelines, and were distributed as follows: follow-up of duodenal ulcer healing (33%), follow-up of other healed benign diseases (24%), surveillance of gastric atrophy, pernicious anemia, metaplasia, treated achalasia, and prior gastric intervention (14%), diagnosis of dyspepsia considered functional in origin (13%), and uncomplicated heartburn responding to medical therapy (7%). Endoscopies ''generally not indicated'' accounted for 23% in the bigger endoscopy units, 24% in the average sized units, and 22% in the smaller ones. They accounted for 32% when the examination was prescribed by family doctors, 17% when prescribed by internists, 19% by surgeons, and 14% by gastroenterologists ( p < 0.001). Eighty-six (2.5%) endoscopies were done for indications not provided in the guidelines. Conclusions: This study shows that ASGE guidelines are complete and easy to use and that the rate of inappropriate indications in an open access system can be considerable. They occurred mainly in the follow-up of healed benign disease and were more frequent when the examination was prescribed by the family doctor. (Gastrointest Endosc 1995;42:387-9.)

Abstract

Heating neutral beam (HNB) injectors, necessary to achieve burning conditions and to control plasma instabilities in ITER, are characterized by such demanding parameters that a neutral beam test facility (NBTF) dedicated to their development and optimization is being realized in Padua (Italy) with direct contributions from the Italian government (through Consorzio RFX as the host entity) and the ITER international organization (with kind contributions from the ITER domestic agencies of Europe, Japan and India) and technical and scientific support from various European laboratories and universities. The NBTF hosts two experiments: SPIDER, devoted to ion source optimization for the required source performance, and MITICA, the full-size prototype of the ITER HNB, with an ion source identical to SPIDER. This paper gives an overview of the progress towards NBTF realization, with particular emphasis on issues discovered during this phase of activity and on solutions adopted to minimize the impact on the schedule and maintain the goals of the facilities. The realization of MITICA is well advanced; operation is expected to start in 2023 due to the long procurement time of the in-vessel mechanical components. The beam source power supplies, operating at 1 MV, are in an advanced phase of realization; all high-voltage components have been installed and the complex insulation test phase began in 2018. At the same time, construction and installation of SPIDER plant systems was successfully completed with their integration into the facility. The mechanical components of the SPIDER ion source were installed inside the vessel and connected to the plants. Integrated commissioning with the control, protection and safety systems ended positively and the first experimental phase has begun. The first results of the SPIDER experiment, with data from operational diagnostics, and the plans for the 1 MV insulation tests on the MITICA high-voltage components are presented.

Abstract

A speech addressed by Leonardo Melandri to the first elected Regional Council of Emilia-Romagna, in 1971, is the starting point to discuss and assess the process which led to the devolution, from the central government to the regional administrations, of the functions for agricultural policy implementation in Italy. It was a very difficult and contradictory transition, starting a long period, in which the Italian policy making activity related to agriculture was heavily hindered by uncertainty about the institutions responsible for the administrative and financial management of the measures decided at both, the national and the European level. Major critical points have been found in the large partiality of the devolution process, in the initial exclusion of the regional administrations from the implementation of the European Common agricultural policy, and in the fragmentation of the actions for land reclamation, forestry policy, and rural development.

Abstract

A set of novel design solutions for high performance cooling systems have been developed and tested by Consorzio RFX, achieving, with experimental tests, the challenging heat transfer conditions foreseen for Heating and Current Drive Systems of present and future nuclear fusion devices. The project, called Multi-design Innovative Cooling Research & Optimization (MICRO), has the triple objective of: • Verifying the full qualification of the manufacturing process and assess the cooling performance of the present solutions applied on the acceleration grids designed for ITER Heating Neutral Beam Injectors and MITICA experiment, which have similar heat loads as for DEMO1. • Identifying alternative designs realizable with presently qualified manufacturing processes for improving heat transfer mechanisms with limited pressure drops. • Developing further optimized solutions by means of the investigation of the interrelated effects of geometric parameters and thermofluid dynamic properties of the coolant fluid. The main aim of present work is to extend the fatigue life-cycle of high thermal stress components. In the first part of the paper the design description and constraints are presented together with the results obtained from numerical analyses carried out on the full-scaled model of the electrostatic grids; the outcomes of the experimental campaign, together with the characterization of the properties and performance of a set of alternative dielectric fluids, are shown in the second one.

Abstract

SPIDER is one of two projects of the ITER Neutral Beam Test Facility under construction in Padova, Italy, at the Consorzio RFX premises. It will have a 100 keV beam source with a full-size prototype of the radiofrequency ion source for the ITER neutral beam injector (NBI) and also, similar to the ITER diagnostic neutral beam, it is designed to operate with a pulse length of up to 3600 s, featuring an ITER-like magnetic filter field configuration (for high extraction of negative ions) and caesium oven (for high production of negative ions) layout as well as a wide set of diagnostics. These features will allow a reproduction of the ion source operation in ITER, which cannot be done in any other existing test facility. SPIDER realization is well advanced and the first operation is expected at the beginning of 2018, with the mission of achieving the ITER heating and diagnostic NBI ion source requirements and of improving its performance in terms of reliability and availability. This paper mainly focuses on the preparation of the first SPIDER operations - integration and testing of SPIDER components, completion and implementation of diagnostics and control and formulation of operation and research plan, based on a staged strategy
