Analysis and understanding of wall erosion, material transport fuel retention are among the most important tasks for ITER future devices, since these questions determine largely lifetime availability fusion reactor. These data also extreme value to improve validate models in vessel build-up T inventory D–T devices. So far, research areas is supported by post-mortem analysis tiles. However, access samples will be very much restricted next-generation devices (such as ITER, JT-60SA, W7-X, etc)...
The provision of a particle and power exhaust solution which is compatible with first-wall components edge-plasma conditions key area present-day fusion research mandatory for successful operation ITER DEMO. work package plasma-facing (WP PFC) within the European programme complements laboratory experiments, i.e. in linear plasma devices, electron ion beam loading facilities, studies performed toroidally confined magnetic such as JET, ASDEX Upgrade, WEST etc. connection both groups done via...
Abstract Laser-induced breakdown spectroscopy (LIBS) is one of the most promising methods for quantitative in-situ determination fuel retention in plasma-facing components (PFCs) magnetically confined fusion devices like ITER and JET. In this article, current state understanding LIBS development applications will be presented, based on a complete review existing results complemented with newly obtained data. The work has been performed as part research programme, set up EUROfusion...

Licensing for building has been granted at end 2021. Cat. A radiologic source also 2022. The toroidal field magnet system progressing. prototype 170 GHz gyrotron produced it now under test on FALCON design vacuum vessel, poloidal coils civil infrastructures completed. shape first DTT divertor agreed with EUROfusion to different plasma exhaust...
Methods for rapid identification of explosives and their associated compounds at trace level quantities are needed security screening applications. In this paper, we apply the surface‐enhanced Raman spectroscopy (SERS) to detect identify traces (as low as tens pg) pentaerythritol tetranitrate (PETN), ethylene glycol dinitrate (EGDN), cyclotrimethylene‐trinitramine (RDX) trinitrotoluene (TNT) using commercially available substrates (Klarite®, Renishaw diagnostics). High quality spectra were...
Recently, solid state photovoltaic Schottky diodes, able to detect ionizing radiation, in particular, x-ray and ultraviolet have been developed at the University of Rome “Tor Vergata.” We report on a physical electrical properties analysis device detailed study its detection capabilities as determined by properties. The design is based metal/nominally intrinsic/p-type diamond layered structure obtained microwave plasma chemical vapor deposition homoepitaxial single crystal followed thermal...
Recently, a compact solid-state neutron detector capable of simultaneously detecting thermal and fast neutrons was proposed [M. Marinelli et al., Appl. Phys. Lett. 89, 143509 (2006)]. Its design is based on p-type/intrinsic/metal layered structure obtained by Microwave Plasma Chemical Vapor Deposition (CVD) homoepitaxial diamond followed evaporation an Al contact L6iF converting layer. Fast are directly detected in the CVD bulk, since they have enough energy to produce C12(n,α)B9e reaction...
Since the 2012 IAEA-FEC Conference, FTU operations have been largely devoted to runaway electrons generation and control, exploitation of 140 GHz electron cyclotron (EC) system liquid metal limiter elements. Experiments on shown that measured threshold electric field for their is larger than predicted by collisional theory can be justified considering synchrotron radiation losses. A new control algorithm was developed tested in presence a current plateau, allowing minimize interactions with...
Fast monitoring of water quality is a fundamental part environmental management and protection, in particular, the possibility qualitatively quantitatively determining its contamination at levels that are dangerous for human health, fauna flora. Among techniques currently available, Raman spectroscopy variant, Surface-Enhanced Spectroscopy (SERS), have several advantages, including no need sample preparation, quick easy operation ability to operate on field. This article describes...
In this paper the Laser Induced Breakdown Spectroscopy (LIBS) measurement of deuterium (used as a proxy for tritium) retained in and surface elemental composition FTU Mo (TZM) toroidal limiter tiles, carried out from remote (∼2.5 m) during short breaks operations or machine maintenance, are reported. Single pulse technique has been used with vessel under high vacuum Nitrogen Argon atmosphere. experiments Dα Hα lines have detected good resolution, while Ar atmosphere (5 × 104 Pa) two were...
Surface‐enhanced Raman spectroscopy (SERS) measurements on 1,3,5‐trinitroperhydro‐1,3,5‐triazine were performed with a table‐top micro‐Raman system exciting the analyte diode laser emitting at 785 nm.

An innovative route for deep-submicrometer spatial resolution hard x-ray microscopy with tabletop source is proposed. A film of lithium fluoride (LiF) was used as imaging detector in contact mode. We present here the images recorded on LiF films a Fresnel zone plate submicrometer gold structures and an onion cataphyll. The were read optical confocal microscope fluorescence measured about 250nm, i.e., close to limit microscope. advantages drawbacks, possible improvements, this are discussed.
Diamond exhibits many properties such as an outstanding radiation hardness and fast response time both important to design detectors working in extremely radioactive environments. Among the applications these devices can be used for, there is development of a hard neutron detector for next generation fusion reactors, International Thermonuclear Experimental Reactor project, under construction at Cadarache France. A technology routinely produce electronic grade synthetic single crystal...
