For more than a century, X-ray imaging has been largely synonymous with absorption contrast. Today, however, advances in detector technology are fundamentally changing this paradigm. Modern detectors are evolving from passive image sensors into instruments that determine which physical property of the X-ray beam is measured. Beyond attenuation, they can now provide access to photon energy,...

Plasma-wakefield accelerators sustain GV/m-scale gradients, but shot-to-shot reproducibility remains the main obstacle to user-oriented operation. Diagnosing and controlling this instability requires measuring the plasma itself, not just the beam.

Electron temperature (Te) measurements in magnetized fusion plasmas rely heavily on Electron Cyclotron Emission (ECE) radiometry and High-Resolution Thomson Scattering (HRTS). While both diagnostics are routinely used to reconstruct Te profiles, significant discrepancies often emerge in specific operational regimes, particularly in high-performance plasmas approaching reactor-relevant...

Discrepancies between the Electron Cyclotron Emission (ECE) and Thomson Scattering measurements of electron temperature were observed on JET, TFTR and more recently on FTU and JET in high performance , high electron temperature ( Te>7KeV) plasmas in Deuterium-Tritium Campaigns. The physics basis of the differences of ECE and Thomson scattering measurements can be identified in the way the...

A Lithium Beam Emission Spectroscopy (Li-BES) has been successfully developed on EAST [S. Zoletnik et al 2018 Rev. Sci. Instrum. 89 063503], providing measurement of density fluctuation in the pedestal and SOL regions with high spatial and temporal resolutions. This diagnostic enabled us to conduct a series of important physics studies. A non-axisymmetry distribution of edge coherent mode...

Two sets of Low Energy Neutral Particle Analyzers (LENPAs) and Quartz Crystal Microbalances (QMBs) have been deployed on EAST to investigate the erosion and deposition processes of first wall materials (FWMs) within magnetic shadow areas (MSAs). These processes affect the lifetime of the first wall components and the fuel retention in the device, thereby posing a potential threat to the safe...

To meet the demand for a high-stability collinear orthogonally polarized light source in far-infrared polarimetric interferometers and Cotton-Mouton polarimeters for tokamak plasma diagnostics, a novel optically pumped twin far-infrared laser based on formic acid (HCOOH) gas is developed in this paper. The laser adopts an innovative integrated design of dual resonant cavities, where the two...

Accurate measurement of high electron temperature is of great importance for the study of high-performance plasmas on EAST and for future fusion devices. Thomson scattering (TS) and electron cyclotron emission (ECE) are two of the most widely used diagnostics for electron temperature measurement. Discrepancies between TS and ECE in the high-temperature regime have been reported and...

Magnetic diagnostics are essential for the measurement and control of plasma behavior in magnetic confinement fusion devices. However, conventional wound-coil magnetic probes face increasing challenges in future fusion reactors, including material degradation under strong nuclear radiation and high-energy neutron irradiation, as well as limited installation space caused by their relatively...

Infrared thermography is routinely used for surface temperature measurement of plasma-facing components in tokamaks, but metallic divertor targets introduce uncertainties related to surface emissivity and optical transmission [1]. To improve the temperature measurement capability of the EAST lower divertor, a near-infrared/short-wavelength infrared two-color thermography system has been...

Visible optical diagnostics in tokamaks can be significantly affected by stray light, which is mainly generated by multiple reflections of plasma radiation from plasma-facing components. Because plasma-wall interactions continuously modify wall morphology and optical properties, models based on unexposed materials may fail during long-term operation. This study investigates the evolution of...
