Upper and lower graphite divertors in Experimental Advanced Superconducting Tokamak (EAST tokamak) were replaced by tungsten divertors in 2014 and 2021, respectively. And boronization was performed in EAST to improve plasma performance in long pulse discharges and accumulate experiences for ITER operation with tungsten wall. Therefore, studies on the behavior of tungsten and boron and other...

An autoencoder (AE) is an unsupervised artificial neural network used to learn data patterns. By compressing data, an input signal is encoded into latent space variables and then decoded to reconstruct the input from these variables. This compression process, a form of dimensionality reduction, retains only the intrinsic characteristics of the signal, excluding non-descriptive elements. This...

The well-known physical properties of Chemical Vapor Deposition (CVD) diamonds have made them highly attractive for use as detectors in harsh environments characterized by high irradiation levels, such as those found in fusion machines [1]. Notably, their good radiation hardness, visible wavelength blindness, high carriersโ mobility, and high signal-to-noise ratio make diamond a promising...

Interferometric and polarimetric diagnostics are traditionally exploited in plasma experiments, and, in particular, in magnetically confined fusion experiments, to determine plasma electron density and to give valuable information on the internal magnetic fields, respectively [1]. These information enter into the evaluation of the plasma magnetic equilibrium and in particular into the...

Thin diamond detectors have proven to be excellent diagnostic tools for plasma diagnostic in a tokamak machine for the detection of soft X (SX) and UV radiation [1]. Furthermore, thanks to the excellent physical properties of diamond, i.e. wide band-gap, fast response time and radiation hardness, diamond detectors are among the alternative diagnostic tools in the next generation fusion...

Achieving controlled fusion necessitates the confinement of hot plasmas within devices
called tokamaks, which use magnetic fields for this purpose. Accurate measurement of
total radiation and impurities in these plasmas is crucial for optimizing performance and
ensuring safety.

Laser-induced graphene (LIG) is prepared by single step laser writing processes on many carbonaceous material [1]. By Raman spectroscopy it is observed that the laser scribing on a polymeric material with hexagonal structure, such as polyimmide (Kapton), induces a breaking of C-O, C=O and C-N bonds, with consequent rearrengement of carbon atoms to form a graphene structure. Depending on the...

New X-ray spectra of tungsten have been observed using the X-ray Crystal Spectrometer (XCS) on the Experimental Advanced Superconducting Tokamak (EAST). The wavelength of these new x-ray spectra ranges from 3.895 ร to 3.986 ร . It is tentatively determined that the unidentified spectra measured by X-ray crystal spectrometer in EAST are emitted from W43+, W44+ and W45+ [1]. However, there is no...

One of the milestones to be achieved in the design of the bolometric diagnostics for the new Italian Divertor Tokamak Test (DTT) project [1] is the estimation of the radiated power for the start of the operation, i.e the so called Phase 1. Such an achievement has several implications, ranging from the scientific analysis and planning of the discharges between shots to the feedback protection...

High electron temperature(Te) is an important parameter for future fusion reactors. Among the most common techniques used to evaluate Te are incoherent Thomson scattering (TS) and electron cyclotron emission (ECE). Due to the different diagnostic application conditions brought by different measurement principles and certain limitations of technology, it is difficult to maintain absolute...

Imaging optics for plasma diagnostics in fusion experiments are challenging systems, since they have to face extreme heat and radiation fluxes. These problems can be partially addressed by means of reflective systems, which are easier to cool and less sensitive to radiation damage. On the other hand, reflective systems tend to be bulkier because on their intrinsic folding, and less suited for...

It is well-known that in tokamaks, measuring electron temperatures in the plasma core can become problematic when certain values are reached, typically exceeding 6-8 keV [1]. Discrepancies often arise between the values provided by different diagnostics, such as Thomson Scattering and Electron Cyclotron Emission (ECE), which are expected to agree. Accurate and reliable determination of...
